Tamaulipan Milksnake

Lampropeltis annulata

Also known as Mexican Milksnake

Tamaulipan milksnakes are secretive nocturnal constrictors famous for their brilliant tricolor banding that mimics venomous coral snakes. During scorching desert days, they hide beneath flat rocks, fallen logs, or inside abandoned rodent burrows before emerging after dark to hunt. When threatened, they often tuck their heads beneath coiled loops of their body and vibrate their tail tips against leaf litter to deter potential predators.
