Ambystoma amblycephalum (Blunt-headed salamander)

Language: Spanish

Wikipedia Abstract

The Blunt-headed Salamander (Ambystoma amblycephalum) is a mole salamander from high elevations (9000 ft above sea level) 15 miles west of Morelia, Michoacán, Mexico. It has both neotenic and terrestrial populations. Neotenic populations are perennibranchiate and retain their fins. Neotenes are very long with extremely short, blunt heads and round eyes. They have relatively short, thick gills. Their coloring is dark brown-gray dorsally, with a lighter gray under-belly.

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.
