Animals are classified into different categories based on their characteristics and features. These categories include: Phyla A taxon that groups animals with a common and distinguishing feature. For example, ants are classified into Phylum Arthropoda because they have eight or more legs. Chordates and Non-chordates The animal kingdom is divided into these two major groups. Invertebrates and Vertebrates Animals are classified as invertebrates or vertebrates based on their body complexity. Chordates A phylum of animals that includes vertebrates and some invertebrates.

Invertebrates and Vertebrates Animals are classified as invertebrates or vertebrates based on their body complexity. Chordates A phylum of animals that includes vertebrates and some invertebrates. Chordates are distinguished by having a spinal cord or backbone. Vertebrates Animals that have a spine. Vertebrates can be organized into five classes: mammals, birds, fish, reptiles, and amphibians. Other animal classifications include: Mollusca An invertebrate classification of the animal kingdom. Mollusca have a soft body that is enclosed in a hard shell, and they move with the help of a muscular foot. Platyhelminthes Also known as flatworms, these are unsegmented acoelomates, which means they lack a hollow cavity that protects their internal organs. Porifera A phylum of animals that includes sponges. They are mostly marine animals, but there are a few freshwater species. Show less
