Most common garter snakes have a pattern of yellow stripes on a black, brown or green background, and their average total length (including tail) is about 55 cm (22 in), with a maximum total length of about 137 cm (54 in). [2] [3] The average body mass is 150 g (5.3 oz). [4] The common garter snake is the state reptile of Massachusetts. [5]
Garter snake is the common name for small to medium-sized snakes ... implying co-evolution between predator and prey. [16] Garter snakes feeding on toxic newts can ...
In each of these populations, the snakes exhibit resistance to the toxin and successfully prey upon the newts. Successful predation of the rough-skinned newt by the common garter snake is made possible by the ability of individuals in a common garter snake population to gauge whether the newt's level of toxin is too high to feed on.
Small garter snakes eat prey such as slugs and earthworms, but larger garter snakes eat birds, fish, amphibians and rodents. The common garter snake species is often found in mountainous areas ...
The scientific name Thamnophis sirtalis sirtalis is a combination of Ancient Greek and New Latin that means "bush snake that looks like a garter strap". The generic name Thamnophis is derived from the Greek "thamnos" (bush) and "ophis" (snake) and the specific name sirtalis is derived from the New Latin "siratalis" (like a garter), a reference to the snake's color pattern resembling a striped ...
Rough-skinned newts have skin glands that contain a powerful nerve poison, tetrodotoxin, as an anti-predator adaptation. Throughout much of the newt's range, the common garter snake is resistant to the toxin. While in principle the toxin binds to a tube-shaped protein that acts as a sodium channel in the snake's nerve cells, a mutation in ...

The main native predator of the California Coast Range newt is the common garter snake (Thamnophis sirtalis), some of which have apparently developed a genetic resistance or immunity to tetrodotoxin. Reproduction
