 about the classification of animals, you can learn a lot about animals. Let's get a brief description of the classification of animals for kids. Over 75% of all species on Earth are animals. These animals are categroized into vertebrates and invertebrates. Vertebrates is the group of animals that have back bone while invertebrates is a group of animals that dont have back bone. According to certain traits, vertebrates are further classified into five groups named as amphibian, birds, fish, mammals and reptiles. Here we will discuss these animals and their certain characteristics with examples.

 Amphibians:

 The meaning of the term amphibian is “double life” and refers to vertebrates that live both on land and in water. Amphibians are classified as cold-blooded animals which means they can adjust their body temperature according to the environment. Living in water, they breath with their gills while on land they breathe by lungs. Most amphibians lay their eggs in the water. Before developing into adults, the young go through a larval stage where they breathe through gills and swim with fins. Amphibians do not drink water; rather, they take it in through their skin. Examples of Amphibians

 ● Frogs and toads 

● Salamander and newts 

● Wormlike Birds Although every bird has a backbone but unlike the majority of other vertebrates, birds have a lighter skeletal system that is filled with hollows, gaps, and air sacs to keep them lightweight that improve their ability to fly.
