Proteus anguinus (Olm)

Wikipedia Abstract

The olm, or proteus (Proteus anguinus), is a blind amphibian endemic to the subterranean waters of caves of the Dinaric karst of Central and Southeastern Europe. It lives in the waters that flow underground through this extensive limestone region, including waters of the Soča river basin near Trieste, Italy, through to southern Slovenia, southwestern Croatia, and Herzegovina.

EDGE Analysis

The olm is a Europe’s only cave adapted vertebrate, and has numerous adaptations for an underground life. Olms hunt their prey in the absolute dark and have developed a powerful sensory system of smell, taste, hearing and electrosensitivity. Olms are pale and sightless, although their skin-covered eyes are still light sensitive. They are an entirely aquatic species that can survive without food for up to 10 years and live to an age of 58 or more. Part of an ancient lineage of amphibians evolving independently for 190 million years, this species is now threatened by pollution and habitat disturbance. A small subpopulation of “black olms” may be a separate species requiring additional protection.
