Colubroidea

Colubroidea is a superfamily of snakes in the clade Colubroides that include Colubridae and a few other related families. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families.[1][2][3][4] Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids.[1]
