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.
Classification involves grouping organisms into a series of hierarchical categories: kingdom, phylum, class, order, family, genus and species. These categories were first developed by Carl Linnaeus in the 18 th century and have remained in common use ever since. Animals are typically large and multi-cellular. 2  They are heterotrophic and rely on other organisms for food. 3  Animals in the marine environment include jellyfish, sponges, sea spiders, bryozoans, mussels, sea stars, fish and whales.
