    Simple explanation of amphibians in the framework of the history of the Universe  
    http://www.historyoftheuniverse.com/amphibia.html
    
    Extractions: Once the plants and arthropods were living on land there was plenty of food for any vertebrate which could manage to come out of the water. Some fish lived in ponds which dried up in summer. Their swim bladders evolved into lungs which they used to breathe air. They used their fins to crawl from one pond to another and these evolved into legs, two at the front and two at the back. The vertebrates which emerged from the water and became land animals around 350 million years ago we call amphibians "am-fib-ee-ans". Their name means "both lives" because they lived both in water and on land at different times in their lives. Leaving the water was one of the greatest steps ever taken by our ancestors. It needed changes in every part of the body. The most obvious changes were the appearance of legs and the ability to breathe. Other changes were not so obvious but were just as important. For example the way the blood flowed round the body had to change.

Amphibian larvea are often aquatic and go through a complex metamorphosis process as they grow to adulthood. They have moist skin and do not have scales, feathers or hair. Caecilians (1) Frogs and Toads (6) Newts and Salamanders (1) Amphibians include frogs, toads, caecilians, newts and salamanders. Amphibians are the descendents of the first vertebrates to make the move from life in water to life on land. Despite their early colonization of terrestrial habitats, most lineages of amphibians have never fully severed their ties with aquatic habitats. zSB(3,3) Amphibians were the first vertebrates to make the move from life in water to life on land.

About the Animals Amphibians choose from the links below for animals found at the Zoo: There are more than 6,000 species of amphibians living today. This animal class includes toads and frogs, salamanders and newts, and caecilians. Almost all amphibians have thin, moist skin that helps them breathe. No other group of animals has this special skin. Most amphibians undergo a unique change from larvae to adults, called metamorphosis. All amphibians are ectotherms (what used to be called "cold-blooded"), a trait they share with invertebrates, fish, and reptiles. Most amphibians have thin skin that is very permeable (allowing liquids and gases to pass through it easily). This is important for two reasons. First, it means that their skin helps them breathe, since oxygen passes easily through it. Second, it means that amphibians lose a lot of water through their skin. This is why most amphibians are found in moist or humid environments, where they can re-load their water reserves. The word amphibian comes from the Greek word amphibios , meaning "a being with a double life." Some say their name refers to the fact that amphibians live in two places on land and in water. While dual residence

    Extractions: frogs, toads, salamanders and caecilians. The word means double lifemany species spend part of their life in aquatic (water) and terrestrial (land) environments. Because their skin lacks a shell, scales or outer drier covering, most amphibians live in wet or damp situations to prevent dehydration. Did you know metamorphosis is when... various animals undergo major changes in their body appearance and structure as they grow. They undergo meta (change) in their morpho (form). For instance, frogs lay eggs which grow into tadpoles, which undergo a dramatic change into froglets and finally grow to be an adult frog. The key thing in metamorphosis is a rapid, drastic change in form, for example from the tadpole to the frog. Butterflies are another example of animals that undergo metamorphosis, from a caterpillar to a flying butterfly. Did you know a bio-indicator is...

    Extractions: Gymnophiona (or Apoda) Amphibians (class Amphibia ) are cold-blooded tetrapods (four-legged vertebrates ) whose eggs lack a tough protective membrane around the embryo. The term "amphibian" comes from the Greek amphi meaning "both" and bios meaning "life," hence, "double life." This reflects the fact that most amphibians are biphasic, having an aquatic stage where they spend part of their time, as well as a terrestrial stage. Many, but by no means all amphibians, undergo a change from an aquatic larval stage in which they acquire oxygen from water and lack limbs, to a four-legged, air-breathing adult form adapted for living on the land. There are about six thousand distinct living species of amphibians. Examples include frogs , toads, salamanders , newts, mudpuppies, and caecilians A highly diverse group of animals with only a core percentage exemplifying the most common defining characteristics, amphibians generally have smooth and naked

They are smooth skinned rather than scaly, usually found near water, and most need to keep their skins wet to live. In their larval form they have gills, which some, like the salamanders, keep throughout life; but they also have lungs enabling them to breathe out of water. Amphibians are vertebrates and have four legs. To learn more about these fascinating creatures, browse the articles listed on this page.

    Extractions: (Tiger Salamander) The mole salamanders (Family Ambystomatidae) are found only in North America. Like other members of the Order Caudata, they have slender bodies, long tails and distinct body regions with arms and legs of about the same size. They superficially resemble the lizards but lack the scaly skin, claws and external ear openings of these reptiles. Adult mole salamanders have stocky bodies and limbs, short broad heads and small eyes. A key characteristic is the absence of a nasolabial groove and the presence of distinct costal grooves. They have smooth skin and the teeth, in the roof of the mouth, are in one transverse row. Their tails are flattened. Males have a swollen vent during breeding and longer tails than females. Adults are nocturnal, terrestrial, and frequent moist locations above and below ground. Mole salamander larvae also have wide heads and large tailfins. Their gills are long and feathery. Like the adults, larvae are carnivorous. Most salamanders are voiceless.
