What is Overview of Animalia Classification about?
Animals are multicellular, eukaryotic organisms that develop a fixed body plan as they grow, though some undergo metamorphosis later in life. Most animals can move independently and must consume other organisms for sustenance. The majority of animal phyla first appeared in the fossil record during the Cambrian explosion approximately 542 million years ago as marine species, and animals are divided into subgroups including vertebrates, molluscs, arthropods, annelids, and jellyfish.
