You’ll see that the venomous snakes in Angola 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 Angola:
#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 Angola.
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 Angola, 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 Angola 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.
- Dispholidus typus
Also known as Common African Tree Snake, Kivu Boomslang, and Kivu Large Green Tree Snake
- Adults are usually 100-160 cm (39-63 in) long.
- Coloration varies greatly, allowing these snakes to camouflage in different terrains.
- Generally, males are light green, scaled with black and blue, and females are brown.
- Boomslangs have an egg-shaped head and notably large eyes.
This slender venomous snake makes its home in low-lying trees in Angola.
In fact, its common name, “Boomslang,” means “tree snake” in Afrikaans and Dutch. Be careful within this species’ range because the next vine you pull might become a deadly encounter!
This snake’s venom is highly potent, causing bleeding and death for humans, even in small doses. However, compared to front-fanged snakes, which release large amounts of venom at once, rear-fanged snakes like the Boomslang inject small amounts of venom in quick succession.
When confronted, the Boomslang will freeze and then swing its head from side to side before quickly attacking. Fortunately, Boomslangs won’t attack humans except as a last resort. If you are bitten, seek immediate treatment. Victims might get a false sense of safety because the venom is slow-acting, but many people have died from internal bleeding hours later.
#5. Gaboon Viper
- Bitis gabonica
Also known as Gaboon Adder, Forest Puff Adder, Butterfly Adder, Whisper, Swampjack
- Their typical size is 80–205 cm (31-81 in) long.
- Females are heavy and stout, while males have longer tails in proportion to their body length.
- You’ll see faded, rectangular blotches down the snake’s back, with yellowish hourglass-shaped marks along the gaps.
The Gaboon Viper boasts the longest fangs of any venomous snake in Angola!
Incredibly, they can grow up to 6 cm (2.3 in) long. This is one snake you definitely want to steer clear of!
Interestingly, its fangs aren’t the only unusual thing about this species. It also has the highest venom yield of any snake worldwide because of its hunting style. Unlike most vipers, it doesn’t release once it engages in a bite, injecting massive amounts of venom into its prey.
Watch your step because this nocturnal viper has near-perfect camouflage. It’s practically invisible amid fallen leaves on the forest floor and can remain motionless for hours hunting small birds and mammals.
The Gaboon Viper’s venom can be fatal in large doses or cause severe necrosis in the bite area. Fortunately, bite incidents are rare. These snakes are normally non-aggressive, sluggish, and are only encountered in dense rainforests.
#6. Black Mamba
- Dendroaspis polylepis
- Adults are 200-450 cm (79-177 in).
- Its coloring is usually brown, olive green, or yellow. Black specimens with purplish scales are very rare.
- Juveniles are usually gray or green, but they darken with age.
In small woodlands and rocky outcrops lurks what many consider the deadliest venomous snake in Angola, if not the world. The Black Mamba is named after the inky coloring of the inside of its mouth, something you should hope never to see! It likes to nest in burrows, so stay alert around suspicious holes.
The fatally potent venom of the Black Mamba targets the nervous system and the heart. Difficulty breathing can occur within 10 minutes. If you get bitten, it’s a race against time, so get medical attention immediately!
In addition to their highly toxic venom, Black Mambas are terrifyingly fast. They can move 16 kph (10 mph) for short distances and even lunge at prey or attackers.
Contrary to popular belief, these snakes are rather shy and will choose to escape when given a chance. They raise their heads, spread their cobra-like neck hoods, and hiss loudly to warn would-be attackers. So the best thing to do if you encounter the Black Mamba is to slowly back away, making sure it doesn’t feel cornered.
#7. Black-necked Spitting Cobra
- Naja nigricollis
- 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 Angola 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.
#8. 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 Angola, 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.
#9. Cape Coral Snake
- Aspidelaps lubricus
Also known as Coral Shield Cobras and Cape Coral Cobras.
- Adults are 45-76 cm (18-30 in) long.
- They have a narrow neck hood and a short head.
- Their coloring is usually red-orange to yellow with thick black rings down the length of their bodies.
Look for this venomous snake in Angola in dry habitats.
You’re most likely to find them in arid deserts and other sandy or rocky ecosystems with little vegetation besides scattered shrubs.
In these intense climates, Cape Coral Snakes are nocturnal out of necessity. Most of their activity and hunting occurs after the sun has gone down. During the day, they stay cool in the shelter of burrows, tunnels, and rocks. They prefer cooler nights and move around less during the heat of summer.
When they leave the burrow in the evening, the hunt is on. Cape Coral Snakes rely on their sense of smell and taste rather than sight. Typically, they go for diurnal prey that’s asleep, which makes an easy target. Lizards, legless skinks, small rodents, and occasionally other snakes are all on the menu. Before feeding, they strike their prey and inject venom to incapacitate it.
When threatened, Cape Coral Snakes flatten their neck like a cobra, hiss at their attacker, and strike repeatedly. Unfortunately, fatalities from their bites have been recorded! It’s thought that their neurotoxic venom causes respiratory failure.
#10. Twig Snake
- Thelotornis capensis
Also known as Cape Twig Snake, Savanna Vine Snake, Southern Bird Snake, Cape Twig Snake
- These are slender snakes with very long tails, measuring 100-168 cm (39-66 in) in total length.
- Look for a flattened bluish-green head, keyhole-shaped pupils, large black fangs, and a reddish-black tongue.
- Body coloration is brown or gray with blotches.
As the name suggests, you might mistake this venomous snake in Angola for a twig!
Twig Snakes hang perfectly still on branches of low shrubs, waiting for passing chameleons, frogs, and birds. They are patient predators and can maintain this posture for hours. When disturbed, they inflate their necks like a balloon as a scare tactic.
Take great care when trekking through coastal forests and woodlands. Its coloration allows it to blend in with the bark and branches of trees. Although it’s unassuming, the Twig Snake is venomous and very dangerous.
The Twig Snake’s venom is a slow-acting poison that can cause profuse bleeding and hemorrhage. One German herpetologist, Robert Mertens, died 18 days after being bitten by his pet Twig Snake. So, get quick medical treatment for a bite even if you don’t have immediate symptoms.
#11. Horned Adder
- Bitis caudalis
- Adults are 30-50 cm (12-20 in) long.
- They have short, stout bodies, keeled scales, and large horn-like scales over each eye.
- Their coloring varies over their range. They may be gray, brown, yellow, or reddish-orange, with darker blotches down their backs.
You can find Horned Adders in sparsely vegetated and semiarid scrub, but they are tough to spot! The coloring of these unusual snakes typically matches the sand in their area, giving them perfect camouflage. Interestingly, males are more brightly colored than females, while females are typically larger than males.
Horned Adders live in areas with brutally hot daytime temperatures, so they seek shelter during the day. They take advantage of their incredible camouflage and bury themselves in loose sand or rest in the shade of a rock or bush. Then, at dusk, as temperatures drop, they come out to hunt, preying on lizards, geckos, small mammals, and birds.
When threatened, the already fierce-looking Horned Adder puts on an intimidating display, puffing up its body and hissing. If approached, they will strike repeatedly and have cytotoxic venom, which causes swelling and pain. Thankfully the venom is relatively weak, and anti-venom isn’t typically required.
#12. Mozambique Spitting Cobra
- Naja mossambica
- Adults are 91-106 cm (36-42 in) long.
- Their back may be slate to blue, olive, or tawny black, while their underside is salmon-pink to purple-yellow with black bars on their throats.
- They have hoods on their necks, which they expand when threatened.
You’ll have to stay up late to find these venomous snakes in Angola.
Mozambique Spitting Cobras are nocturnal and terrestrial, hunting at night and spending most of their days hidden away in crevices, holes, and termite hills. But if you run into one, watch out! Mozambique Spitting Cobras are considered one of the most dangerous species in Angola.
Mozambique Cobras are nervous and quick to attack when they feel threatened. They rear up, lifting up to two-thirds of their body off the ground, spreading their hood, and spitting at their attacker’s eyes. They can spit 1.8-2 m (6-7 ft) with surprising accuracy. If their attacker gets close, they strike with a vicious bite.
Their venom contains both cytotoxins and neurotoxins. If the venom gets into a victim’s eyes, it can cause permanent damage and blindness. In addition, bites cause severe pain, swelling, necrosis, vomiting, respiratory distress, and dizziness. Without immediate medical attention, the symptoms can be deadly.
Mozambique Cobras are incredible predators that feed on birds, amphibians, eggs, small mammals, carrion, and other snakes. Most incredibly, these dangerous cobras will even attack the notorious Black Mamba and have developed an immunity to their venom.
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.”
