Mudpuppies , for example, retain juvenile gills in adulthood. The three modern orders of amphibians are Anura (frogs and toads ), Caudata (salamanders and newts ), and Gymnophiona (caecilians, limbless amphibians that resemble snakes). Like the fish they evolved from, most amphibians lay eggs in water. Amphibians are superficially similar to reptiles , but reptiles are amniotes , along with mammals and birds.

3. Amphibian Care Care sheets about amphibian and turtle species, links, pictures of many amphibians. http://www.amphibiancare.com/

While a tree frog or gecko may not make the most traditional pet, the rewards of keeping amphibians and reptiles in captivity are great. Their behavior can be fascinating to observe, and through understanding their captive care requirements you may unintentionally learn about water chemistry, the natural history of a distant place, or the aesthetics of terrarium design. Amphibian Care is a collection of articles, care sheets, photographs, and resources related to the care and understanding of reptiles and amphibians in captivity. For nearly 20 years I have been keeping herpetofauna in glass boxes, and I use this website as a medium through which to share what I have learned with others who have a similar interest. Please realize that there are many ways to care for an amphibian or reptile. The information on this website is presented as general guidelines to follow, not strict rules. Consider spending time visiting other sites, reading books, and talking to fellow herp enthusiasts to further discover new ways to care for your pets. Last update November 1st, 2009

Amphibians NAVIGATOR Home Reptiles Mammals Amphibians ... Birds Amphibians: Frogs Amphibians are members of the class Amphibia, subphylum Vertebrata, phylum Chordata. The class Amphibia includes frogs, toads, salamanders, newts and caecilians. Amphibians are characterized by a glandular skin without external scales, by gills during development (and in adulthood in some), and by eggs that may have jelly coats but develop without formation of extraembryonic membranes such as the amnion. Most amphibians also have four limbs. Limbs and lungs are adaptations for life on land; the limbs evolved from the ancestral fishes' lobed fins. The scales and amniote egg evolved by reptiles are further adaptations for life on land and distinguish reptiles from amphibians. The class Amphibia comprises three living orders and several extinct ones. The living members of the class include those forms which have been mentioned above. Amphibians are thought to have arisen from lobe-finned crossopterygian fishes. Considerable conjecture exists, however, as to whether amphibians actually arose from several lineages. Some Swedish experts tend to favor separate lineages for each of the modern orders; certain British and U.S. scientists support the idea of two lineages, one giving rise to frogs, the other to salamanders and caecilians. The characteristics of vertebrae, teeth, and skull bones form the basis for these hypotheses. Additional developmental and variational data are necessary to support these ideas. Two major subclasses of extinct amphibians are found in the fossil record. They are the Labyrinthodontia and the Lepospondyli. The amphibians of the Labyrinthodontia, which lived during the late Devonian through Triassic periods (345 to 190 million years ago), include the most primitive amphibians represented by the genus Ichthyostega. They were fresh-water carnivorous animals, with tail fins, small scales, and a fishlike vertebral column. Their skulls had many bones, as did those of their presumed crossopterygian ancestor. The Labyrinthodontia, according to the U.S. paleontologist Alfred S. Romer, include three extinct orders: the Ichthyostegalia, the Temnospondyli, and the Anthracosauria. The Anthracosauria are thought to be the ancestors of reptiles and hence of modern birds and mammals. The Temnospondyli are thought by some scientists to be the ancestors of the modern frogs.

AMPHIBIANS - SLIMY IS GOOD Most of the amphibians are slimy. They have a very good reason. Amphibians are the evolutionary step that happened when animals left the oceans and lakes and came on to land. Some fish (lungfish) can survive out of the water for a while, but amphibians were designed for it. One hitch: they need the water when they are kids. Amphibians also use their skin to absorb oxygen from the air. The absorption process is more efficient when the skin is moist all of the time. FROGS AND TOADS It's hard for us to explain what a frog or a toad is. It has four legs. Most amphibians also have moist skin (toads do not) for absorbing oxygen. They have extensions that are like fingers and toes. Like all amphibians, they have a three-chambered heart. We do want to tell you that frogs (and amphibians in general) are dying off. Since they have moist skin that helps them breathe, they are very vulnerable to poisons. Man's pollution is one of the deadliest poisons of all. As we create more pollution, the delicate way that amphibians breathe is being upset. They are slowly dying off. Unfortunately, they live in areas man may not be, so we will never know. SALAMANDERS Salamanders are like frogs, but their body shape is more like a lizard. They are longer and have shorter legs. Often their bodies lay flat on the ground because their limbs (legs) are attached on the side of their bodies, not underneath as in mammals. You will often find salamanders around ponds and other small bodies of fresh water.

Amphibians are cold-blooded; their body temperature depends on the temperature of their environment.

AMPHIBIAWEB Home Search the Database About Amphibians Declines ... Site Map Amphibian Facts Did you know? There are three types of amphibians: 1) Frogs (Anura), 2) Salamanders (Caudata), and 3) Caecilians (Gymnophiona). For more info see Species Numbers The largest genus of frogs is Pristimantis . There are more than 400 species in this genus, with more being described each year (get the latest number by querying the AmphibiaWeb database). These frogs occur in northern South America, mostly in the Andes, with some species found in southern Central America. They are small frogs whose eggs are laid on land and develop directly into small froglets, bypassing the tadpole stage. The largest genus of salamanders , with more than 80 species (get the latest number by querying the AmphibiaWeb database), is Bolitoglossa (the "web-footed salamanders"). Members of this genus are found from Mexico throughout Middle America and most of South America to central Bolivia. These are salamanders that lack an aquatic larval stage, are terrestrial rather than aquatic as adults, and frequently are arboreal. The best known species is probably Bolitoglossa pesrubra , common in the highlands of Costa Rica, where it has been seen by many biologists taking the classes of the Organization for Tropical Biology.

When you are done with this section, take the Amphibians Quiz Amphibians are one of the classes of chordates. The word amphibian means both sides of life. This is because the amphibian begins its life in the water and then finishes it mainly on land. The change of an animal in its appearance from baby to adult is called metamorphosis . An amphibian goes through metamorphosis as it grows from a baby to an adult. The amphibian, because it must be moist, sometimes hides out in the summer as if hibernating. This is called estivation . It also buries itself in the mud during the winter and hibernates to prevent it from freezing as it is cold blooded. Common amphibians include frogs, toads and salamanders. They are, on the whole, quite small vertebrates. System Type Amphibians System Muscular-Skeletal An amphibian has an inner skeleton with a backbone. It has webbed feet, but no claws. They have attached limbs at the shoulders and hips. With the frog and toad, the front legs are shorter and weaker and the rear legs much stronger for leaping. Digestion An amphibian takes in food through the mouth. The frog has a long tongue that it whips out and grabs insects with. It has a digestive system with stomach, intestines.
