The mountain garter snake ( Thamnophis elegans ) is a species of snake of the genus Garter Snake ( Thamnophis ).
features
Females are usually up to 110 cm long, males rarely longer than 60 cm.
They have a wide range of food for garter snakes and eat amphibians , worms , fish , small mammals and other reptiles .
These snakes are viviparous . A litter usually contains five to 20 young animals.
Questionable subspecies
Currently the species is divided into six subspecies. As with other species of garter snakes, the assignment of the subspecies is also controversial with Thamnophis elegans . The Upper Basin garter snake ( T. elegans vascotanneri ) may be equated with the migratory garter snake ( T. elegans vagrans ). The subspecies status of the coastal garter snake ( T. elegans terrestris ) and the Arizona garter snake ( T. elegans arizonae ) has also been questioned.

The habitat of the mountain garter snakes stretches from British Columbia and Alberta in western Canada through the states of Washington and Montana in the northwest of the USA to the south of California and Arizona . They can also be found in the state of Baja California in Mexico .
