Snake Outer Beauty. Most reptiles have four legs. Snakes, however, do not have legs. They also lack a pectoral girdle (shoulder bones) and — with the exception of the boids, which retain a vestigial pelvis and external spurs — they also lack a pelvic girdle (rear leg support).

Do pythons have claws?

Like all pythons and boas, ball pythons have anal spurs. These single claws appear on both sides of the vent. They are the vestigial remnants of the hind legs that snakes lost during the evolution of lizards to snake. Males have longer spurs and smaller heads than females.

Do only male snakes have spurs?

Both male and female ball pythons have spurs, but spurs in males are often larger and slightly more hooked inwards. Spurs are small leg-like structures from both sides of the cloaca. These spurs are used when mating, climbing and fighting.
