Mexican Alpine Blotched Garter

Thamnophis scaliger

The Mexican alpine blotched garter snake, Thamnophis scaliger, is a small highland garter snake associated with cool, moist habitats in Mexico. Its common name points to both its mountain setting and the broken blotched pattern that can interrupt the cleaner stripes seen in many garter snakes. Like other Thamnophis, it is live-bearing, active by day when conditions allow, and tied closely to wet meadows, marsh edges, springs, or slow stream margins.

Captive or institutional work with this snake is a specialist matter, partly because high-elevation garter snakes may not thrive under generic warm reptile-room conditions. Stable cooler gradients, clean water, secure hides, and appropriate fish, amphibian, or invertebrate prey matter more than display value. Locality records are useful for this group because Mexican garter snakes can be taxonomically confusing, and conservation concerns often depend on the exact population and watershed.
