A master of disguise with the longest fangs
The Gaboon viper (Bitis gabonica) is a heavy-bodied, powerfully camouflaged snake found in the forests and woodlands of sub-Saharan Africa. With a dramatic pattern of browns, tans, and purples it melts into leaf litter, waiting patiently for prey to wander by.
Despite its bulk, the Gaboon viper is an expert ambush hunter. It strikes with astonishing speed and delivers one of the largest venom loads of any snake, aided by fangs that can reach several centimeters in length. Still, these vipers are slow-moving and prefer to remain unseen rather than seek out confrontation.

Habitat
Gaboon vipers favor dense, humid environments with abundant leaf cover. They are most common in lowland rainforests, riverine forests, and shaded areas where the leaf litter provides perfect concealment. Their heavy bodies and short tails make them well-suited to slow, patient life on the forest floor.
These snakes use the forest floor as both hunting ground and shelter. When disturbed, they usually remain motionless and rely on camouflage. They are most active at night and during the cooler hours of dawn and dusk in hotter regions.
Behavior
Gaboon vipers are ambush predators. They lie in wait, often in a coil, and strike with explosive speed when a rodent or bird comes near. Their strike is short and precise and their long fangs allow deep venom delivery into prey.
They are generally docile and sluggish when not provoked, which can give the mistaken impression that they are slow to react. In reality, they are perfectly adapted to sit and wait for extended periods. Females give birth to live young in a single brood each year, and the young are independent from birth.
Because they rely on camouflage, they are rarely seen. When encounters with people do occur, the risk is usually from accidental close contact on the forest floor. Respect for their habitat and common sense in the field greatly reduces the chance of bites.
FAQs
Are Gaboon vipers deadly to humans?
Their venom is powerful, and envenomation can be serious or fatal without prompt medical care. That said, Gaboon vipers are not aggressive and bites are relatively rare when people give them space.
How long are their fangs?
Gaboon viper fangs are among the longest of any snake, often reaching several centimeters. Those long fangs let the snake deliver venom deep into its prey in a single strike.
Do they hunt during the day or night?
They are primarily crepuscular and nocturnal, meaning they are most active at dawn, dusk, and during the night in many areas.
Can they climb trees or swim?
They are mainly ground-dwelling and not known as strong climbers. They can swim if needed, but prefer the cover of dense leaf litter.
How can I avoid a bite in the wild?
Watch where you step, avoid putting hands into thick leaf litter or under logs, wear sturdy boots in known habitat, and give any snake plenty of space to retreat.
