Tropidonophis mairii, commonly known as the common keelback, Mair's keelback,^[1] the keelback, or the freshwater snake, is a species of nonvenomous snake found throughout Northern Australia.

Etymology

The specific name, mairii, is in honor of "Dr. Mair", an army surgeon with the 39th Regiment of Foot, who collected the holotype.^[2]

Description

T. mairii resembles two venomous snakes, the taipan and the rough-scaled snake. T. mairii rarely grows over 1 m (39 in) in total length (including tail).

Diet

Mair's keelback feeds mainly on amphibians and small lizards. It is one of the few snakes that can eat cane toads (Rhinella marina), up to a certain size, without being harmed.
