Amphibians are members of the class Amphibia, whose living forms include frogs, toads, salamanders, newts and caecilians.

* Subclass Lissamphibia ( all modern amphibians including frogs, toads, salamanders, newts and caecilians )

*** Order Caudata or Urodela ( salamanders, newts ): Jurassic to present — 571 current species in 10 families

* Lissamphibia: frogs and toads, newts and salamanders, and caecilians

__NOTOC__Herpetology is the branch of zoology concerned with the study of amphibians ( including frogs, toads, salamanders, newts, and gymnophiona ) and reptiles ( including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras ).

Occasionally bats, newts and salamanders, and even fish are eaten.

Living amphibians fall into one of three orders — the Anura ( frogs and toads ), the Caudata or Urodela ( salamanders and newts ), and the Gymnophiona or Apoda ( the limbless caecilians ).

Salamandridae is a family of salamanders consisting of true salamanders and newts.

In the past three decades, declines in populations of amphibians ( the class of organisms that includes frogs, toads, salamanders, newts, and caecilians ) have occurred worldwide.

), eastern newts ( Notophthalmus viridescens ), brook salamanders ( Eurycea spp.

This region of Poland houses species like: cranes, common goldeneyes, goosanders, western marsh harriers, ruffs, kingfishers, trouts, common vipers, fire salamanders, tree frogs and great crested newts.

Trout, salmon, newts and salamanders inhabit the area's streams, and Bullfrog Pond hosts sunfish, Black Bass, and bullfrogs.

The Caudata (" urodeles "; salamanders and newts ), an order of tailed amphibians, is possibly the most adept vertebrate group at regeneration, given their capability of regenerating limbs, tails, jaws, eyes and a variety of internal structures.

Amphibian species frequenting the Audubon Society pond include rough-skinned newts, Pacific tree frogs, and salamanders.

This gallery showcases salamanders, newts, frogs, and toads to display their amazing adaptations and biology.

The zone supports five species of frogs, three species of toads, and five species of newts and salamanders.

In newts, there is no true metamorphosis because newt larvae already feed as predators and continue doing so as adults.

Handling the newts does not cause harm but ingestion of even the most minute amounts of the skin is deadly.

The closed ecology of a space station is satirized in Ethan of Athos, with the emphasis on preventing microbial contamination, the air supply dependent on algae and newts, the processing of dead or contraband animals ( and one dead human ) into vat meat supplies, and the storage of garbage in the vacuum outside the station.

The skin lacks scales and is moist and smooth to the touch, except in newts of the Salamandridae which may have velvety or warty skin that is dry to the touch.

In newts when the lens is removed, pigmented epithelial cells dedifferentiate and then redifferentiate into the lens cells.

Outside the main park there is a nature reserve with hides to watch the wildlife, and dragonfly lakes in which large species of dragonfly live along with newts, frogs and toads.

In the case of newts the process of amplexus is often observed soon after the newts become seasonally active.

There he met the biologist and psychologist Gustav Wolff who had begun experiments on the embryological developments of newts and shown that, if the lens of a developing newt's eye is removed, it regenerates.

Those with a more thoroughly aquatic lifestyle are referred to as " newts ", but this is not a formal taxonomic description.

Head can easily be above or below water: this is a slow but very sustainable stroke, common in turtles and newts.

Tung-Lung Stream is rich in varieties of rare local wild plants and animals, especially in the primeval forest at upper stream, among them the unique Hong Kong newts ( Paramesotriton hongkongensis ) as well as several species of wild orchids.

Among animals and amphibians, there are only newts ( Smooth Newt and Great Crested Newt ), vipers, common lizard, frogs and toads ( common frog, common toad and Moor Frog ) and mice – the island is too small for larger animals which are abundant in the area.

The lake at Bayfordbury was created by the Baker family in 1772 and is now managed for its newts, crayfish and pure genetic stock of Crucian carp.

It is the biggest and least common of the three newts found in the British Isles and is one of only four amphibians which are protected by the UK Biodiversity Action Plan.

This runs along their backs, then a separate smoother-edged crest runs above and below the tail ( in some other species of newts the crest along the back is continuous with the tail crest ).

Breeding is similar to that of other newts.

The newts normally return to the same breeding site each year, and can live as much as 27 years, although up to about 10 years is more usual.

There are fishing ponds between Clemency and Fingig as well as a marshy nature reserve, the Neidriesch, where there is a colony of crested newts, a protected species.

Limb regeneration in newts occurs in two major steps, first dedifferentiation of adult cells into a stem cell state similar to embryonic cells and second, development of these cells into new tissue more or less the same way it developed the first time.

During the breeding season, male smooth newts develop a continuous wavy ( rather than jagged ) crest that runs from their head to their tail, and their spotted markings become more apparent.

* The Cave: a beautifully sculpted life-size model of a cave, featuring more than a dozen small exhibits including snakes, bats, and newts.

Shoreward-bound eastern newts will orient themselves quite differently under light with wavelengths of ~ 400 mm than light with wavelengths of ~ 600 mm, while homing newts will orient themselves the same way under both short and long wavelengths.

* ponds to attract frogs, newts, toads, dragonflies, and birds

Elephant Odyssey's other animal exhibits include African lions, jaguars, Baird's Tapirs, guanacos, capybaras, Kirk's Dik-diks, secretary birds, dung beetles, water beetles, desert tarantulas, toads, newts, turtles, frogs, dromedary camels, pronghorn, horses, burros, llamas, rattlesnakes, and for the first time at the Zoo, the California condor.

The diet of the fire salamander consists of various insects, spiders, earthworms and slugs, but they also occasionally eat newts and young frogs.

It feeds on crustaceans, aquatic insects, frogs, newts and very small fish ignored by larger waders.

The Dragonfly Pond was built to encourage dragonflies and damselflies, and many other plants and animals such as frogs, toads and newts can be found there too.

Firebelly newts should never be kept with dwarf or clawed frogs, as these animals are known carriers of chytrid, a skin fungus that is generally fatal to most amphibian species.

Other sources of food include frogs, tadpoles, newts, minnows, snails, and fairy shrimp.

Additionally, there are frogs, newts, dragonfiles, damsel flies, and the rare bluetailed damselfly, which is used as the quarry's symbol.
