- Amphibians. Amphibians include frogs, toads, newts, salamanders and the curiously worm-like caecilians. Although most transform from aquatic larvae to terrestrial adults, some amphibians, such as the golden alpine salamander, live permanently on land, while others, such as the axolotl, never leave the water.Sadly, around 41 percent of amphibians are at risk of extinction.lthough most transform from aquatic larvae to terrestrial adults, some amphibians, such as the golden alpine salamander, live permanently on land, while others, such as the axolotl, never leave the water.

Amphibian Modern amphibians are all Lissamphibia. They inhabit a wide variety of habitats with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.mphibians have a skeletal system that is structurally homologous to other tetrapods, though with a number of variations. They all have four limbs except for the legless caecilians and a few species of salamander with reduced or no limbs.

- 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 amenity egg evolved by  reptiles are further adaptations for life on land and distinguish  reptiles from amphibians.he skin in the mouth of some amphibians works the same way as their skin and allows them to respire (You can see this when they allow air flow-it looks like they're breathing normally but in their throat). Long powerful legs that allow it to jump and swim very well.

- The lungs and breathing tubes enabled them to breathe air. Their sternum formed a bony shield that supports and protects the internal organs, especially the lungs. Their hearts have two atriums and one ventricle. The three groups of amphibians alive today are salamanders, frogs and toads, and caecilians.Objectives: - Students will learn to describe what an amphibian is and summarize the events on their evolution by observation and instruction.- Students will learn how amphibians are adapted for life on land and the name of the three main groups of living amphibians by visualization and explanation.he lungs and breathing tubes enabled them to breathe air.

Salamander Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All present-day salamander families are grouped together under the scientific name Urodela. Salamander diversity is most abundant in the Northern Hemisphere and most species are found in the Holarctic ecozone, with some species present in the Neotropical zone. Salaman

Amphibian The three modern orders of amphibians are Anura (the frogs and toads), Urodela (the salamanders), and Apoda (the caecilians). The number of known amphibian species is approximately 7,000, of which nearly 90% are frogs.The smallest amphibian (and vertebrate) in the world is a frog from New Guinea (Paedophryne amauensis) with a length of just 7.7 mm (0.30 in).mphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed.

- Fun Facts: The three-toed amphiuma is likely to play the role of top predator in many aquatic systems. Amphiuma predators include cottonmouths, alligators, and mud snakes. They are able to defend themselves from both predators and people with a powerful bite.hese elongated salamanders may reach more than three feet (.9 m) in length. They are permanently aquatic, although the adults lack gills and use lungs to breathe air. The skin is very smooth and extremely slippery. Both forelimbs and hindlimbs are highly reduced in size and appear nonfunctional.

- 1 Amphibians are cold-blooded (ectothermic) vertebrates that cannot maintain body temperature through their internal physiological procedures. 2  They have a low metabolic rate which leads to a limited requirement for food and energy.  All the species have movable eyelids as well as tear ducts during the adult phase.

Wonderfully Unusual Characteristics of Amphibians Amphibians are vertebrate animals residing in a wide range of habitats, such as aquatic, terrestrial, and arboreal. Evolution of the earliest amphibians took place in the Devonian period; their features modified over a period of time. While some are extinct, following are the characteristics of the extant species of class Amphibia. » The color of the skin of amphibians is a result of three layers of cells called chromatophores. 1  Deepest layer is made up of melanophores. 2  Intermediate layer consists of guanophores giving the organism the blue-green color.  Topmost layer consists of lipophores, which give the yellow color to the organisms.

- Reptiles include alligators, crocodiles, turtles, and snakes. Amphibians include salamanders, toads, and frogs. One difference between the two is the structure of their outer skin. Reptiles are covered with scales, shields, or plates, and their toes have claws.Amphibians, on the other hand, have moist, glandular skins, and their toes lack claws.mphibians are animals that can live on land or in water. They spend part of their lives under water breathing through gills and part of their lives on land breathing with lungs. Amphibians are characterized by glandular skin and no scales.
