Classification of Animal Kingdom - Porifera, Coelenterata, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Chordata.] Since then, animals have evolved into a highly-diverse kingdom. Animal evolution began in the ocean over 600 million years ago with tiny creatures that probably do not resemble any living organism today. Some protest species called choanoflagellates closely resemble the choanocyte cells in the simplest animals, sponges. Animal Phyla-Biologists recognize about 36 separate phyla within the Kingdom Animalia. Most animals are capable of complex and relatively rapid movement compared to plants and other organisms.
