| With their growth in popularity as domestics pets, lizards are being presented to veterinary surgeons in increasing numbers. They are a diverse group of animals and can often pose problems for vets who have seldom, or perhaps never, handled them. | | With their growth in popularity as domestics pets, lizards are being presented to veterinary surgeons in increasing numbers.

| * Lizards are a very large and widespread group of the reptilian order Squamata. The nearly 7200 species of lizards are the most diverse and speciose living clade of reptiles; of course this total includes the worm lizards and snakes (which are actually reduced-limbed or limbless lizards). However, because snakes are a monophyletic group arising from within a group of lizards, the taxon Serpentes and its definition delimit a monophyletic group. Herein, the term lizard represents our shared perception and excludes Serpentes and Amphisbaenia. | | * Lizards are a very large and widespread group of the reptilian order Squamata.
