6 Venomous Snakes Found in Venezuela (2025)
What types of venomous snakes live in Venezuela?
Due to the variety of habitats in Venezuela, there are dozens of different snakes you might see. While many species are not harmful to humans, you must be careful because some types are INCREDIBLY venomous and highly dangerous. Some snakes can even cause death if the bite is not treated quickly.
In the article below, I have listed some of the most common venomous snakes you might encounter in Venezuela. For each species, you will find out how to identify that snake correctly, along with pictures and interesting facts!
*If you come across any of these species, PLEASE DO NOT DISTURB! Venomous snakes are dangerous animals and should be left alone. The more you agitate them, the more likely you could get bitten. DO NOT RELY ON THIS ARTICLE to correctly identify a snake that has recently bitten you. If you have recently been bitten, GO DIRECTLY to the nearest hospital to get help and to determine if the snake is venomous.*
6 Venomous Snakes in Venezuela:
#1. Fer-de-lance
- Bothrops atrox
Also known as Common Lancehead, Barba Amarilla
Identifying Characteristics:
- Adults can grow 75-125 cm (30-49 in) in length.
- Look for a series of trapezoids across the body.
- Coloration is usually olive, gray, or brown. They have light-colored bellies, commonly white or cream.
- These snakes have golden irises and black tongues.
The venomous Fer-de-lance is responsible for most of the snake bites in Venezuela.
So, it’s best to tread carefully if you find yourself in the Amazon region. While these snakes live primarily in dense forests, they also wander into coffee plantations when hunting.
As with other pit vipers, the Fer-de-lance has heat sensors below its eyes to track prey. They easily devour smaller prey like frogs and tarantulas. However, when it comes to larger prey, these snakes bite and then let go. The venom eventually kills the animal while the snake tracks it down to consume it.
This snake isn’t only dangerous to its prey, either. A bite from this venomous snake targets the circulatory system and can cause serious internal bleeding in humans. Interestingly, the younger snakes have faster-acting venom. Either way, you should seek medical attention quickly if you get bitten by this aggressive species.
#2. Terciopelo
- Bothrops asper
Identifying Characteristics:
- On average, these vipers are 120-180 cm (47-71 in) long.
- Terciopelos have wide, flat heads.
- Females can grow up to 10 times larger than males.
- They range from brown to gray. Patterns include dark spots and stripes that form triangles along the body.
The Terciopelo, which is also referred to as a Fer-de-lance in its range, is a venomous species you can find in tropical rainforests and lowlands. They have a fierce reputation and are responsible for many of the snakebites that occur in Venezuela. They also have large fangs and an exceptionally high venom yield. This snake is impressive but also terrifying and has been nicknamed “the ultimate pit viper”!
This large pit viper is a patient predator. It will disguise itself among leaf litter for long periods, then bite swiftly once prey comes in range. The Terciopelo’s usual meal includes various insects, rabbits, and crayfish.
The venom of a Terciopelo is dangerously potent. Unfortunate victims can experience fevers, internal bleeding, and even death in extreme cases. It’s important to seek medical attention immediately if you think you’ve been bitten. If the Terciopelo is cornered, it will strike faster than you can react. So always keep a respectful distance!
#3. Mountain Keelback
- Helicops angulatus
Also known as Brown-banded Watersnake, Water Mapepire
Identifying Characteristics:
- Adults grow to a maximum length of 78 cm (31 inches).
- Their eyes and nostrils are situated at the top of their heads.
- These snakes tend to be olive or grayish brown. Dark, jagged bands cover their bodies.
The Mountain Keelback is one of the slowest venomous snakes in Venezuela!
These sluggish travelers only move about a few meters each day. If you want to find one in action (or non-action, because of their slow speed), look in the freshwater bodies of the Amazon basin.
Because of its slow-moving nature, this species prefers to ambush unsuspecting prey. At night, Mountain Keelbacks lie in wait for unlucky animals swimming by. Smaller fish, frogs, and tadpoles are all on the menu. However, sometimes they are the unlucky ones as they are common prey for herons and larger snakes.
Mountain Keelbacks are only mildly venomous. However, they can be very irritable when disturbed. In defense, they will coil into an S position before lunging into a bite. They can’t kill you, but their bites are still quite painful. Hands off!
#4. Neotropical Rattlesnake
- Crotalus durissus
Also known as South American Rattlesnake, Central American Rattlesnake, Cascabel Rattlesnake, Guiana Rattlesnake, Aruba Island Rattlesnake
Identifying Characteristics:
- Adults are typically 150 cm (59 in) long on average.
- There is a prominent stripe at the base of their heads, intersecting each eye.
- Scales protrude from their body.
- They usually appear in shades of brown and gray. Sometimes, patterns of diamonds and triangles form across the body. Bellies are yellowish or white.
Neotropical Rattlesnakes in Venezuela are residents of grasslands and tropical forests.
You might also find them in drier areas if a shortage of prey drives them to find food. These snakes are most active at dusk, stalking rodents and other reptiles. They’re equipped with heat-sensing pits below their eyes to track down prey.
These rattlesnakes are dangerously venomous. Left untreated, bite victims can experience muscle paralysis and difficulty breathing. In the worst cases, victims can end up with organ failure and death. Therefore, if you receive a bite from a Neotropical Rattlesnake, it’s vital to get medical help as soon as possible.
A Neotropical Rattlesnake can move with remarkable speed, but its first instinct is not to attack. To warn you, it might make a rattling sound with its tail or raise its forebody into a defensive striking posture. When this happens, it’s best to respect the warning, back away slowly, and then leave the area.
#5. South American Bushmaster
- Lachesis muta
Also known as Atlantic Forest Bushmaster, Mapepire Zanana
Identifying Characteristics:
- Adults are 200-250 cm (79-98 in) long.
- They have broad heads.
- Their coloring can be yellowish, tan, or gray-brown.
- Look out for a scaly diamond pattern and a pale-colored underside.
True to its name, the South American Bushmaster loves to hide in the bushes and undergrowth of forests with frequent rain. This stealthy snake lurks near animal trails, waiting to ambush rodents, birds, and other smaller reptiles.
Bushmasters are solitary creatures. In fact, they are so elusive that herpetologists are still arguing about how dangerous they are. When they’re not hunting, these pit vipers rest in hollow logs and small burrows. So, don’t go peeking inside unless you’re prepared to come across one!
Loud rustling among fallen leaves can indicate the presence of a South American Bushmaster. They usually try to escape if disturbed but stay cautious nonetheless! Most researchers agree that they’re highly venomous. Untreated bites are thought to be potent enough to kill.
#6. Redtail Coral snake
- Micrurus mipartitus
Identifying Characteristics:
- Adults are 60-89 cm (24-35 in) long.
- They have thin, cylindrical bodies, small heads, and short fangs.
- Their coloring is black and yellow or white alternating bands, and they have red heads and black snouts.
Redtail Coralsnakes prefer mountains and rainforests with dense vegetation. Occasionally, you might see them in coastal shrub areas and dry, rocky regions.
Unlike most venomous snakes in Venezuela, this one is semi-fossorial.
This means they spend most of their time underground or burrowed in the foliage of the forest floor. Here, they feed on other reptiles and amphibians. They prefer smaller prey as they swallow meals whole and have small mouths.
Although Redtail Coralsnakes are timid and nocturnal, they will strike if surprised, and their venom is highly toxic. Most encounters are with agricultural workers. If left untreated, a victim can suffer paralysis, respiratory arrest, and even death.
