Main predators of adults are snakes, alligators, birds, turtles, carnivorous/omnivorous mammals, & bullfrogs. Larvae eaten by larger salamander larvae (including own species), adult salamanders (including own species), aquatic insects, newts, fish, frogs, & toads.

Adults migrate to breeding areas in late winter/early spring, w/ males attaching spermatophores to underwater rocks/logs. Females fertilize eggs w/ spermatophores. Eggs laid 1-2 days after courtship. Females can lay 100-1000 eggs per season, with eggs hatching a month later. Larvae remain in birth pool until subadult stage at 2.5-5 months old, not sexually mature until age 4. Some adults (neotenes) retain larval form whole life. Larvae that don’t metamorphose until fully adult called waterdogs. 2 morphs of larvae-normal & cannibal. Cannibal morph even more cannibalistic than normal & grow/metamorphose faster. Adults of this morph keep larger head/bigger mouth of larvae.

Fun Fact(s):

They can make good pets.
