Family-Animalia: Varanidae

The Varanidae are a family of lizards in the superfamily Varanoidea. The family, a group of carnivorous and frugivorous lizards, includes the living genus Varanus, the extinct Megalania (the largest known land-dwelling lizard), and a number of other extinct taxa. Varanus includes the Komodo dragon (the largest living lizard), crocodile monitor, savannah monitor, the goannas of Australia and Southeast Asia, and various other species with a similarly distinctive appearance. Their closest living relatives are the anguid and helodermatid lizards.
