Ambystoma amblycephalum (Blunt-headed salamander)

Language: Spanish

Wikipedia Abstract

The blunt-headed Salamander (Ambystoma amblycephalum) is a mole salamander endemic to Mexico. It is only known from the vicinity of its type locality, near Morelia, in Michoacán state in Southwestern Mexico. It inhabits a landscape consisting of a mosaic of natural grasslands and pine-oak forests at elevations of about 2,000 m (6,600 ft) asl). Breeding takes place in ponds.

EDGE Analysis

The blunt-headed salamander is a metamorphosing species of mole salamander, which means that it can make the full transition from aquatic larval form to a terrestrial adult form in its lifetime. The adult spends the majority of its time on land in a mosaic of natural grasslands and pine-oak forests. It is highly evolutionarily distinct, the family diverging from all other salamanders in the Early Cretaceous period over 140 million years ago, around five million years before the koala and dolphin lineages diverged from their common ancestor. Today, the desiccation, pollution and conversion of former ponds, small reservoirs, and open habitat to row crops, represents the main threat to the species’ survival.
