Some of the things that tiger salamanders eat in their natural habitats are slugs, snails, worms and insects. Tiger salamanders living in captivity may be fed baby snakes, other small salamanders, newborn mice and frogs. The larvae of tiger salamanders eat insect larvae and crustaceans and will not consume larger prey until they fully mature.
Tiger salamanders mainly dig their own burrows and spend most of their lives underground where they are safe from predators and temperatures that may be too cold for them. Predators such as owls, badgers and snakes eat tiger salamanders, while the younger larvae are preyed on by snakes and aquatic insects.
