Gaboon Viper

Bitis gabonica

Also known as Gaboon Adder, Butterfly Adder, Forest Puff Adder

Blending seamlessly into tropical forest leaf litter, Gaboon vipers feature intricate geometric patterns of buff, brown, and purple that render them almost invisible. They remain motionless for days while awaiting passing prey, then deliver a strike of astonishing speed and precision. Equipped with fangs reaching up to five centimeters long and massive venom glands, these heavy-bodied snakes hold prey firmly until their potent venom takes full effect.

How to recognize a risky encounter
Distinguished by a broad triangular head, small nose horns, and a striking geometric pattern of tan, purple, and brown that blends into leaf litter.
What to do
Never approach or attempt to move this snake, and step back slowly if spotted on the forest floor.
What to notice

Responsible observation
  • Watch Your Step: Scan forest leaf litter carefully before stepping off established trails in rainforest environments.
  • Keep Distance: Stay several meters away if spotted, as their strike range is surprisingly long despite a sluggish appearance.
