Description
T. hammondii is a medium-sized snake, 18–30 in (46–76 cm) in total length (including tail), with a head barely wider than the neck. Two common color variations occur in the wild, a striped variant and a checkered variant. The striped variant has a yellowish lateral stripe on each side, and a fairly uniform dorsal coloring. The checkered variant lacks the lateral stripes and has two rows of small dark spots on each side.
Range & habitat
The two-striped garter snake is found in western North America, ranging from central California to Baja California, Mexico. It is a highly aquatic species, and prefers habitat adjacent to permanent or semi-permanent bodies of water. This species feeds primarily on fishes and amphibians.
