Phyla) is the largest formal major grouping within animal taxonomy. This list is presented in alphabetical order, and not in any systematic/evolutionary arrangement. This list is also available in table form. Science is by no means static. There are arguments of all sizes and shapes about the taxonomy of the Animal Phyla.Brachiopods are marine animals belonging to their own phylum of the animal kingdom, Brachiopoda.
