I have a pet snake! Do you like snakes?

Many snakes have skulls with way more joints than their lizard ancestors.

Neat! I think I've heard about that before. I really like the snakes from tropical areas.

And some species have retained  a pelvic girdle with a pair of vestigial claws on either side of the cloaca

Wow! That sounds unique! I bet some snake species have even gone extinct with similar characteristics.

Snakes resemble legless lizards. The difference is the lizards have eyelids and external ears.

Yep! I think lizards are cuter than snakes because they limbs haha. Though I adore my pet cobra!

Snakes can be found on every continent except Antarctica.
