Where the name comes from

Gabonica names Gabon, though the species occupies a belt of forest from Guinea to Uganda. The name says nothing about its appearance, which is the real distinction: the pattern of the back is a run of rectangles, triangles and hourglasses in the colours of dead leaves, and it is probably the most effective camouflage of any snake in the world.

What sets it apart

It does not let go. Nearly all venomous snakes strike and withdraw at once, to avoid injury from thrashing prey; this one strikes and holds on, waiting for the animal to die between its jaws. It can afford to because it is huge, muscular and imperturbable, and because on the forest floor it has nothing to fear. Herpetologists describe it as one of the most placid snakes alive: almost every documented bite involves somebody who had picked it up off the ground, mistaking it for a pile of leaves.
