Classification of animals. All around the world many different types of animals are present. Many animals are quite similar to each other while others are different from others. So animals can be classified based on their similarities. The whole animal kingdom is divided into two main groups. They are Vertebrates and Invertebrates.
Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material. Animal Sizes. Animals range in size from no more than a few cells (like the mesozoans) to organisms weighing many tons (like the blue whale). Animal Habitats. Most animals inhabit the seas, with fewer in fresh water and even fewer on land. Animal Bodies The bodies of most animals (all except sponges) are made up of cells organized into tissues.
