Animals are simply defined as the multicellular, eukaryotic, aerobic organisms which feed on plants and other animals as their source of food. All these animals reproduce sexually and live freely in the habitat. Altogether, there are two to three millions of animal species and are grouped into the Animal kingdom, which is the largest and most diverse group among the five kingdoms of biological classifications. Based on their similarities, characteristic features, and their genetic analysis, animals are grouped into Kingdom Animalia.
In order to study the different types of animals along with their features, taxonomist grouped all animals into Kingdom Animalia, which is further divided into divisions and subdivisions. Based on their body structure and the presence of the backbone, animals are divided into vertebrates and invertebrates. More than millions of invertebrate species are discovered, whereas only fifty to sixty thousands of different vertebrates are identified.
There are different types of animal species available in Animal kingdom or kingdom Animalia, which are further classified based on the type of cell, body symmetry, types of reproduction, mode of nutrition, their locomotion and their habitat but not classified by their size.
