These include the slowworm and glass snake. The majority of snakes do not seek [17]:81, The majority of snakes eat a variety of prey animals, but there is some specialization in certain species. It's also been observed in snakes that molting can be synced to mating cycles. The theory postulates that snakes may have evolved from a common lizard ancestor that was venomous, and also that venomous lizards like the gila monster, beaded lizard, monitor lizards, and the now-extinct mosasaurs, may have derived from this same common ancestor. The venom is modified saliva, delivered through fangs.

[76] A female python will not leave the eggs, except to occasionally bask in the sun or drink water. For instance, many sources classify Boidae and Pythonidae as one family, while some keep the Elapidae and Hydrophiidae (sea snakes) separate for practical reasons despite their extremely close relation. Note: the tree only indicates relationships, not evolutionary branching times. Senior cats are 11 to 14 years oldsomething like 60s and 70s for people. [100] This high cost is due to the repeated stops and starts of portions of the body as well as the necessity of using active muscular effort to brace against the tunnel walls. The process of moving from one open window to another is called what? Species of the family Pareidae have more teeth on the right side of their mouths than on the left, as they mostly prey on snails and the shells usually spiral clockwise. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards.
