A [[Burmese python]] skull (''[[Python bivittatus]]'')]]'''Aglyphous''' snakes (''lacking grooves'') have no specialized teeth; each tooth is similar in shape and often size.  When teeth vary in size, as in some bird eaters, they do not vary in shape.  Most aglyphous snakes are non-venomous; some, like ''[[Garter snake|Thamnophis]]'', are considered mildly venomous. The feature is not a [[synapomorphy]].{{clear}}
