Adults are known to eat earthworms. Reproduction Ambystoma californiense breeds from late winter into early spring in large temporary ponds. They are explosive breeders, meaning they emerge, breed quickly, and then return to their burrows. They may breed two or three times a year this way. Juveniles migrate from these ponds to underground burrows in the spring during the rains.
Females attach one egg at a time to twigs, grass stems, vegetation, or detrious.
These eggs are covered by a vitelline membrane and three jelly coats. Larvae coloring is yellowish gray. Behavior Ambystoma californiense burrows into Spermophilus spp. Adults are able to move at a rate of 50.8 meters per hour, while juveniles can only move at a rate of about 30.9 meters per hour. Habitat Ambystoma californiense likes a Mediterranean climate of cool wet winters and hot dry summers.
