California tiger salamanders face a threat from a hybrid relative as well as from over development and pollution, researchers said. Very little development threatened the amphibians 60 years ago when commercial bait sellers in California imported barred tiger salamanders from Texas, a biologist from the University of California Davis told the San Francisco Chronicle. Maureen Ryan of the Center for Population Biology at UC Davis said the larvae of the new salamanders was popular bait, but the...

The salamander is known for its regeneration, as it can replace lost limbs, lungs, its spinal cord, and even parts of its brain that it has lost. New research says that the unique ability might one day be duplicated by scientists to use in humans. Until now, biologists have credited the regeneration to the salamander's "pluripotent" cells, which surge to the area of amputation, or a blastema, and act like human stem cells in their versatility. Pluripotent cells are persuaded by signals into...

Hope for amputees lies in a strange looking Mexican salamander due to its ability to regenerate body parts. The creatures are called "water monsters." The half-foot-long axolotl is nearly extinct in its only remaining habitat. It's found in ancient Aztec canals that snake though southern Mexico City. The slimy animal is thriving in labs where it reproduces easily. It has the ability to re-grow injured limbs, jaws, skin, organs and parts of its brain and spinal chord. Only salamanders are...

A professor at Tulane University in New Orleans says he is studying a Mexican salamander in the hope of learning how to regenerate human limbs. Ken Muneoka, a cell and molecular biology professor at Tulane, said his research team of biologists from the University of Kentucky and the University of California at Irvine are attempting to learn how the salamander is able to regenerate its limbs, the New Orleans Times-Picayune reported Sunday. What we want to do is a detailed analysis of...

Rare traits persist in a population because predators detect common forms of prey more easily. Researchers writing in the open access journal BMC Ecology found that birds will target salamanders that look like the majority "“ even reversing their behavior in response to alterations in the ratio of a distinguishing trait. Benjamin Fitzpatrick, from the University of Tennessee, worked with Kim Shook and Reuben Izally to study the effects of the prevalence of a dorsal stripe among a group...

The Kansas Herpetological Society is looking for volunteers willing to spend hours searching for animals they might normally avoid -- say, for instance, snakes. The society's planned animal count will cover turtles, lizards, salamanders, frogs and toads as well as snakes, The Emporia (Kansas) Gazette reported. The event is scheduled for April 26 and April 27 in Chase County in eastern Kansas. Lest the actual seeking out these animals sound daunting, consider this: these folks are the...

Bait shop trade likely source of pathogen spread in salamanders Waterdogs, they're called, these larvae of tiger salamanders used as live bait for freshwater fishing. With tiger salamander larvae, anglers hope to catch largemouth bass, channel catfish and other freshwater fishes. They may be in for more than they bargained for: salamanders in bait shops in Arizona, Colorado and New Mexico are infected with ranaviruses, and those in Arizona, with a chytrid fungus called Batrachochytrium...

Although research has linked inbreeding with elevated rates of deformity in a wide variety of animals, a new study finds it plays no part in the high incidence of malformation among salamanders. Purdue University researchers recently examined 2,000 adult and juvenile salamanders and found that 8 percent had visible deformities, mainly consisting of missing, extra or dwarfed digits (equivalent to fingers and toes). That is double the rate of malformation found in newts, a related amphibian,...

A new study found that amphibian populations at Yellowstone National Park are in steep decline. Researchers point to climate change, which is causing the wetlands where animals breed and live to dry out. The park, which stretches over 9,000 sq km in the western U.S., shares land in Wyoming, Montana and Idaho. U.S. congress granted Yellowstone national park status on 1 March 1872. The park's vast forests and grasslands are also home to grizzly bears, wolves and bison. However, all eyes are on...

Reducing the number of deer in forests and parks may unexpectedly reduce the number of reptiles, amphibians and insects in that area, new research suggests. A recent study by researchers at Ohio State University and National Park Service found that higher deer activity is modifying forest ecosystems in unexpected ways. Out of several species of snakes, salamanders, and invertebrates studied, a greater diversity of animals were found in areas with deer populations than were in areas with no...

The California slender salamander (Batrachoseps attenuatus) is a member of the Plethodontidae family of salamander species. The species is native to California and southwest Oregon. The California slender salamander ranges from central California, north along the coast and ranges into Oregon and in the foothills of the Sierra Nevada mountains.

The California giant salamander (Dicamptodon ensatus) is a member of the Dicamptodontidae family. The species is native only to northern California. The California giant salamander inhabits moist, coastal forests or streams, lakes and ponds. Some of the species may remain gilled aquatic creatures, while others transform and become terrestrial land creatures. The California giant is nocturnal and most of its life is spent hiding and burrowing. Typically, the California giant salamander...

The Axolotl, Ambystoma mexicanum
2014-02-03 08:59:54

Axolotl (Ambystoma mexicanum) may also be referred to as the Mexican salamander or the Mexican walking fish. The Axolotl is a member of the Ambystomatidae family and although its common name may suggest it is a fish, it is an amphibian. Axolotl are found exclusively in Mexico. The species situates, near Mexico City, on the bottom of Xochimilco’s lakes. Unlike most salamanders, Axolotl keep its larval features throughout its entire life and very rarely ever emerge from water. A condition...
