Garter Snake

🌍 Overview

The common garter snake is one of the most widely distributed reptiles in North America, found in gardens, wetlands, and vacant lots from Florida to coastal Quebec and west to British Columbia - genuinely one of the most common "found in the backyard" snakes in the US. Unlike most snakes kept as pets, garter snakes are live-bearing (ovoviviparous) rather than egg-laying, and they're semi-aquatic hunters that key in on fish, earthworms, slugs, and amphibians rather than rodents - many individuals never accept a plain mouse. Like the hognose snake, they carry a mild rear-fanged venom from a Duvernoy's gland that helps subdue small prey but is harmless to people in normal handling. Cheap, hardy, and small, they're an accessible pet as long as a keeper is prepared to source fish and worms instead of relying on frozen mice.

📋 Quick Facts

📜 History

Garter snakes have a scientific history most pet species never acquire. The genus Thamnophis is one of the major vertebrate models in organismal biology, used for work on speciation, toxin resistance, pheromonal communication, behavior genetics, and reproductive physiology, and the common garter snake's genome has been sequenced. Its resistance to the tetrodotoxin carried by newts it eats is one of the most studied predator and prey arms races in vertebrates. A snake a child can find in a vacant lot is also one of the best understood reptiles in the laboratory.
