Common names: advanced snakes.

The Alethinophidia are an infraorder of snakes that includes all snakes other than blind snakes and thread snakes. wikt:ἀλήθεια means 'true'. In the past, snakes were grouped into families within Alethinophidia based on their morphology, especially that of their teeth. More modern phylogenetic hypotheses using genetic data[1][2][3][4][5][6][7][8][9][10] support the recognition of 19 extant families (see below), although the taxonomy of alethinophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank (such as a superfamily, family, or subfamily) is arbitrary.
