This document provides an overview of different animal classifications including: - Poriferans and cnidarians which are simple marine animals without backbones or complex tissues. - Echinoderms which move via tube feet and often have spiny coverings. - Annelids which are segmented worms. - Mollusks which often have a protective shell and move using a foot. - Arthropods which have a hard exoskeleton and undergo metamorphosis. - Fish and other aquatic vertebrates which breathe through gills and have fins. - Amphibians which can live on land and water and undergo metamorphosis from eggs to adults. - Rept
