  • Ordinary mountain garter snake T. elegans elegans ( BAIRD & GIRARD, 1853)
  • San Pedro Martir garter snake T. elegans hamnophis hueyi ( VAN DENBURGH & SLEVIN, 1923)
  • Coast Garter Snake T. elegans terrestris (FOX, 1951)
  • Wandering Garter Snake T. elegans vagrans ( BAIRD & GIRARD, 1853)

The mountain garter snake ( Thamnophis elegans ) is a species of snake of the genus garter snakes ( 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 includes five to 20 pups.

Questionable subspecies

Currently, the species is divided into six subspecies. As with other types of garter snakes but the assignment of the subspecies is controversial even in Thamnophis elegans. Thus, the Upper Basin Garter Snake ( T. elegans vascotanneri ) possibly the Wandering Garter Snake ( T. elegans vagrans ) equal footing. Even the subspecies status of the coastal Garter Snake ( T. elegans terrestris) and the Arizona Garter Snake ( T. elegans arizonae ) is doubted.

Dissemination

The habitat of the mountain garter snakes extends from British Columbia and Alberta in western Canada across the states of Washington and Montana in the north- western United States to southern California and Arizona. Also in the state of Baja California in Mexico they are found.
