Colubrid snakes (Colubridae)

Colubrid snakes (Colubridae) is a family in Squamata that includes 304 genera and 2000 species as the largest snake family and includes 2/3 of all snake species, has a variety of colors, shapes and sizes, most of them do not have venom, some have low to medium venom and some are highly venomous.

Colubridae includes many snakes that do not fit any other criteria so this family is a taxon shelter which causes it to be very diverse and numerous. Colubrid snakes are the earliest species as the ancestors of most snake species that exist today.

Most of the colubrid species are non-venomous snakes, although the family classification also includes venomous snakes. The venomous snakes that belong to the Colubridae are venomous snakes with back teeth where the venom is located in the back of the upper jaw, not in front as in Elapidae or Viperidae.

Most of the colubrid which is venomous is not dangerous to humans, but some species such as Boiga dendrophila can have serious consequences, even the bites of Dispholidus typus and Thelotornis are capable of killing humans.
