AROD > Reptiles / Squamata / Colubridae
|Etymology:||From coluber, Latin for 'snake'.|
This is the dominant family of snakes in all parts of the world except Australia. Two subfamilies are found in Australia:
Natricinae - after the Latin natricis, a water snake.
Represented only by the non-venomous keelback (Tropidonophis mairii). Natricine snakes are toad eaters, and the keelback is the only Australian snake that can regularly eat the introduced and highly toxic cane toad.
Colubrinae - from coluber, Latin for 'snake'.
The largest and most diverse group worldwide. Non- or weakly-venomous.
The former subfamily Homalopsinae (from homalos and opsis, Greek for 'even' and 'appearance') has been elevated to its own family, Homalopsidae. It contains aquatic and semi-aquatic snakes that are weakly venomous.
