Hellbenders Rock
20 November 2013
We love hellbenders. But they’re not the cuddliest of species, with their slimy bodies that look like the 2-foot-long lovechild of phlegm and a rock. Actually these critters — also called (by people not on the Center’s staff) “devil dogs” and “snot otters” — are pretty much a PR nightmare for anyone trying to fight off their extinction due to water pollution and dams. The rallying cry “Save the Snot Otter” doesn’t always go over well.
Happily for the hellbender, a band from St. Louis is now doing this salamander justice through song. They may yet make a rock ‘n’ roll legend out of North America’s largest amphibian.
We think there are few things more rockin’ than raising a little hellbender.
NATURAL HISTORY
HELLBENDER: Cryptobranchus alleganiensis
FAMILY: CryptobranchidaeDESCRIPTION: Hellbenders are considered to be living fossils because they have changed so little over time. They are large, stout-bodied, fully-aquatic salamanders that grow to be two feet long with brown, grey or black skin with lighter markings. Hellbenders have flattened bodies and heads that allow them to cling to the river bottom, as well as a rough pad on their toes for traction on slick rocks. They have paddle-like tails for swimming, and numerous folds of fleshy skin for oxygen absorption. Their eyes are small, without lids, and their skin secretes toxic slime to ward off predators.
HABITAT: This salamander occurs in rocky, clear creeks and rivers, usually where there are large shelter rocks. It generally avoids water warmer than 68 degrees Fahrenheit. Males prepare nests and attend eggs beneath large, flat rocks or submerged logs.
RANGE: This species is found in Alabama, Arkansas, Georgia, Indiana, Kentucky, Maryland, Missouri, Mississippi, North Carolina, New York, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia and West Virginia. The Ozark subspecies is found only in southern Missouri and northern Arkansas.
MIGRATION: The hellbender does not migrate.
BREEDING: Hellbender breeding is aquatic. Males may move short distances within their home ranges to brooding sites. The breeding season is variable but occurs mainly in September and October; a male prepares a nest by moving gravel to create a saucer-shaped depression, then depositing 200-400 eggs in the depression. The male fertilizes the eggs and guards the nests until the young are about three weeks old.
LIFE CYCLE: Newly hatched larvae are approximately 1.2 inches long. Development is rapid, and hatchlings double their size in the first year. Larvae normally lose their external gills in the second summer after hatching. Hellbenders reach sexual maturity at five to six years and may live as long as 30 years.
FEEDING: Crayfish are the most important food items for hellbenders, but the salamanders’ diet also includes fish, insects, earthworms, snails, tadpoles, fish eggs, other hellbenders and other hellbenders’ eggs.
THREATS: This species is mainly threatened by poor water quality, unsustainable collection for the pet trade and scientific purposes, persecution by anglers, disease caused by chytrid fungus, stocking of predatory fish and loss of genetic diversity.
POPULATION TREND: The hellbender is declining throughout its range. The Ozark hellbender in southern Missouri and northern Arkansas is in especially alarming decline.
Action timeline
May 4, 2004 — The Center petitioned the U.S. Fish and Wildlife Service to list 225 candidate species, including the Ozark hellbender.
April 20, 2010 — The Center petitioned to list 404 aquatic, riparian and wetland species in the southeastern United States as threatened or endangered, including the hellbender.
September 8, 2010 — The Service issued a proposed rule to list the Ozark hellbender as endangered but refused to designate critical habitat.
November 8, 2010 — The Center filed comments with the Fish and Wildlife Service urging the Service to designate critical habitat for the Ozark hellbender.
July 12, 2011 — The Center reached a landmark agreement with the Fish and Wildlife Service compelling the agency to move forward in the protection process for 757 species, including the Ozark and eastern hellbenders.
October 5, 2011 — The Service issued a final rule listing the Ozark hellbender as an endangered species under the Endangered Species Act as part of our 757 species agreement.
January 31, 2013 — The Center and the Missouri Coalition for the Environment filed a formal notice of intent to sue the U.S. Forest Service and U.S. Fish and Wildlife Service over the agencies’ failure to protect the Ozark hellbender, Hine’s emerald dragonfly, Tumbling Creek cavesnail and two endangered mussels on Missouri’s Mark Twain National Forest, where logging, road use and other activities are polluting waterways.

I live in the upper Susquehanna valley, NY, and there is nothing like fishing at night and finding that you have a hellbender (our “mudpuppy”) all wound up in your fishing line because it has been spinning round and round like an alligator. Then you cut the line because it is pure slime and then unwind the mudpuppy and send it back towards its home.

Hi, this site

Eastern hellbenders occupy the Susquehanna River drainage in southern New York and Pennsylvania, and large portions Missouri, Ohio, and Mississippi River drainages from western Pennsylvania, southern Ohio, extreme southern Indiana, most of West Virginia, Kentucky, and Tennessee, northern Alabama and Georgia, western North Carolina and Virginia.
Mudpuppies are a different species than hellbenders:

They only grow to 30, exceptionally to 40 centimeter. While hellbenders can grow to over 60 centimeter.

You may be correct and you may be incorrect. The description of the mudpuppy lines up correctly to my casual encounter with them. However, I have seen some close to 24 inches long.
The answer may be that I have seen both species and was so casual an observer that I did not discriminate between the two. However, I have seen both up close and UGLY. And I have seen them in both murky dirty water and after NY started cleaning up the Susquehanna River.
Let me add a personal view here: The Susquehanna had a much broader range of fish and frogs and salamanders and mudpuppies and turtles BEFORE they cleaned up the river.
I fished the river as a kid in 1948 and through the years until 2010. I know what I have seen and I know what has disappeared.
The river does not have RAW sewage in it (for the most part) any longer but there continues to be pristine fecal matter still floating down the river.
Its pristine condition has been imparted by the sewage treatment plants but it remains fecal matter.
Just an observation.

Apart from their smaller size: adult mudpuppies have gills, which hellbenders have not.

Maybe mudpuppies are more tolerant of polluted water than hellbenders?

Thanks for the links. They were indeed hellbenders even though we called them mudpuppies.
There was a fish that was also called a mudpuppy. It had no legs and lived in clean lakes. It could live on land (which is where the adults told us to throw them) for a very long time. Possibly it was a salamander mudpuppy and as a child I never noticed the legs (or possibly immature ones had tiny legs that I took for fins). Thanks again.

Hellbenders belong to a very ancient salamander lineage. Their closest relatives are Japanese and Chinese giant salamanders. While mudpuppies are more closely related to “mainstream” salamanders.

The Salamander has something to do with surviving fire, I thought, a symbol used in hot glass blowing, or a mythology?
