Summary Introduction
In the history of biology, various taxonomist like Carl Linnaeus identified that animals possess a limited number of different body plans. Animals move, feed, and behave in different ways. Certainly, animals have evolved into a variety of structure in order to perform various functions. For example, sponges that lack muscle cells, and they are not able to move from one place to another and rooted to the ground.
