[7][8] The species is listed as Near Threatened on the IUCN Red List of Threatened Species.[2]. 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. Meet the Hellbender Salamander . In April 2010 we filed a scientific petition with the U.S. [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. Scientific Name: Cryptobranchus alleganiensis alleganiensis Classification: Amphibian, Order Caudata , Family Cryptobranchidae Relatives: Chinese and Japanese giant salamanders, Ozark hellbender Many of these projects are outlined at Help the Hellbender, which provides information on how anglers, homeowners, farmers and teachers can all lend a hand to help hellbenders. Hellbender at the Toledo Zoo. Natural Habitat. [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]. C. alleganiensis has a flat body and head, with beady dorsal eyes and slimy skin. The hellbender, which is much larger than all other salamanders in its geographic range, employs an unusual means of respiration (which involves cutaneous gas exchange through capillaries found in its dorsoventral skin folds), and fills a particular niche—both as a predator and prey—in its ecosystem, which either it or its ancestors have occupied for around 65 million years. Scientific Name Hellbender: Cryptobranchus Alleganiensis Distribution and Habitat Geographic Range. Fish and Wildlife Service to list 404 Southeast aquatic, riparian and wetland species as threatened or endangered under the Endangered Species Act, including the hellbender. Log in Sign up. This specialization likely contributed to the decline in their populations, as collectors could easily identify their specific habitats. Although both are amphibians, mudpuppies have large external feathery gills. Giant Salamander. Called such unflattering names as “mud devil,” “devil dog” and “ground puppy,” the hellbender salamander is the largest aquatic salamander in the United States, growing as long as 30 inches, though the average is 12-15 inches. Young hellbenders face even more predators, including fish, reptiles, birds, mammals, and even larger hellbenders. [21] Hellbender populations were listed in 1981 as already extinct or endangered in Illinois, Indiana, Iowa, and Maryland, decreasing in Arkansas and Kentucky, and generally threatened as a species throughout their range by various human activities and developments. Range: Southern New York to Northern Georgia 3. Review the Zoo’s reopening guidelines and make a reservation. Taxon: Amphibian 2. [25], Research throughout the range of the hellbender has shown a dramatic decline in populations in the majority of locations. Hellbenders are the largest salamanders in North America and the third largest in the world. [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. [4], The genus name is derived from the Ancient Greek kryptos (hidden) and branchion (gill). They have a good sense of smell and move upstream in search of food such as dead fish, following the trail of scent molecules. [20] At this point, when they are roughly 13.5 cm long, they lose the gills present during their larval stage. They also have a lateral line similar to those of fish, with which they can detect vibrations in the water. The Eastern Hellbender is classified … [18] Their skin is brown with black splotches - perfect for blending in with their surroundings and avoiding potential predators. Scientific Name: Cryptobranchus alleganiensis. Once a hellbender finds a favorable location, it generally does not stray too far from it—except occasionally for breeding and hunting—and will protect it from other hellbenders both in and out of the breeding season. [12] The subspecific name bishopi is in honor of American herpetologist Sherman C. ... Hellbender Cryptobranchus alleganiensis (Sonnini de Manoncourt & Latreille 1801) collect. Those on their tails are especially finely tuned and may help them position safely under rocks without their tails poking out to give themselves away. Weight:5 – 2.5 kg (3.3 – 5.5 lb.) In the 24 missions or levels of Hellbender… SCIENTIFIC NAME: Cryptobranchus alleganiensis alleganiensis. Size: 9-16 inches (24-40 cm) in length. This will help them come up with solutions to save this unique amphibian. [15], Female hellbenders lay 150–200 eggs over a two- to three-day period; the eggs are 18–20 mm in diameter, connected by five to 10 cords. eastern hellbender. 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. Hellbender Facts. We dropped a new album back in July named “American Nightmare”, if you haven’t heard it check it out at www.hellbender707.com or www.NoLifetilMetal.com , you guys can download both of our albums off our website too! [15], Hellbenders are superbly adapted to the shallow, fast-flowing, rocky streams in which they live. Class: AmphibiaOrder: CaudataFamily: Cryptobranchidae. Although their eyesight is relatively poor, they have light-sensitive cells all over their bodies. These amphibians have natural camouflage. Start studying salamanders common and scientific names. Cannibalism of eggs is also considered a common occurrence.[16]. Northern Arkansas and southern Missouri are the home of the endangered Ozark hellbender. Reservations are required to visit. The Zoo is NOW OPEN. [18][16] This demarcation can be made by noting the presence of external gills in the mudpuppy, which are lacking in the hellbender, as well as the presence of four toes on each hind foot of the mudpuppy (in contrast with the hellbender's five). A below-favorable oxygen content can make life equally difficult. Common Name: Eastern Hellbender. After a brief courtship, the female deposits a clutch of eggs - between 200 and 500! They exhibit no sexual dimorphism, except during the fall mating season, when males have a bulging ring around their cloacal glands. Until then, they are easily confused with mudpuppies, and can be differentiated often only through toe number. [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. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Learn amphibian scientific names with free interactive flashcards. 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). [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. They usually don't swim, but they walk on the bottom of the stream bed. A scientific collector's permit is required to legally … Created by Zach Hadel, Chris O'Neill. [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). [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. [34] Youth members of the Chesapeake Bay Foundation's Pennsylvania Student Leadership Council were heavily involved writing and advocating on behalf of this legislation. Like Star Trek - The Next Generation's Borg, the Bions are trying to annihilate humanity. Research throughout the range of the hellbender has shown a dramatic decline in populations in the majority of locations. Cryptobranchus alleganiensis. … This hellbender subspecies inhabits the White River and Spring River systems in southern Missouri and northern Arkansas, and its population has declined an estimated 75% since the 1980s, with only about 590 individuals remaining in the wild. In the fall, a male hellbender sets up a nesting site under a large stone and waits for a willing female to enter. mudpuppy. Eastern Hellbender. Etymology: Genus: Cryptobranchus is derived from the Greek and means "hidden gills". These groups are working together to learn what's causing the hellbender's rapid population decline. Learn more by reading the Eastern Hellbender species profile. [15], After oviposition, the male drives the female away from the nest and guards the eggs. Many different anthropogenic sources have helped to create this decline, including the siltationand sedimentation, blocking of dispersal/migration routes, and destruction of riverine habitats created by dams and other development, as well as pollution, disease and overharvesting for commercial and scientific purposes. The species is at least somewhat nocturnal, with peak activity being reported by one source as occurring around "two hours after dark" and again at dawn (although the dawn peak was recorded in the lab and could be misleading as a result). Preferred Names. Eastern Hellbender. 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. Eastern Hellbender Status Survey. With Chris O'Neill, Zach Hadel, Mick Lauer, Joshua Tomar. Learn more about the Eastern Hellbender by clicking the link below! Hellbenders can be seen at the Herpetarium. Second generation, captive-bred Ozark hellbenders have hatched at the Saint Louis Zoo this October, a historic achievement in conservation for this endangered species. It will continue to grow for many years to come. Hellbenders typically live under large rocks or boulders that are partially buried in cold, fast-flowing streams. [15], The hellbender has a few characteristics that make it distinguishable from other native salamanders, including a gigantic, dorsoventrally flattened body with thick folds travelling down the sides, a single open gill slit on each side, and hind feet with five toes each. Scientific Name: Cryptobranchus alleganiensis. The hellbender is mature at about 6 to 8 years of age, at which time it is about 1 foot long. Hellbenders face many dangerous predators, but their biggest enemy isn't a wild animal - it's us. The show first premiered on YouTube with a short preview on August 17, 2012.The first official episode of Hellbenders premiered on October 7, 2012. One researcher claimed perhaps density is maintained, and density dependence in turn created, in part by intraspecific predation. Status: Not listed under the Endangered Species ActReferred to by locals as “mud devil”, “devil dog”, “ground puppy”, “snot otter”, “lasagna lizard”, and “Allegheny alligator”, the hellbender has certainly been colored as “a creature from hell where it’s bent of returning.” This large amphibian can be found crawling around the bottoms of clear, silt-free mountain streams. Status: Species of special concern. [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. [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. [22][23], Both subspecies, C. a. alleganiensis and C. a. bishopi undergo a metamorphosis after around a year and a half of life. Hellbender Marketing is named after the Eastern Hellbender, the now state salamander of Pennsylvania. The general public is not permitted to collect hellbenders. Cannibalism—mainly on eggs—has been known to occur within hellbender populations. Adults have to watch out for predators like river otters and raccoons. Flickr/Brian Gratwicke. Incubating males rock back and forth and undulate their lateral skin folds, which circulates the water, increasing oxygen supply to both eggs and adult. Except for the breeding season, hellbenders are solitary creatures, living alone. is one of the largest species of salamanders in the world. [9], Other vernacular names include snot otter,[10] lasagna lizard,[10] devil dog, mud-devil, grampus, Allegheny alligator, mud dog, water dog, spotted water gecko[11][additional citation(s) needed] and leverian water newt. [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. The origin of the name "hellbender" is unclear. Measuring about two feet in length, the hellbender (also known as a "snot otter"!) This refers to the lack of large external gills. More Hellbender Work. emily_taylor570. Meanwhile, the center will create a captive breeding program in case (as a last resort) captive-bred hellbenders are needed for reintroduction to the wild. As part of this effort, the conservation center will assist and support researchers who are studying the water quality of the hellbenders' native habitat in Missouri and Arkansas.

[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. In Hellbender, you pilot a "Hellbender" prototype attack spaceship. bishopi. It is the male who defends the nest for the next 45 to 60 days, until the eggs hatch into larvae (see amphibians.). The Reptile Discovery Center's Appalachian Salamander Lab was established in recent years as an … The disease has been detected in all Missouri populations of the Ozark hellbender. When brainstorming names for our start up company, we wanted our brand to stand out as well as represent our Pennsylvania roots. As the female lays eggs, the male positions himself alongside or slightly above them, spraying the eggs with sperm while swaying his tail and moving his hind limbs, which disperses the sperm uniformly. [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. Hellbender Facts At A Glance. These three groups were shown to be isolated, and are considered to most likely be "diverging on different evolutionary paths". Cannibalism, however, leads to a much lower number of eggs in hellbender nests than would be predicted by egg counts. is one of the largest species of salamanders in the world. Hellbender misses all you guys and can’t wait to see everybody soon! The adventures of two young boys, Chris and Zach, who live … This male and his clutchmates were the result of the world's first successful captive breeding of Ozark hellbenders in November 2011 at the Zoo. What do they look like? [23] While the range of two hellbenders may overlap, they are noted as rarely being present in the overlapping area when the other salamander is in the area. Measuring about two feet in length, the hellbender (also known as a "snot otter"!) The Missouri Department of Conservation says: The name 'hellbender' probably comes from the animal's odd look. Their slippery, flattened body moves easily through water, and their well-developed legs and oar-like tail help them walk against the current with little resistance.
