West-African gaboon viper (Bitis rhinoceros). This snake has the longest fangs of any snake on earth, reaching 2.5 inches long.

It prefers wet or damp environments and can even be found on plantations. The body is massive with rough and strongly keeled scales. It possesses a green or blue triangular head with a large black arrowhead mark on the top and two or three pairs of hornlike scales on the tip of the snout.

Although it produces a significant amount of venom, the disposition of this large snake is rather mild, and it rarely bites or causes death in humans. It can produce a prolonged warning exhalation or hiss when disturbed.
