The Ozark hellbender subspecies lives only in parts of Missouri and Arkansas. Related Questions. C. alleganiensis has a flat body and head, with beady dorsal eyes and slimy skin. [16] An adult weighs 1.5 to 2.5 kg (3.3 to 5.5 lb), making them the fourth heaviest living amphibian in the world after their Chinese and Japanese cousins and the goliath frog, while the largest cane toads may also weigh as much as a hellbender. With its large, gaping mouth, the hellbender can eat an animal that is almost as big as itself. C. alleganiensis has a flat body and head, with beady dorsal eyes and slimy skin. Hellbenders do have lungs but mainly use them to help with buoyancy. Cannibalism—mainly on eggs—has been known to occur within hellbender populations. [20] As a result of this specialization, hellbenders are generally found in areas with large, irregularly shaped, and intermittent rocks and swiftly moving water, while they tend to avoid wider, slow-moving waters with muddy banks and/or slab rock bottoms. All of the rainwater that falls on us here eventually makes its way through the stream and river systems back to the sea. [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. Helbenders are endangered mainly because of pollution. The hellbender’s lifespan in uncertain. [15] After this metamorphosis, hellbenders must be able to absorb oxygen through the folds in their skin, which is largely behind the need for fast-moving, oxygenated water. Clean, fast-moving river water is an ideal habitat. Petty. One report, written by a commercial collector in the 1940s, noted a trend of more crayfish predation in the summer during times of higher prey activity, whereas fish made up a larger part of the winter diet, when crayfish are less active. The subspecies (or species, depending on the source) C. a. bishopi is confined to the Ozarks of northern Arkansas and southern Missouri, while C. a. alleganiensis is found in the rest of these states. In all 16 states in which they are found, hellbenders are listed as threatened or endangered. [15], Hellbenders are superbly adapted to the shallow, fast-flowing, rocky streams in which they live. Amphibians for Sale. Incubating males rock back and forth and undulate their lateral skin folds, which circulates the water, increasing oxygen supply to both eggs and adult. [16] A recent decline in population size of the Ozark subspecies C. a. bishopi has led to further research into populations of this subspecies, including genetic analysis to determine the best method for conservation. These three groups were shown to be isolated, and are considered to most likely be "diverging on different evolutionary paths". [18], Hellbenders are present in a number of Eastern US states, from southern New York to northern Georgia,[20] including parts of Ohio, Pennsylvania, Maryland, West Virginia, Virginia, Kentucky, Illinois, Indiana, Tennessee, North Carolina, South Carolina, Alabama, Mississippi, Arkansas, Missouri, and even a small bit of Oklahoma and Kansas. With Clifton Collins Jr., Clancy Brown, Andre Royo, Robyn Rikoon. Hellbenders is a 2012 American comedy horror film written and directed by J. T. Petty. They like a very specific type of habitat that includes streams and rivers with rapid flowing water. There seems to be a specific temperature range in which hellbenders feed, as well: between 45 and 80 °F. Hellbenders are the subject of many myths, however they are not poisonous when they bite, but they do emit a toxic secretion on their skin.. bishopi. It is the Service’s determination that the Missouri distinct population segment of the eastern hellbender is currently in danger of extinction. People living in those neighborhoods also are exposed to more encounters with … Hellbenders eat primarily crayfish and fish, but have been known to occasionally eat insects, tadpoles, and even other hellbenders (including eggs). We're on the ground in seven regions across the country, collaborating with 53 state and territory affiliates to reverse the crisis and ensure wildlife thrive. When stray pets roam our neighborhoods, it's not only dangerous for the pets but for the people who live there, too. The largest hellbender ever recorded was nearly 2 1/2 ft. long. Be the first to answer this question. [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. Hellbenders do have many, tiny teeth, but they usually don't try to bite. If a hellbender ends up in an area of slow-moving water, not enough of it will pass over its skin in a given time, making it difficult to garner enough oxygen to support necessary respiratory functions. 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. The National Wildlife Federation is providing resources to help families and caregivers across the country provide meaningful educational opportunities and safe outdoor experiences for children during these incredibly difficult times. Juvenile hellbenders have many predators, including fish, turtles, water snakes, and other hellbenders. But during the fall breeding season they have been found in congregations of a dozen or more. Before mating, each male excavates a brood site, a saucer-shaped depression under a rock or log, with its entrance positioned out of the direct current, usually pointing downstream. In 4 seconds, you will be redirected to nwfactionfund.org, the site of the National Wildlife Action Fund, a 501(c)(4) organization. Deer ticks live in shady, moist areas at ground level. Adults spend most of their life under large, flat rocks that shelter them. [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. “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. Hellbenders have been known to grow up to 29 inches long, though most will average about 12-15 inches. Their range generally covers the Appalachian Mountains, from southern New York to North Georgia. [6][8] As many of these detrimental effects have irreversibly damaged hellbender populations, it is important to conserve the remaining populations through protecting habitats and—perhaps in places where the species was once endemic and has been extirpated—by augmenting numbers through reintroduction. [23][20][15], The hellbenders' breeding season begins in late August or early- to mid-September and can continue as late as the end of November, depending on region. The male often tempts other females to lay eggs in his nest, and as many as 1,946[24] eggs have been counted in a single nest. The range for the Eastern hellbender subspecies stretches from New York in the north and east, to Missouri in the west and to Alabama in the south. Be the first to answer! Like most salamanders, it has short legs with four toes on the front legs and five on its back limbs, and its tail is keeled for propulsion. Degraded water quality, habitat loss resulting from impoundments, ore and gravel mining, sedimentation, and collection for the pet trade are thought to be the main factors resulting in the amphibian's decline. The male remains in the brood site awaiting a female. Cannibalism of eggs is also considered a common occurrence.[16]. The Missouri Department of Conservation says: The name 'hellbender' probably comes from the animal's odd look. [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]. Males and females become sexually mature in approximately 5-7 years and can live up to 30 years of age. Another rendition says the undulating skin of a hellbender reminded observers of "horrible tortures of the infernal regions." Hellbenders is a cancelled flash animated series created by Zach Hadel and Chris O'Neill. They have populations in Northern Georgia, Ohio, North Carolina, South Carolina, Kentucky, Alabama, West Virginia, Virginia, and several other states.
