In New York, the hellbender is found solely in the Susquehanna and Allegheny River drainages, including their associated tributaries. He then waits to entice a female to his space. [22] The same collector noted, he "never found two specimens under the same rock", corroborating the account given by other researchers that hellbenders are generally solitary; they are thought to gather only during the mating season. Distribution and Habitat The eastern hellbender's North American range extends from southwestern and southcentral New York, west to southern Illinois, and south to extreme northeastern Mississippi and the northern parts of Alabama and Georgia. Anywhere, any time. Cannibalism, however, leads to a much lower number of eggs in hellbender nests than would be predicted by egg counts. C. alleganiensis has a flat body and head, with beady dorsal eyes and slimy skin. [27], The Ozark hellbender was successfully bred in captivity for the first time at the St. Louis Zoo, in a joint project with the Missouri Department of Conservation, hatching on November 15, 2011. With Clifton Collins Jr., Clancy Brown, Andre Royo, Robyn Rikoon. Hellbenders eat primarily crayfish and fish, but have been known to occasionally eat insects, tadpoles, and even other hellbenders (including eggs).

Hellbenders is a cancelled flash animated series created by Zach Hadel and Chris O'Neill. In North Carolina, the hellbender occurs in fast-moving, clean mountain streams in the Ohio and Tennessee drainages. [7][17] Easily distinguished from most other endemic salamander species simply by their size, hellbenders average up to 60 cm or about 2 ft in length; the only species requiring further distinction (due to an overlap in distribution and size range) is the common mudpuppy (Necturus maculosus). The origin of the name "hellbender" is unclear. [6], Due to sharp decreases seen in the Ozark subspecies, researchers have been trying to differentiate C. a. alleganiensis and C. a. bishopi into two management units. Asked by Wiki User. H ellbenders (Cryptobranchus alleganiensis) are extremely large, completely aquatic salamanders native to the eastern United States. Juvenile hellbenders have many predators, including fish, turtles, water snakes, and other hellbenders. Adults average 20 inches (50 centimeters) in length, but can grow up to 29 inches (73 centimeters). Hellbenders play an important role in maintaining the river's ecology and are indicators of high-quality water. [18] Although their eyesight is relatively poor, they have light-sensitive cells all over their bodies. In all 16 states in which they are found, hellbenders are listed as threatened or endangered. While not deadly touching your face, particularly near the eye area after handling one is a poor, and probably painful idea. A subspecies of hellbender, called the Ozark hellbender, is found in a separate population in Missouri and Arkansas. Most of the waste that is dumped into rivers is acidic. Since so much pollution is dumped and pumped into streams, many hellbenders are dying. Although sometimes confused with mudpuppies, hellbenders are easily distinguished by their lack of external gills. [26] When chytridiomycosis killed 75% of the St. Louis Zoo's captive hellbender population between March 2006 and April 2007, tests began to be conducted on wild populations. [31][32] The legislation did not pass in 2018, but was reintroduced in 2019. Reaching four to five pounds (1.8 to 2.3 kilograms), the hellbender is the largest salamander in North America by weight. The Game Commission of Pennsylvania does dispel another myth about hellbenders. Answer. Hellbenders are the largest salamanders in North America and are of great interest to park rangers in the Hiwassee River area. Directed by J.T. Hellbender populations have declined throughout most of the species’ historic range. Battle Looms Over Pa Staet Amphibian: Hellbender vs. Wehrle's", 10.2305/IUCN.UK.2004.RLTS.T59077A11879843.en, "Snot Otters Get A Second Chance In Ohio", "Pennsylvania Names Water-Lovin' Salamander as State Amphibian", Eastern Hellbender Status Assessment Report, "Notes on the Amphibians of Venango County, Pennsylvania", "U.S. Hellbenders live mostly solitary lives. [33] On April 23, 2019, Pennsylvania Governor Tom Wolf signed legislation making the eastern hellbender Pennsylvania's official state amphibian. [15], Hatchling hellbenders are 25–33 mm long, have a yolk sac as a source of energy for the first few months of life, and lack functional limbs. They have a good sense of smell and move upstream in search of food such as dead fish, following the trail of scent molecules. “So historically, hellbenders occurred in about 15 states and probably across more than 500 streams,” says Bill Hopkins, a professor at Virginia Tech who studies hellbenders. “So historically, hellbenders occurred in about 15 states and probably across more than 500 streams,” says Bill Hopkins, a professor at Virginia Tech who studies hellbenders. Where Hellbenders Live Hellbenders are a fully aquatic species of salamander! [6], The Ozark hellbender has been listed as an endangered species under the Endangered Species Act by the US Fish and Wildlife Service since October 5, 2011. [28], Apart from the Ozark efforts, head-starting programs, in which eggs are collected from the wild and raised in captivity for re-release at a less vulnerable stage, have been initiated in New York[29] and Ohio.[30]. When hellbenders are about two years old, the gills disappear and they start breathing entirely through their skin. This could be reason enough to ensure work is done on both subspecies, as preserving extant genetic diversity is of crucial ecological importance. But where you see one, you know the stream is healthy since they require extremely clean, fast-moving water in order to thrive. Incubating males rock back and forth and undulate their lateral skin folds, which circulates the water, increasing oxygen supply to both eggs and adult. Where does a Hellbender live? Members of the Pennsylvania State Senate have voted to approve the eastern hellbender as the official state amphibian in an effort to raise awareness about its endangered status. Adults have few predators, but may be eaten by raccoons, minks, and river otters. With its large, gaping mouth, the hellbender can eat an animal that is almost as big as itself. They exhibit no sexual dimorphism, except during the fall mating season, when males have a bulging ring around their cloacal glands. The Ozark hellbender subspecies lives only in parts of Missouri and Arkansas. [18][19][8], The small eyes and loose skin are characteristic of hellbenders, The genus Cryptobranchus has historically only been considered to contain one species, C. alleganiensis, with two subspecies, C. a. alleganiensis and C. a. Their range generally covers the Appalachian Mountains, from southern New York to North Georgia. Some smaller populations of Hellbenders can be found in parts of Oklahoma and Kansas. Hellbenders live in flowing streams with a rocky bottom, which provides a place to hide. They also seem to have an individual home range of about 100 square meters, which they tend to defend. [15], Hellbenders are superbly adapted to the shallow, fast-flowing, rocky streams in which they live. Range: The White River watershed in Arkansas and Missouri is home to Ozark hellbenders. Instead of looking for whole animals, scientists use eDNA to check for the presence of hellbenders through the presence of genetic material released by hellbenders into streams through loose skin cells or waste. where do hellbenders live. Mayasich, J.; Grandmaison, D.; Phillips, C. (June 2003). They also have a lateral line similar to those of fish, with which they can detect vibrations in the water. Larvae are about an inch (2.5 centimeters) long and have external gills. Reaching up to 29 inches (74 cm) in length, the hellbender is the largest amphibian in North America, and the fourth-largest in the world. Amphibians for Sale. It is blotchy brown or red-brown in color, with a paler underbelly. The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. Cannibalism—mainly on eggs—has been known to occur within hellbender populations. But during the fall breeding season they have been found in congregations of a dozen or more. The film stars Clifton Collins Jr., Clancy Brown, Andre Royo, Robyn Rikoon, Macon Blair and Stephen Gevedon. [6], Some hellbender populations—namely a few in Missouri, Pennsylvania, and Tennessee—have historically been noted to be quite abundant, but several man-made maladies have converged on the species such that it has seen a serious population decline throughout its range. Fish & Wildlife Service. When a female approaches, the male guides or drives her into his burrow and prevents her from leaving until she oviposits. Hellbenders typically live under large rocks or boulders that are partially buried in cold, fast-flowing streams. Submitted photo; Eastern hellbenders being raised in a lab at Purdue. Both males and females grow to an adult length of 24 to 40 cm (9.4 to 15.7 in) from snout to vent, with a total length of 30 to 74 cm (12 to 29 in), making them the third-largest aquatic salamander species in the world (after the Chinese giant salamander and the Japanese giant salamander, respectively) and the largest amphibian in North America, although this length is rivaled by the reticulated siren of the southeastern United States (although the siren is much leaner in build).
