Preserving sperm vital to saving 'snot otter' salamanders
Date:8/4/2010

EAST LANSING, Mich. The hellbender salamander known affectionately as a snot otter or devil dog is one of America's unique giant salamander species. For unexplained reasons, most hellbender populations have rapidly declined as very little reproduction has occurred in recent decades.

Working with researchers from the Nashville Zoo and Antwerp Zoo in Belgium, veterinarians from Michigan State University are helping develop conservation techniques to sample and freeze the sperm from some of the last surviving salamanders. The international consortium's work aims to enable future re-stocking of genetically viable hellbenders back to their streams and rivers, ensuring the survival of the species.

The largest salamander found in North America, the hellbender can grow to up to 30 inches long and live 30 years or more. They live in a geographic range from Arkansas northeast to New York and have remained relatively unchanged since the time of the dinosaurs.

Dalen Agnew and Carla Carleton from MSU's College of Veterinary Medicine are focusing specifically on evaluating the freezing techniques, known as cryopreservation, developed to keep the hellbender sperm viable.

"The hellbender in the United States is becoming endangered, and to make things more difficult, they are very secretive," said Agnew, a member of the college's Department of Pathobiology and Diagnostic Investigation. "The best we can tell, in most hellbender populations there has been no breeding in the wild for several decades."

While other researchers figure out why environmental degradation, habitat loss and biological changes are all possibilities the team led by Robert Browne of the Antwerp Zoo along with Sally Nofs and Dale McGinnity of the Nashville Zoo is making sure the species does not go extinct, preserving its genetic diversity.
