Some species retain a pelvic girdle by using a set of vestigial claws on both aspect with the cloaca. Lizards have independently advanced elongate bodies with no limbs or with considerably minimized limbs a minimum of 20-5 occasions through convergent evolution, leading to lots of lineages of legless lizards.[3] These resemble snakes, but several typical groups of legless lizards have eyelids and external ears, which snakes lack, While this rule is not really common (see Amphisbaenia, Dibamidae, and Pygopodidae).

 Vipera berus, a person fang in glove with a small venom stain, one other even now set up Snakes do not ordinarily prey on human beings.
