You’ll see that the venomous snakes in Benin are very different from each other. They have different sizes, habitats, and even different types of venom. In addition, certain snakes are common to find living around people. For each species, you will find out how to identify that snake correctly, along with pictures, interesting facts, and RANGE MAPS!
Venomous Snakes that Live in Benin:
#1. Puff Adder
- Bitis arietans
Also known as the African Puff Adder and Common Puff Adder.
- 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 Benin.
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. Jameson’s Mamba
- Dendroaspis jamesoni
- Adults are 1.2-2.1 m (4-7 ft) long.
- Their coloring is dull green mottled with black and yellow, and they have a cream underside.
Jameson’s Mambas are highly venomous snakes that primarily inhabit rainforests, woodlands, and savanna. They also use mango and nut plantations, parks, and farmlands and are occasionally found around buildings.
If you want to see this venomous snake in Benin, you may have to spend a long time searching. This shy species is primarily arboreal and spends most of its days in the dense vegetation of trees, hunting birds, lizards, bats, and small mammals. However, if you’re lucky (or unlucky), you may spot one on the ground as they bask or move between trees.
Jameson’s Mambas have a highly potent neurotoxic venom. Unfortunately, they are sometimes confused with common, harmless green snakes, which can be a deadly mistake. Without immediate treatment, this snake’s bite can kill a human within four hours!
Thankfully, they are generally not aggressive, and bites are rare. If confronted, their first instinct is to flee. They may also put on a threat display and flatten their neck to mimic a cobra.
#3. Spotted Night Adder
- Causus maculatus
Also known as Forest Rhombic Night Adders or West African Night Adders.
- 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 Benin 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.
#4. Forest Cobra
- Naja melanoleuca
Also known as Central African Forest Cobra, Black Cobra, Black and White-lipped Cobra
- A. Morph #1 (for forests): Glossy black body with broad cross-bars and blotches. There are black and white bars on the lips. The underside is white.
- B. Morph #2 (for savannas): The body has black and yellow bands with a black tail. The head, lips, and throat are yellow.
- C. Morph #3 (for coastal plains): Black body fades to brown towards the tail. The belly is creamy yellow and heavily speckled. Some specimens are completely black.
If you want to avoid this venomous snake in Benin, don’t go peeking around holes in the ground!
This DANGEROUS venomous species likes to nest in burrows. The Forest Cobra is HUGE, attaining lengths of 140-320 cm (55-126 in), and prefers living in wet woods. However, it adapts easily to drier environments as long as there’s access to a body of water.
These snakes eat a wide variety of food. Being semi-aquatic, they sometimes enjoy hunting for fish and amphibians. But they also spend time hunting rodents, lizards, and other snakes on land. However, tree-dwellers aren’t safe either. The Forest cobra will nimbly climb trees to eat insects and bird eggs.
A bite from a Forest Cobra delivers large quantities of highly potent venom, capable of killing a human within 30 minutes. Therefore, extreme caution is advised in the presence of this highly aggressive and dangerous snake.
#5. Green Bush Viper
- Atheris chlorechis
Also known as Western Bush Vipers or West African Leaf Vipers.
- Adults are about 50 cm (20 in) long.
- Their coloring is light green with a pale green underside and pairs of faint yellow spots running down their back about 2.5 cm (1 in) apart.
- They have slender bodies, triangular heads, and intensely keeled scales.
Look for this venomous snake in Benin in dense forests.
Green Bush Vipers spend most of their time in branches 0.9-1.8 m (3-6 ft) off the ground. Their coloring allows them to remain hidden amongst the foliage to avoid predators and ambush prey like rodents, lizards, and tree frogs.
While they’re not aggressive snakes, a bite from a Green Bush Viper can have serious consequences. Their venom can result in internal hemorrhaging and renal failure, which can be fatal if left untreated.
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.”
