Word origin: from French classe, from Latin classis They had fish-like appearance, become visible in the Carboniferous period, and became plentiful during the Pennsylvanian period of Palaeozoic Era and extinct at the end of Triassic period of Mesozoic Era. There are about 8100 known living amphibians, which play an important role in ecosystem to maintain many food chains. They also have fins to help them swim, just like fish. This sub-class is further grouped into three orders (I) Order-I – Labyrithodontia: (i) These groups of amphibians are the most primitive tetrapods and oldest known tetrapods. The lateral line is seen during their larval stage. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

Amphibian definition, any cold-blooded vertebrate of the class Amphibia, comprising frogs and toads, newts and salamanders, and caecilians, the larvae being typically aquatic, breathing by gills, and the adults being typically semiterrestrial, breathing by lungs and through the moist, glandular skin. Hind limbs are stout and larger in size with highly muscular which are used for jumping, leaping, and swimming. They are aquatic, semi-aquatic and terrestrial. They have a wet skin and depend greatly on cutaneous as a secondary respiration but some small terrestrial salamanders and frogs  do not have lungs, entirely depend on their skin for their respiration. They were the most primitive tetrapods and oldest known tetrapods, called as stem Amphibia.

External gills are present throughout the entire life. The family  Pelobatidae contains six species in one genus. But larval forms respire through the gills. The body size ranges from 1.6 to 7.5 inches (4 -19 cm) in length. The eggs hatch into larvae which live in leakage in soil or streams. They are found across the globe and range from few millimeters to a feet or two in length. Bufoides meghalayanus, Duttaphrynus melanostictus, Barbarophryne brongersmai, etc. Class- Amphibia.

They lay eggs in ponds, on leaves or in wetlands and marches, or treeholes. Examples: The super class Tetrapoda is divided into four classes namely. Reptiles lay their eggs on land which have a hard protective covering. They are commonly known as Australian water frogs or Australian ground frogs. They are either terrestrial or aquatic frogs. They are distributed in Europe and North America. Protusible copulatory organ is present in the males. They are oviparous and they lay eggs in cavities in moist soil. Due to their life cycle and physiology, many amphibians are “tied” to water in order to survive and reproduce. Difference between Amphibia and Reptilia are stated in the following table: Amphibians are cold-blooded animals which live on land or in water. Fertilization is internal and the female lays eggs on land. Examples:  Crocodiles, Alligators, gavials, lizards, snakes, tortoises, turtles, etc. The body is elongate with up to 60 vertebrae.

Amphibians such as frogs, toads,, salamanders and limbless ones, are cold-blooded animals that metamorphose from water-breathing tadpole to an air-breathing adult. During dry season, they can able to burrow into mud and enclose themselves creating a cocoon of mucus for surviving the drought periods. The three modern orders are Anura (the frogs and toads), Caudata (or Urodela, the salamanders), and Gymnophiona (or Apoda, the caecilians). amzn_assoc_search_bar = "true"; The family Proteidae consists of 6 species in 2 genera.

For example, class Mammalia belongs to phylum Chordata. Reptiles are also cold-blooded animals. They inhabit wide variety of habitats including lakes, rivers and streams or caves. Ribs attached with column between vertebrae. The excretion is ureotelic and the excretory waste products are ammonia and urea. As a volunteer-based monitoring program, FrogWatch gives citizens across the country an opportunity to be directly involved in gathering the information that can ultimately lead to practical and workable ways to help stop amphibian decline. They are egg layers and usually breed in water bodies. Its members are known as caecilians, a name derived from the Latin word caecus, meaning “sightless” or “blind.” The majority of this group of limbless, wormlike amphibians live underground in humid tropical regions throughout the world.
