Habitat and Ecology
This species is native to the ancient system of water channels and lakes in Mexico City. It requires deep-water lakes (both natural and artificial canals) with abundant aquatic vegetation. Structures such as plants are needed to lay eggs. It is a paedomorphic species, living permanently in water, and does not undergo complete metamorphosis.
Systems: Freshwater
ีuse and Trade: Wild harvest is small but not necessarily in relation to population size. There is a local illegal trade in wild-caught animals for human consumption, medicinal uses and pets. It is assumed that all international trade is now in captive-bred animals.
