Legless lizards resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamidae, and Pygopodidae).
Living snakes are found on every continent except Antarctica, and on most smaller
. Python embryos even have fully developed hind limb buds, but their later development is stopped by the DNA mutations in the ZRS.
Distribution.

Snakes can be found on every continent except Antarctica, in the sea, and as high as in the Himalayan Mountains of Asia.
