Animals are defined as eukaryotic organisms that have numerous cells. Their genetic kingdom is referred to as animalia. It is believed that the sum of all animal species is about seven million but only about 1.5 million of them have been discussed. Out of the 1.5 million, approximately one million are insects. Apart from a few exceptional animals, most animals reproduce sexually, consume organic substances, and have the ability to move. In this article, we will focus on animals that start with letter A.

Animal species are generally put into groups according to similarities of certain features. Categorizing animals makes it easier to study them. They can be grouped as vertebrates or invertebrates; those with backbones are referred to as vertebrates and those without are classified as invertebrates. All animals in this world belong to one of the classes. The most common group of vertebrates includes amphibians, mammals, fish, reptiles, and birds while invertebrates include insects and arachnids.
