Meet Gaboon viper, the snake with the longest fangs
Native to the rainforests and savannahs of sub-Saharan Africa, the Gaboon viper (Bitis gabonica) is often misunderstood and rarely seen — unless you happen to step too close.
If snakes had an invisibility cloak, this one would wear it best. The Gaboon viper's body is patterned in earthy browns, purples, and leaf-like designs, making it nearly impossible to spot among fallen foliage. It lies completely still, blending so well into its surroundings that even trained herpetologists have been known to miss it.
Its stillness isn't fear — it's strategy. The snake prefers ambush hunting: waiting for small mammals or birds to wander within range. And when they do, the strike is instant.
One of the most famous facts about the Gaboon viper is its fangs — which can grow up to 2 inches (5 cm) long, the longest of any venomous snake on Earth.
But the size does not matter. The snake delivers a large volume of potent cytotoxic venom, which breaks down tissue and causes serious damage. Fortunately, due to its calm temperament and remote habitats, human bites are rare.
This is not a snake that slithers away quickly. The Gaboon viper is built like a tank — thick-bodied and heavy, with adults often weighing over 8 kg (18 lbs) and reaching over 6 feet (1.8 m) in length.
It's not built for speed. It doesn't need to be. Its sheer power, camouflage, and lightning-fast strike make up for it.
Yes — but only if provoked or stepped on. The Gaboon viper's venom can be fatal without treatment, but this snake is far more interested in avoiding humans than harming them.
It's often stepped on accidentally because of its calm and sluggish nature. Most bites are the result of unfortunate surprises.
Antivenom exists, and fatalities are rare where medical access is available.
As an apex ambush predator, the Gaboon viper plays a key role in keeping rodent and bird populations in check. It's an important — and beautiful — part of Africa's forest ecosystem.
Sadly, like many species, it faces habitat loss due to deforestation and human encroachment.

Black mamba vs Gaboon viper: Which is Africa's deadliest snake on the basis of venom, size, habitat and more
Africa harbours some of the world's most lethal snakes, and two of its most formidable are the black mamba and the Gaboon viper. Though both inhabit parts of Sub-Saharan Africa, they differ greatly in appearance, behaviour, and how they kill. The black mamba is feared for its speed, aggression, and extremely fast-acting neurotoxic venom, while the Gaboon viper relies on camouflage and delivers massive doses of potent cytotoxins with the longest fangs in the snake world. This article compares the two in detail—analysing their hunting methods, venom effects, and threat to humans—to reveal which of these African giants is deadlier. Black mamba and Gaboon viper: Key differences explained Category Gaboon Viper Black Mamba Physical Size Thick-bodied; up to 7 feet long and 45 pounds; body width can reach 6 inches Long and slender; can grow up to 14 feet but only 4.5 pounds; built for speed and agility Venom Type Cytotoxic – destroys tissue, causes local damage; injects up to 600mg per bite Neurotoxic – attacks nervous system; injects up to 120mg per bite, enough to kill 10–20 people Venom Potency Highest venom yield per bite of any snake (up to 2,400mg in glands) Extremely potent venom; can kill in under an hour if untreated; 100% envenomation rate Fangs Longest venomous snake fangs: up to 2.2 inches; penetrates deeply and holds prey Shorter fangs: 0.5–0.8 inches; delivers venom through rapid multiple bites Camouflage and Build Broad head with leaf-like shape and horns on snout; blends with forest floor; slow, non-aggressive Slender, olive/gray/brown body; black interior mouth; fast and aggressive when provoked Habitat Prefers rainforests and dense woodlands; low visibility increases risk of accidental bites Found in savannahs, rocky hills, and open woodlands; wider range increases human encounters Lifespan (Wild/Captive) Lives around 10 years in the wild; up to 20 years in captivity Lives around 11 years in the wild; can exceed 20 years in captivity Black mamba vs Gaboon viper Physical size The Gaboon viper is a stout-bodied snake, with a reputation for being heavily built and very short compared to the black mamba. The longest it will get is 7 feet long, and at maximum weight, it reaches 45 pounds, with its body so wide that it will be about 6 inches in diameter. Conversely, the black mamba is designed for speed and agility. While it is much lighter—usually weighing no more than 4.5 pounds—it has the potential to reach a whopping 14 feet in length, one of the longest venomous snakes globally. Its slender, aerodynamic body enhances its high-speed attacks and quick movement. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 유일한 공식 무료 SOC 게임! 설치도 없습니다! 경복의 바다 게임 플레이 Undo Venom Both are fatal, but their venoms act differently. The Gaboon viper's venom is cytotoxic, or tissue-destroying, causing extreme local damage. Surprisingly, it injects more venom per bite than any other species—up to 600 milligrams per strike and storing up to 2,400 milligrams in its venom glands. The black mamba, however, yields neurotoxic venom, which targets the nervous system. It delivers as much as 120 milligrams with each bite, but its venom is so toxic that it can kill 10–20 individuals with one dose. Death can result in less than an hour without immediate treatment. Worse still, black mambas tend to bite repeatedly and achieve a 100% rate of envenoming, meaning almost any bite carries venom. Fangs Gaboon viper has the longest fangs among venomous snakes, with up to 2.2 inches in length. Long fangs enable deep penetration and maximum venom injection while biting and holding prey. Black mamba's fangs, while much shorter at around 0.5 to 0.8 inches, are still functional. Coupled with their quick, multiple-strike nature, they ensure efficient delivery of venom. Morphology and camouflage The Gaboon viper is a camouflage expert. Its dead-leaf-like coloration helps it hide in the dark forest floor without anyone noticing. The flat, leaf-like head and diminutive horns between the nostrils also contribute to the camouflage. It is basically a non-aggressive animal and only bites by mistake—mostly when human beings tread on it unconsciously. The black mamba, contrary to its name, is seldom black. It is often olive, gray, or brown, with a particular inky-black lining of its mouth, which it presents as a threat. Although not a cobra, it can also spread its neck slightly into a hood-like form. Unlike the viper, it is also speed-offering, attacking when threatened, and likely to pursue or trap an apparent threat. Habitat and distribution They are both indigenous to Sub-Saharan Africa, but they occupy different habitats. Gaboon viper usually inhabits rainforests and dense woods, whereas black mamba inhabits savannahs, rocky hills, and open woods, allowing it a wider spread geographical habitat and more encounters with humans. Lifespan In the wild, Gaboon vipers live for about 10 years, but can live as long as 20 years in captivity under favorable care. Black mambas live a bit longer in the wild, with an average of 11 years, and can reach 20 years or more in captivity. Black mamba vs Gaboon Viper: Which snake is more deadly to humans Both snakes are deadly to a human, but the black mamba is unequivocally more dangerous to humans. Although the Gaboon viper yields more venom, it is less aggressive, more shy, and less likely to bite until provoked. The black mamba, on the other hand, is extremely territorial, swift, and able to inflict several lethal bites with neurotoxic venom that takes effect in a hurry. It kills within 30 minutes to one hour, and bites that remain untreated carry a 90–100% chance of death. Because of its potency, aggression, and willingness to attack, the black mamba is considered the most venomous snake in Africa—and perhaps the planet.

Meet Gaboon viper, the snake with the longest fangs
It doesn't hiss. It doesn't chase. It doesn't warn. But when the Gaboon viper strikes — it does so with unmatched precision and the longest fangs in the snake world. Native to the rainforests and savannahs of sub-Saharan Africa, the Gaboon viper (Bitis gabonica) is often misunderstood and rarely seen — unless you happen to step too close. If snakes had an invisibility cloak, this one would wear it best.
