Many begin life with gills, then develop lungs as they age. They are vertebrate animals that include frogs, toads, salamanders, and newts as well as odd, wormlike caecilians (seh-SILL-yuns). They are cold-blooded, using the environment to regulate their body temperature. Early amphibians were the first animals to leave the sea and venture onto land, forming a crucial link from fish to terrestrial reptiles. Want to see more of these incredibly colorful critters?

   Extractions: Amphibians are vertebrates that spend part of their lives under water (breathing with gills) and the remainder on land (breathing with lungs). Amphibians are cold-blooded; their body temperature depends on the temperature of their environment. There are three groups (orders) of living amphibians: newts and salamanders (urodeles); frogs and toads (anurans); and caecilians (the worm-like gymnophiones).

5. Amphibians
   Notes on the habitats and distribution of amphibians, their classification, their structure and function, life cycle and behavior.  
   http://www.webspawner.com/users/petcentralamphibians/
   
   Extractions: 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.

Some not-so-familiar creatures, like the legless, burrowing caecilians, are also amphibians. As suggested by their name, which means "double life" in Greek, amphibians spend at least part of their lives in water; some are entirely aquatic.

    Extractions: Amphibians lay their eggs in water, and young amphibians tend to resemble small fish. The tadpole, or newborn frog, is born and lives in water. It has a tail that allows it to swim like a fish. It also has gills so that it can breathe under water.

Visiting the San Diego Zoo and the Wild Animal Park helps provide resources to track, and hopefully slow down, the global decline of amphibian populations. A major cause of the current global amphibian extinction crisis seems to be the spread of the infectious chytrid fungus. This disease grows on the skin of adult amphibians, keeping them from absorbing water and oxygen through their skin. Our researchers will be developing guidelines for disease surveillance, perfecting techniques to freeze amphibian cell cultures for the , collecting and storing sperm, eggs, and embryos from animals within our collection, and managing assurance colonies of amphibians on-site, including our local mountain yellow-legged frog.

All reptiles have scales, but some are too small to be seen. Reptiles are ectothermic (their body temperature is regulated by their environment). Most lay eggs, but a few give birth to live young.

    Extractions: Amphibian populations are disappearing from habitats all around the world. The crisis caught us by surprise - and only now are we able to fully grasp the scope of the situation. Around a third of amphibian species are threatened with extinction - mass extinctions of this magnitude have not been seen since the time of the dinosaurs. The crisis shows us that the world has changed. Traditional threats to species and ecosystems - such as habitat loss and pollution - are being compounded by new threats such as climate change and emerging disease. This is not simply an amphibian problem, but a human welfare issue. We need to act quickly to save the amphibians and the ecosystems that support them and provide us with clean drinking water, clean air, and support the quality of life that many take for granted. Our Response... A unified global response is required to tackle a crisis of this magnitude. This called for the formation of a global body that could harness the intellectual and institutional capacity of a conservation and research network at country, regional and global levels: the Amphibian Specialist Group.
