I was amazed at the number of turtle species there are in Florida!

 

In fact, there are so many species I have broken them down into a few different categories.

 


Today, you will learn about the 28 different kinds of turtles in Florida.

 


Freshwater Turtles in Florida:

Freshwater Turtles make up the largest group of turtles native to Florida. They are strong swimmers and spend most of their lives in or very near water.


#1. Common Snapping Turtle

  • Chelydra serpentina

types of turtles in florida

Identifying Characteristics:

  • Weighs 10 to 35 lbs. and is 8 to 18 1/2 inches long.
  • The snapping turtle has a long tail, chunky head, and large webbed feet.
  • The carapace (upper shell) coloring is black, brown, or olive with no distinct pattern.

 

Snapping Turtles are widespread throughout Florida.

 

Look for them living in marshes, lakes, ponds, rivers, and slow streams. They prefer areas with plenty of aquatic vegetation to hide in, and insects, fish, frogs, and birds to eat.

Snapping Turtles are best known for their powerful jaws. While there aren’t any recorded incidents of one of their bites causing amputation to a person, it can cause infections serious enough to require an amputation. In fact, their jaws are so strong that snapping turtles commonly eat other turtles!

 

These turtles are usually docile but will become very aggressive if removed from the water. One of the best ways to calm an aggressive individual is to place it back into the water, where it can feel safe. I know I have personally picked them up with a large snow shovel to get them off the road and back to safety!

 


#2. Alligator Snapping Turtle

  • Macrochelys temminckii

species of turtles in florida

Identifying Characteristics:

  • Weighs 35 to 115 lbs. and is 15 to 20 inches long.
  • Alligator Snapping Turtles have long, tough shells with triangular ridges resembling an alligator’s back.
  • The carapace coloring is black, brown, or olive. The green tips of the carapace are not natural coloring, but algae!

 

Alligator Snapping Turtles are larger than Common Snapping Turtles but don’t bite as often. They prefer living in the deeper water of canals, rivers, swamps, and lakes.

Alligator Snapping Turtle Rangemap:

 

This species is the largest freshwater turtle found in Florida!

 

These massive reptiles can grow up to 115 pounds in weight and grow to be two feet in length.

 

Alligator Snapping Turtles have an interesting way of finding food. Instead of hunting, they often lie on the bottom of a body of water and lure fish with a pink worm-like appendage in their mouth! Once their prey gets close enough, they ambush their meal.

 

The Alligator Snapping Turtle’s powerful jaws can bite with 1,000 lbs of force!

 

So let’s put this in perspective. If you were bitten by one of these large turtles, it would have the same force as having a small car dropped on it! As you can imagine, they are extremely dangerous and should never be handled in the wild. Even professionals and very experienced herpetologists have been severely injured by their bite!

 

Two species that are closely related to the Alligator Snapping Turtle can also be found in Florida. The Suwannee Alligator Snapping Turtle (Macrochelys suwanniensis) is the largest of its family, with a prominent hooked beak and three very high keels on the back. The Apalachicola Alligator Snapping Turtle (Macrochelys apalachicolae) is similar in looks to the Common Snapping Turtle.

 


#3. Barbour’s Map Turtle

  • Graptemys barbouri

 

Identifying Characteristics:

  • Females are 7 to 10.75 inches long. Males are much smaller, only 3.5 to 5.25 inches long.
  • The females’ heads are extremely large compared with other map turtles.
  • The carapace coloring is light brown to olive green, sometimes with lighter “C” shaped markings.

 

Barbour’s Map Turtles are limited to a few river systems in the Florida panhandle. 

They are common within their range but are still considered a vulnerable species because their range is so limited. Your best chance to see a Barbour’s Map Turtle is to catch one basking on a log close to the riverbank. 

 


#4. Escambia Map Turtle

  • Graptemys ernsti

 

Identifying Characteristics:

  • Females are up to 11.25 inches long. Males are much smaller, only 2.75 to 5 inches long.
  • There is a light blotch behind the eyes, separate from the other lines on the head.
  • The carapace is olive green with a dark brown to black stripe along the keel.

 

The Escambia Map Turtle is found in a small western part of the Florida panhandle, in large rivers with sandy bottoms. Its diet is carnivorous, and males prefer insects or their larvae, while females eat primarily mussels and clams.

Escambia Map Turtles have a limited range in the Florida Panhandle. They are closely related to the Barbour’s Map Turtle, and even cross-breed with the species where their ranges overlap!

 

They are ONLY found in river systems that drain into the Escambia Bay, which is how this species got its name!

 


#5. Diamond-Backed Terrapin

  • Malaclemys terrapin

common turtles in florida

Identifying Characteristics:

  • Females are 6 to 9.25 inches; males are 4 to 5.5 inches.
  • Concentric rings are formed in each carapace section, either as grooves and ridges or as alternating light and dark lines.
  • Skin is gray with black flecks and spots over the limbs and head.

Diamond-Backed Terrapins are the ONLY freshwater turtle in Florida adapted to live in salty water!

 

They are found along the coast in salt marshes, tidal flats, brackish streams, and barrier beaches. Incredibly, they can also live in full-strength saltwater for extended amounts of time.

Diamond-Backed Terrapin Rangemap:

 

Diamond-Backed Terrapins have evolved to be extremely well-adapted to life in saltier coastal waters, even though they look similar to their freshwater cousins. For example, here are a few unique ways they obtain fresh drinking water.

  • They will drink the top layer of freshwater that forms on brackish or saltwater when it rains.

  • They tip their heads up with open mouths to catch raindrops as they fall!

 

There are SEVEN different subspecies of Diamond-Backed Terrapins. They are separated by their location along the east coast, ranging from New England all the way to the Gulf of Mexico. There are FIVE subspecies that live in Florida, the most of any state! The Eastern Florida, Mangrove, and Ornate Diamond-Backed Terrapins are ONLY found in Florida. 

  • Carolina Diamond-Backed Terrapin (M. t. centrata)
    • The plastron (lower shell) curves inward at the base of the tail, meeting the carapace.
  • Eastern Florida Diamond-Backed Terrapin (M. t. tequesta)
    • The carapace does not have rings, and the middle of each scute is only slightly darker than the outside.
  • Mangrove Diamond-Backed Terrapin (M. t. rhizophorarum)
    • The neck and back legs have dark, bold stripes instead of the usual spots.
  • Ornate Diamond-Backed Terrapin (M. t. macrospilota)
    • The carapace has a dorsal keel, or center ridge, with large round bumps running its length.
  • Mississippi Diamond-Backed Terrapin (M. t. pileata)
    • The carapace is the darkest of the sub-species, usually almost uniformly black.

 

In the video below, you can see examples of many sub-species of Diamond-Backed Terrapins!

 


#6. River Cooter

  • Pseudemys concinna

types of turtles in florida

Identifying Characteristics:

  • 9 to 13 inches long.
  • The carapace is brown to olive or dark green, with lighter c-shaped and concentric markings in the scutes (sections).
  • Five lighter-colored stripes between the eyes.

 

River Cooters are highly omnivorous and will eat almost anything they can swallow!

 

This includes aquatic vegetation, land plant matter, and animals both alive and dead! They are enthusiastic hunters and will go to land to catch insects or worms, then return to the water to eat them.

Despite their large appetites and aggressive hunting style, these turtles share their habitat in northwestern Florida with many other turtle species. In fact, they are often seen basking in groups with Painted Turtles and sliders. River Cooters are even seen stacked on top of one another!

 

When it comes to breeding, the female River Cooter is very selective! Males have a sort of “dance” they do when trying to mate with a female, vibrating their long nails and waving their arms in the female’s face. Often, she will ignore potential mates who try to court her until one meets her approval! 

 


#7. Coastal Plain Cooter

  • Pseudemys floridana

species of turtles in florida

Identifying Characteristics:

  • 9 to 13 inches long. The record is 16 inches.
  • The carapace is brown to olive or dark green.
  • Light vertical stripes on the carapace differentiate the Coastal Plain Cooter from its cousins.

 

The Coastal Plain Cooter is one of the largest cooter turtle species in Florida!

 

Coastal Plain Cooters live in lakes, swamps, marshes, and rivers in northern Florida. Coastal Plain Cooters are primarily herbivorous, but they will eat insects if they are abundant and easily caught.

Coastal Plain Cooter Rangemap:

This turtle is in decline in Florida due to excessive hunting for the meat and pet trades.

 

It’s estimated that 60% of Coastal Plain Cooters sold as pets (or for consumption) are wild specimens that have been hunted or captured. Many states now list this species as protected, which is helping preserve the remaining population.

 


#8. Suwannee Cooter

  • Pseudemys suwanniensis

 

Identifying Characteristics:

  • 9 to 13 inches long. The record is 17.25 inches.
  • The carapace is completely black when dry, faint pattern shows when wet.
  • The plastron is yellow with some orange.

 

The Suwannee Cooter is the largest cooter turtle in Florida, and in fact, the largest in the world!

It is only found in Florida, and its habitat includes coastal wetlands, bays, and lagoons, and it is occasionally found far into the Gulf of Mexico. The diet of the Suwannee Cooter is mainly aquatic plants including swamp grass and algae.

Suwannee Cooter Rangemap

 

You are most likely to spot a Suwannee Cooter at dusk or dawn, because this is when they are most active. They spend these hours foraging and the rest of the day they bask in the sun on logs or rest on the bottom of bodies of water.

 


#9. Peninsula Cooter

  • Pseudemys peninsularis

Identifying Characteristics:

  • 9 to 13 inches long.
  • Light, thin lines on the top of the head and carapace.
  • The plastron is pale yellow and usually unmarked.

 

The Peninsula Cooter is ONLY found in Florida!

Its habitat is lakes and canals in Florida and it is sometimes also found in the Everglades. It is a close relative of the Coastal Plain Cooter, and some scientists consider it a subspecies.

You might have trouble identifying this species from other cooter turtles, because of how similar in appearance it is. The thin, light lines on its top shell and head, sometimes called hairpins, are a good clue that you have found a Peninsula Cooter!

 


#10. Florida Red-Bellied Cooter

  • Pseudemys nelsoni

Identifying Characteristics:

  • 8 to 12 inches long.
  • The plastron is reddish in color, and the carapace also tends to have some red coloring on an olive green base.
  • The head has an arrow-shaped marking, with the tip pointing toward the snout.

 

The Florida Red-Bellied Cooter is found in streams, ponds, and ditches in Florida. Occasionally, you might find one in brackish water.

 

Female Florida Red-Bellied Cooters are especially brave – they “borrow” the nests of alligators and lay their eggs inside!

Then, the female alligator does double-duty, protecting her own eggs as well as the turtle eggs!

 


#11. Pond Slider

  • Trachemys scripta

Identifying Characteristics:

  • 5 to 8 inches long.
  • The carapace is usually patterned with concentric rings, with red, olive to green, black, and brown sections.
  • Yellow to orange markings on the belly and sides are almost always present.

 

The native habitat of the Pond Slider is lakes, ponds, rivers, and streams. It prefers water with plenty of logs, branches, or vegetation to bask on and often can be seen in large groups.

Pond Slider Rangemap:

The Pond Slider, specifically the subspecies Red-Eared Slider, is the most widely introduced turtle in the world.

 

This species is commonly purchased as a pet and then released into the wild when it gets too large or difficult to take care of. Unfortunately, they can cause damage and put pressure on natural ecosystems.

 

The Red-Eared Slider is also commonly mistaken for the Painted Turtle because of its red marking at the jawline and brightly colored stripes. However, the carapaces of sliders are much more rounded and helmet-like, and they commonly get larger than Painted Turtles in captivity.

 


#12. Spiny Softshell Turtle

  • Apalone spinifera

Identifying Characteristics:

  • Females are 7 to 21.25 inches long; males are 5 to 12.25 inches long.
  • The carapace is flexible with a rough sandpaper texture, with a single row of spines or cones along the middle of the back. There is also a row of pointed tooth-like appendages on the edge of the carapace.
  • Coloring is olive, gray, or brown with black spots on some individuals.

 

Look for these turtles in the Florida panhandle in lakes, rivers, and streams with sandy or muddy bottoms and little or no vegetation. I often see them sunning themselves on the banks while kayaking down slow-moving rivers.

Spiny Softshell Turtle Rangemap:

 

Spiny Softshell Turtles will eat anything in the water they can swallow, including insects, crayfish, and even small fish! To catch a meal, this species buries itself in mud or sand with only its head uncovered and grabs its food as it swims by.

 

Spiny Softshell Turtles can “breathe” underwater by absorbing oxygen through the skin of their throats. This is a useful adaptation because they spend very little time out of the water, even sunning themselves in shallows or floating on the surface.

 

Along with the ability to absorb oxygen through its skin, the Spiny Softshell Turtle has some other unique adaptations that make it perfectly suited for its environment. Its leathery shell is extremely flat, and it has webbed feet and long claws, which allow it to swim quickly away from predators and bury itself in the muddy bottom.

 

Its most unique feature is its nose, which is long and snout-like! It can poke its nostrils out of the water and stay completely submerged to protect itself from hungry predators!

 

A closely related and almost identical-looking species, the Florida Softshell Turtle (Apalone ferox), shares the same habitat preferences as the Spiny Softshell Turtle. It has a much more limited range, and is usually slightly larger than its close cousin.

 


#13. Smooth Softshell Turtle

  • Apalone mutica

Identifying Characteristics:

  • Females are 6.5 to 14 inches long; males are 4.5 to 10.5 inches long.
  • The coloring of the carapace is gray to olive. Females have dark gray to brown or olive mottling.
  • The carapace is rubbery and smooth, with no spines or projections on the back.

 

Smooth Softshell Turtles prefer larger, fast-running rivers, but they can also be found in lakes and large ponds. They are particularly susceptible to damage caused by polluted water and face habitat threats because of this.

Smooth Softshell Turtle Rangemap:

On land, they are the fastest turtle in Florida!

 

Though most people assume that all turtles are slow-moving, the Smooth Softshell Turtle must be quick to outrun predators since its soft shell doesn’t provide much protection. Seriously, you need to look at this video to see just how fast they can run!

 

It is also a very strong swimmer and can move through the water at up to 12 miles per hour!

 


#14. Eastern Mud Turtle

  • Kinsternon subrubrum

Identifying Characteristics:

  • 2.75 to 4.75 inches long.
  • The carapace is smooth, with black or olive coloring. The belly is yellowish-brown, sometimes with black or dark brown markings.
  • Hatchlings have a rough carapace with more coloring that fades as the turtle grows.

 

Eastern Mud Turtles live in Florida in shallow water, such as ditches, wet meadows, marshes, and swamps. As their name suggests, they prefer muddy, silty-bottomed water over sandy or gravelly.

Eastern Mud Turtle Rangemap:

 

Because the Eastern Mud Turtle is small and nondescript, with no unique markings, it can be hard to identify. One feature that sets it apart from other species is the hinges on its lower shell, called a plastron, and forms two “K” shapes when viewed from the side. To see what I am talking about, take a look at the video below!

 

Unlike most other turtles, the Eastern Mud Turtle does not hibernate during cold winter months. In fact, it does the opposite! Instead, these turtles become dormant during the hottest part of the year! This is called estivation.

 


#15. Florida Mud Turtle

  • Kinosternon stendachneri

 

Identifying Characteristics:

  • 3 to 4 inches long.
  • The carapace is smooth and olive to almost black.
  • The plastron is yellowish with black and brown markings.

 

The Florida Mud Turtle is ONLY found in the Florida peninsula! It is considered a very close relative of the Eastern Mud Turtle, and was only classified as its own species in 2013.

Unlike most other turtles, the male Florida Mud Turtle is generally larger than the female.

 


#16. Striped Mud Turtle

  • Kinosternon baurii

Identifying Characteristics:

  • 3 to 4 inches long.
  • The carapace is generally dark brown or black with three light lines.
  • Young Striped Mud Turtles have a keel, or ridge along the spine, that flattens with age.

 

The Striped Mud Turtle prefers smaller, shallow bodies of water for its habitat. You are likely to see one in cypress swamps, drainage canals, and even ditches in Florida.

Striped Mud Turtles may also be easier to spot than other mud turtles because they spend more time on land than any other! They forage for insects, sun themselves, and rest out of the water, which is very unusual for mud turtles. 

 


#17. Eastern Musk Turtle

  • Sternotherus odoratus

Identifying Characteristics:

  • 2 to 4.5 inches long.
  • The head features two light stripes set on very dark brown or black skin.
  • The carapace can range from light olive to almost black, with irregular black markings.

 

The habitat for these turtles in Florida is slow-moving, sluggish streams and still bodies of water. It prefers areas with dark crevices where it can hide, and lots of plant matter to burrow in.

Eastern Musk Turtle Rangemap:

 

If you happen to disturb an Eastern Musk Turtle, it probably won’t take you long to identify it. As its name suggests, when threatened, they emit a foul, musky odor. This scent can be detected on land, in water, and even waft through the air to ward off predators.

 

In fact, in other areas, they are even known by another name – Stinkpot!

 

Another unique feature of the Eastern Musk Turtle is that it can climb trees! Individuals have been observed fairly high up in the branches. They climb to avoid predators and find a safe place to rest.

 


#18. Loggerhead Musk Turtle

  • Sternotherus minor

Identifying Characteristics:

  • 3 to 4.5 inches long.
  • The carapace is dark and often streaked, spotted, or blotched with yellowish-tan.
  • Older male specimens have extremely large heads in relation to their bodies.

 

The Loggerhead Musk Turtle is the most recognizable musk turtle in Florida! Its large head and beak-like mouth set it apart from many other turtle species – if you see one in the wild, it will be easy to tell what you’re looking at!

Loggerhead Musk Turtles prefer springs and streams with muddy bottoms, where they rest and forage for food.

 


#19. Spotted Turtle

  • Clemmys guttata

Identifying Characteristics:

  • 3.5 to 4.5 inches long.
  • The coloring of the carapace is olive to dark brown with light yellow spots.
  • The head and neck have irregular yellow or orange spots and streaks.

 

Spotted Turtles prefer shallow marshes, bogs, and swamps. They are equally comfortable on land as it is in the water.

The population of these turtles in Florida is declining rapidly due to habitat loss and human interference. Because of their unique shell patterns, Spotted Turtles are often removed from their habitat and sold as pets. As a result, they are listed as an endangered or protected species by many governing bodies.

 

In the wild, Spotted Turtles are aggressive hunters and will seek out live prey such as worms, slugs, millipedes, and spiders. They are also extremely smart! Studies using mazes have concluded that the Spotted Turtle has the same brain capacity as a mouse!

 

In the video below, you can see their unique pattern!

 


#20. Chicken Turtle

  • Deiochelus reticularia

Identifying Characteristics:

  • 4 to 6 inches long.
  • Coloring is brown to black, with yellow or orange spots on the sides of the head.
  • The neck is the longest of all North American turtles, except for soft-shell species.

 

Chicken Turtles are one of the most social turtles in Florida!

 

They often swim or bask in groups and rarely travel or live alone. It’s most common to see groups of Chicken Turtles basking in the sun, as most of their other activity such as feeding and reproduction, happens underwater.

 

The preferred habitat of Chicken Turtles in Florida is still water, such as ponds, ditches, or marshes. However, they are frequently seen on land, where they forage for food and bask in the sun.

Chicken Turtle Rangemap:

 

I was surprised to find out that Chicken Turtles were named because of the taste of their meat, which was a popular delicacy in the 1970s! Unfortunately, they are now an endangered species because of this popularity, though efforts have been started to protect the remaining population.

 

To see an example of how long their necks are, take a look at the video below!

 


Box Turtles in Florida:

As you’ll read below, a couple of species on this list are not box turtles. Because they’re also land dwellers, I have included them here. Hopefully, you will find them as interesting as I do!


#21. Eastern Box Turtle

  • Terrapene carolina

 

Identifying Characteristics:

  • 4.5 to 6 inches long.
  • The carapace is high and domed, usually with a ridge along the center running from head to tail.
  • Coloring is highly variable, but a pattern of olive, browns, and tans is almost always present.

 

The Eastern Box Turtle can live for over 100 years under the right conditions!

 

A typical lifespan for one in the wild or captivity is about 35 years. But in an optimal enclosure, one could live for much longer without the threat of predators or man-made hazards.

 

In northwestern Florida, the habitat of the Eastern Box Turtle includes woodland areas and dense thickets. It prefers areas with lots of access to sunlight and food sources nearby.

Eastern Box Turtle Rangemap:

 

The vivid designs and relatively easygoing nature of Eastern Box Turtles make them attractive as pets; unfortunately, this contributes to their decline in population. These turtles require very specific conditions to thrive in captivity. Special UV lighting, large tanks with fresh, clean water, vitamin and mineral supplements, and relatively deep substrate to burrow are just some of the requirements to keep them healthy as pets.

 

Because box turtles are often taken from the wild in Florida for the pet trade, most states have prohibited the capture and sale of this species. Unfortunately, many pet turtles die due to poor conditions or are abandoned because they are too hard to care for.

 

The markings of the Eastern Box Turtle are so variable you may have a hard time recognizing one by the shell alone! Some have lines running from the center of each scute, and some have rings of dots that form a lace-like pattern. Other individuals’ lighter markings can merge so that the carapace is almost completely light-colored instead of the usual dark background! The video below demonstrates the huge variability!

 

Many people believe that the vivid coloring on the shell of the Eastern Box Turtle fades with age, but this is incorrect. The shell of most box turtles in captivity fades over time due to lack of natural sunlight!

 


#22. Florida Box Turtle

  • Terrapene bauri

 

Identifying Characteristics:

  • 5-6.5 inches long.
  • The carapace is high and dome-shaped, with broken, irregular light lines and a dark brown background.
  • Usually, there are three toes on the back legs instead of the usual 4.

 

The Florida Box Turtle lives in wetlands, marshes, and swampy areas with heavy rainfall. It prefers wet environments with plenty of water nearby but will live most of its life on land where it eats many species of plants as well as animal prey. It prefers fleshy fruit such as low-hanging berries, and gastropods like snails.

Florida Box Turtle Rangemap:

Even though it likes water, this species rarely enters the water deep enough to swim!

 

Unlike most box turtles who only lay one clutch of eggs in a season, the Florida Box Turtle can nest up to FOUR times a year! The average size of a nest is between 1-9 eggs.

 

Even with this prolific breeding adaptation, the overall population of the Florida Box Turtle is in danger and considered threatened. Automobile accidents, habitat loss, and predation are leading causes of the declining population of this species.

 


#23. Gopher Tortoise

  • Gopherus polyphemus

 

Identifying Characteristics:

  • 6 to 9.5 inches long.
  • The carapace is brown or tan, with grayish-brown skin that has orange or yellow blotches.
  • Growth rings are easy to see in young individuals, but in older tortoises, the carapace is very smooth.

 

The Gopher Tortoise is the ONLY tortoise in Florida!

 

Gopher Tortoises live in sandy areas where burrowing into the soil is easy. They are scavenging herbivores and consume a variety of plants as long as they are easily accessible.

Gopher Tortoise Rangemap:

 

Gopher Tortoises face the threat of a declining population due mostly to human development of their habitat. You may even come across Gopher Tortoise Crossing signs, which are part of an effort to protect this species! In Florida, rules and regulations limit land development containing Gopher Tortoises or their burrows, and it is illegal to relocate them without permission from Fish and Wildlife services.

 

The Gopher Tortoise makes extensive burrows in the sandy soil, which are used as shelter by up to 360 other species. Most notably, Gopher Tortoises often share their burrows with Eastern Diamond-backed Rattlesnakes!

 

Check out the video below to get a close look at a Gopher Tortoise burrow!

 

 


Sea Turtles in Florida:

Because of their migratory nature and ability to range far into the ocean, sea turtles are not truly “native” to one part of the world. The sea turtle species below can be seen on the coast of Florida.


#24. Green Sea Turtle

  • Chelonia mydas

 

Identifying Characteristics:

  • Weighs 150-420 lbs. and is 30 to 60+ inches long. However, some individuals have been recorded much larger, more than 600 lbs!
  • The carapace is smooth, with 4 sections on each side.
  • Coloring is olive, brown, or gray. Its name refers to a layer of green body fat found under its shell.

 

Green Sea Turtles live in coastal lagoons and bays throughout Florida. Incredibly, they rarely come to shore except to lay their eggs, preferring to spend most of their time in the water. They are actually tough animals to see because they are extremely fast swimmers and prone to hiding or fleeing with any signs of danger.

Did you know Green Sea Turtles use the Earth’s electromagnetic waves?

 

In a process known as Natal Homing, these incredible turtles use magnetic crystals in their brains to read the magnetic waves coming from the Earth. They use this information to find the specific beach where they were hatched to lay their own eggs! Though it sounds like science fiction, it’s a common mechanism in many sea turtles.

 

One of the most concerning threats to Green Sea Turtle populations is climate change.

 

The warming of seawater is changing the migration & nesting pattern of the turtles. Interestingly, the sand temperature changes resulting from climate change also affect the ratio of male to female turtles, which can cause changes in breeding patterns and decreased hatch populations. Poaching, bycatch, nesting site loss, and disease are the other top threats to Green Sea Turtles.

 


#25. Loggerhead Sea Turtle

  • Caretta caretta

 

Identifying Characteristics:

  • The average weight is 300 lbs. and 35 inches long. Record Loggerhead Sea Turtles have reached over 1,000 lbs!
  • The carapace coloring is red to orange-brown, edged in yellow. The belly is cream to dusky beige.
  • The Loggerhead’s carapace sections are much more pronounced than any other sea turtle.

 

The Loggerhead Sea Turtle gets its name from its large, blunt head!

 

It uses its powerful jaws to feed on much harder prey than other sea turtles, such as whelks, conch, and other hard-shelled invertebrates.

 

In Florida, Loggerhead Sea Turtles are rarely seen, mostly because they live where people typically never visit. They love open oceans and can swim great distances between breeding seasons.

Loggerhead Sea Turtle Rangemap:

The largest nesting population of Loggerhead Sea Turtles is right here in the USA! Unfortunately, most other nesting populations, such as ones in the Caribbean and Japan, have seen a recent steep decline – up to 90% of the total nesting population has declined in these regions. Part of the reason for the steep decline is that Loggerhead Sea Turtles don’t reach reproductive maturity until age 35!

 

The most concerning threat to Loggerhead Sea Turtles in Florida is bycatch. This happens when they are unintentionally caught in a net or trap meant for fish or shrimp, which can cause the turtles to drown or be severely injured when they try to free themselves.

 

Loggerhead Sea Turtles have an interesting way of keeping their shells healthy. They allow fish to “clean” them by eating the barnacles and other parasites that live in their shells!

 


#26. Leatherback Sea Turtle

  • Dermochelys coriacea

 

Identifying Characteristics:

  • Weighs 600 to 6,000 lbs and is 48 to 96 inches long.
  • The carapace is made of flexible, leathery skin, and the coloring is black to slate gray.
  • The sections of the carapace are diamond-shaped, stretching the length of the body.

The Leatherback Sea Turtle is the largest sea turtle, not only in Florida, but in the world!

 

It ranges all over the world into every ocean but prefers temperate to cooler water during most of its life. Leatherback Sea Turtles are highly migratory and will travel up to 10,000 miles per year between foraging and nesting grounds! Its hatching grounds in the USA range along the western coastline.

Leatherback Sea Turtle Rangemap:

Like most sea turtles, Leatherback Sea Turtles face severe population decline and are listed as endangered in most countries. One of the primary threats to Leatherback Sea Turtles is the collection of their eggs for human consumption. Even though they are a protected species in most countries, poaching and illegal collection are still common.

 

One of the most interesting features of the Leatherback Sea Turtle is its speed; even though it is the largest living sea turtle, it’s also the fastest. Swimming speeds of nearly 22 miles per hour have been recorded! It uses this speed to travel great distances, often traveling over 3,600 miles between nesting and foraging grounds. Considering their size, they’re pretty fast on land too!

 


#27. Kemp’s Ridley Sea Turtle

  • Lepidochelys kempii

 

Identifying Characteristics:

  • Weighs 80 to 100 lbs and is 23 to 28 inches long.
  • The carapace is nearly circular when seen from above, and usually a uniform olive green. The belly is yellowish.
  • Young Kemp’s Ridley Sea Turtles are a uniform purple all over.

 

Kemp’s Ridley Sea Turtles live in the Gulf of Mexico and the Atlantic Ocean and can be found along the eastern coastline. They prefer shallow water with a sandy or muddy bottom.

This species is the smallest sea turtle in Florida!

 

Their size may be one reason they have a unique nesting strategy called arribada, where many nesting females gather offshore and come out of the water together, nesting in a tight group. Arribada nesting can help the nesting mothers protect each other from predators, and also helps more hatchlings make it to the open ocean.

 

Due to habitat loss, pollution, and injuries from fishing nets, Kemp’s Ridley Sea Turtles are the most critically endangered sea turtle species. Currently, their estimated nesting female population is less than 250 individuals. Intensive conservation efforts are underway, but populations have not increased since about 2010.

 

These sea turtles are particularly susceptible to casualties from oil spills. For example, almost all of the 156 sea turtles that died and 456 that were rescued from the Deepwater Horizon disaster were Kemp’s Ridleys.

 


#28. Hawksbill Sea Turtle

  • Eretmochelys imbricata

 

Identifying Characteristics:

  • Weighs 95 to 165 lbs and is 30 to 35 inches long.
  • The carapace coloring is amber with irregular light and dark streaks. The coloring changes slightly with water temperature.
  • Hawk-like, hooked beak.

 

Hawksbill Sea Turtles get their name from their hooked beak, which they use to reach into small crevices and pull out their prey. They primarily eat sea sponges but also prey on small fish, jellyfish, mollusks, and crustaceans.

 

The Hawksbill Sea Turtle lives in lagoons and coral reefs in the oceans around the world, preferring tropical and subtropical climates. It spends part of its life in the open sea but frequently returns to shallower water. In Florida, Hawksbill Sea Turtles spend much of their time foraging in coral reefs.

Hawksbill Sea Turtles are critically endangered due mostly to exploitation and consumption by humans. Commonly, “tortoiseshell” accessories and items are made from the shell of the Hawksbill, and while killing them is now illegal in most countries, poaching is still a serious threat. The threat of poaching is made worse because they only nest once every 1-5 years, much less than most other sea turtles.

They are the only sea turtle that prefers to nest on rocky beaches instead of the sand!

 

Hawksbills search for “pocket” beaches, small coves, or inlets surrounded by rocks when nesting. They travel high up the beach and lay their eggs in the shelter created by plants.
