Due to its ecology , the planet has a large number of living beings and, in turn, they have genetic differences , which allows the development of very varied lives.

For the good and efficient study of the animals, forms of classification were designed, based on their feeding, structure and reproduction.

There are big differences such as those with a backbone and those without. These are called vertebrates and invertebrates .
