Rubber Boa (Charinna bottae)

Rubber Boas are the northernmost members of the Boa family, and are native to North America.

These small snakes may initially look like giant millipedes or earthworms.

Rubber Boas are docile, feeling almost rubbery.

Rubber Boa bellies are often pale yellow. And one defense mechanism is to bury their heads while waving their blunt, head-like tails.

The top of the head is covered with large, symmetrical plates.

Anal spurs are the evolutionary remnants of hind limbs.

Although non-venomous and harmless to people, Boas have vertical pupils.
