A diverse group of vertebrate animals called amphibians are distinguished by their capacity to coexist on land and in water. They belong to the class of animals known as amphibia, which is made up of many interesting organisms. The various varieties of amphibians are as follows:

Different types of Amphibians

1. Anurans (Order Anura):

The most well-known class of amphibians are anurans, also referred to as frogs and toads.

• They have a distinctive body form with long legs on the back that are used for swimming and jumping.

• In contrast to toads, frogs often have smooth, moist skin.

• Tadpoles of the anuran family undergo a complete metamorphosis, evolving into adults that live on land.

• Frogs often have smooth skin and slim bodies. They are ideally suited for an aquatic lifestyle and have webbed feet.

• Toads are more suited to a life on land and have skin that is rougher and dryer. They frequently move by walking or hopping and have shorter legs.

Caudatans (Order Caudata or Urodela):

Salamanders and newts are caudatans.

·        These amphibians have four limbs, lengthy tails, and elongated bodies.
·        They are unable of jumping like frogs and toads can.
·        While some animals go through metamorphosis to breathe air, many species keep their gills throughout their entire lives.
·        Salamanders and newts resemble lizards because of their long, thin bodies and tails. Their skin is supple and permeable.
·        Salamanders typically resemble their prehistoric forebears by having a more basic body structure. They frequently inhabit areas near bodies of water.
·        A subclass of salamanders known as newts is frequently distinguished by vivid coloration. While some species are terrestrial, others are aquatic.

3. Gymnophionans (Order Gymnophiona):

• Caecilians are another name for gymnophionans.

• They have no legs and resemble snakes or earthworms.

• Tropical areas, particularly those in South America, Africa, and Southeast Asia, are where these amphibians are frequently found.

• They are primarily found in tropical areas, are frequently fossorial, and spend the majority of their lives in burrows or underground.

4. Extinct Amphibians:

• Several different and sizable amphibians previously roamed the earth, including well-known prehistoric species like the enormous amphibian known as the "Diplocaulus."

• Some enormous extinct amphibians that were mistaken for reptiles were amphibians.

There are numerous species of amphibians in each of these groups, each with its own special adaptations and traits.

Physiology

The life cycle of an amphibian is distinctive since it frequently includes both aquatic and terrestrial phases (egg, aquatic larva, and terrestrial adult). Typically, they have a cold-blooded metabolism. Through their skin, which needs to be maintained moist, they breathe. They are consequently more susceptible to pollution and habitat loss due to their heightened sensitivity to environmental changes. Threats to numerous amphibian species today include habitat loss, climate change, and the fungus chytridiomycosis. To preserve these fascinating and crucial to the environment critters, conservation initiatives are in place.
