Venomous Snakes that Live in Senegal:


#1. Puff Adder

  • Bitis arietans

Also known as the African Puff Adder and Common Puff Adder.

Types of venomous snakes in Senegal

Identifying Characteristics:

  • Adults are 100-150 cm (39-59 in) long.
  • They are commonly gray to dusty brown, with yellow chevrons on their backs.
  • There are two dark bands on the head, one on the crown and one between the eyes.
  • Male Puff Adders are usually larger than females.

Puff Adders are one of the most dangerous venomous snakes in Senegal.

This ill-tempered native snake roams savannas, grasslands, and – to the great misfortune of inhabitants – densely populated areas. The Puff Adder gets its name from how it inflates itself when threatened. Instead of moving away, it will hiss a warning to intruders before inflating and striking.

Its distinctive yellow, white, and brown chevron pattern allows the Puff Adder to blend into its surroundings. This camouflage is particularly useful for its lifestyle as an ambush predator. Be careful where you wander because this highly-venomous, fast-striking snake seems to come out of nowhere.

The Puff Adder’s venom contains a cytotoxin that can kill a healthy adult human within a day. Their potent poison and tendency to loiter around footpaths make this snake one to avoid. Watch your step!


#2. Spotted Night Adder

  • Causus maculatus

Also known as Forest Rhombic Night Adders or West African Night Adders.

Types of venomous snakes in Senegal

Identifying Characteristics:

  • Adults are 30-71 cm (12-28 in) long.
  • They are small, thick, and have broad, rounded snouts.
  • Their coloring is brownish, but they may also be gray, olive, or light green with dark brown or black patches down their back.

You can find these venomous snakes in Senegal in nearly every habitat!

They occupy forests, savanna, and semi-desert. Across this wide range of habitats, we also see a range of coloration. Some individuals may have different patterns, and especially in arid regions, they may have no pattern at all.

Despite the name, Spotted Night Adders are active during the day and at night. They move across the landscape slowly but can strike with incredible speed. Even though they’re a terrestrial or ground-dwelling species, they will occasionally pursue a frog or toad into a shrub.

While venomous, Spotted Night Adders don’t pose a serious risk to humans. Bites generally result in relatively mild symptoms, including pain, swelling, and mild fever. Typically the symptoms disappear within three days, but you should still see a doctor if bitten.


#3. Black-necked Spitting Cobra

  • Naja nigricollis

Types of venomous snakes in Senegal

  • A. Morph #1: Black or gray body with pink bars on the broad neck and a reddish belly.
  • B. Morph #2: Light brown or yellow body with no neck bands.
  • C. Morph #3: White and black stripes on the body or solid white with dark eyes.
  • The average length is 1-2 m (3-7 ft).

Look for these venomous snakes in Senegal near streams and rivers.

Black-necked Spitting Cobras are highly adaptable and can be active day or night. This far-ranging snake’s prey includes small vertebrates on the ground or bird eggs in trees.

When confronting possible threats, Black-necked Spitting Cobras rise from the ground and spread their impressive neck hoods. Then, true to their name, they will spit venom to blind their aggressors. Keep your eyes covered because these cobras have amazing aim and can hit their target up to 7 m (23 ft) away!

Black-necked Spitting Cobra bites can cause symptoms such as swelling, blistering, extreme pain, and loss of limb function. In worst-case scenarios, death may occur due to paralysis of the diaphragm.

Although it’s a different variety of spitting cobra, the video below shows the power of a spitting strike.

Did you know that snakes are considered venomous, NOT poisonous?

There currently is a common misconception between poisonous and venomous, one is ingested, and the other is injected. So, for example, If you eat something that makes you sick, then it is considered “poisonous.” But if an animal, like a snakes, delivers its toxins when it bites, then it’s considered “venomous.”
