Toxicofera

Toxicofera (Latin for "toxin-bearers") is a clade of scaled reptiles (squamates) that includes the Serpentes (snakes), Anguimorpha (monitor lizards, beaded lizards, and alligator lizards) and Iguania (iguanas, agamas, and chameleons). Toxicofera contains about 4,600 species (nearly 60%) of extant Squamata. It encompasses all venomous reptile species, as well as numerous related non-venomous species. There is little morphological evidence to support this grouping; however, it has been recovered by all molecular analyses as of 2012.
