84 known species[2] Oligodon is genus of colubrid snakes that was first described by Austrian zoologist Leopold Fitzinger in 1826.

[3] The species in the genus Oligodon are egg eaters and are usually under 90 cm (35 in) in total length (including tail).

Besides eggs, species of this genus also feeds on lizards, frogs, and small rodents.

All member species have a set of enlarged teeth placed in the back of the upper jaws, as well as functional Duvernoy's glands.

Bites by some species have been reported to bleed excessively, suggesting presence of anticoagulants in the Duvernoy's gland secretions.
