Animal Diversity The number of animal varieties familiar to us is vast as the animal world is diverse. Each distinct variety or type of animals is recognized by scientist as a species. Animals of most species are free-living forms but of others are parasitic in bodies of other animals or even plants. According to their habitats animals are divided into the following types Aquatic animals :- They live in water . Animals living in sea water are called marine & those live in river‚ponds‚streams
