Lizards, snakes and the burrowing amphisbaenids make up the
order Squamata, meaning the scaly ones. The elongate, slim,
long-tailed bodies of lizards have become modified to enable
them to live in a wide range of habitats. Lizards can be
expert burrowers, runners, swimmers and climbers, and a few
can manage crude, short-distance gliding on rib-supported
"wings". Most are carnivores, feeding on invertebrate and
small vertebrate prey, but others feed on vegetation.
