Description

Anderson's Salamander, "Ambystoma andersoni", is a neotenic salamander from Laguna de Zacapú in the Mexican state of Michoacán.

This salamander is a relatively recent discovery, first described by Brandon and Krebs in 1984. "Ambystoma andersoni" is named for James Anderson, a herpetologist with the American Museum of Natural History who did extensive fieldwork studying Ambystoma and other herp species in Mexico.

Like all neotenic "Ambystoma" species, "andersoni" retains its larval features into adulthood. The mature salamander has medium-sized external gills with bright red filaments, and a prominent caudal fin. It has a large head and small limbs, as do the larvae. Its coloration is a strange pattern of black blotches on a red-brown base. The salamanders are totally aquatic and spend their whole lives in the same body of water.

Habitat

Lake Zacapu is small lake near Zacapu, sitting at an altitude of 2000 meters. The lake is located within the Mesa Central portion of Mexico, an area home to many neotenic Ambystoma species. It is temperate, with low salinity, and has a single stream originating from it.

The status of this species is unknown.
