Yellow-throated Garter Snake
Thamnophis pulchrilatus
The yellow-throated garter snake (Thamnophis pulchrilatus) is a species of snake in the family Colubridae. It is found in Mexico. Very little is known for certain about this snake, but it has been observed to reach lengths of 18–36 in (46–91 cm). They are distinguishable by their characteristic coloring, having a dark brown or black dorsal side accented with a yellow to light green stripe along the spine. A checkered yellow and black pattern can be observed along the sides, and the throat of the snake is bright yellow. Thamnophis pulchrilatus are relatively slender and light snakes.

Range & habitat
It is found mainly in wooded areas, specifically oak and pine forests at high elevations, but has occasionally been found in grassy fields as well. Some sources report that they inhabit the southwestern United States, but no sightings have ever been confirmed outside of Mexico, and these U.S. reports are likely T. cyrtopsis or T. eques.

What it does
These snakes are believed to eat small fish, lizards, frogs, toads, and even worms. There have been two confirmed cases of predation: the first involved a captured female that regurgitated a mountain tree frog (Dryophytes eximius), and the second was a captured snake that was discovered to have eaten a Bell's false brook salamander (Isthmura belli).
