Species Profiles
Axolotl
Ambystoma mexicanum
Axolotls are fully aquatic salamanders native to Mexico City's Lake Xochimilco. Critically endangered in the wild, they thrive in captivity and have become incredibly popular pets. Known for their permanent larval form, external gills, and remarkable regeneration ability, axolotls require cool water and specific care that differs from typical fish keeping.
