The following phylogeny consists of a well-accepted phylogenetic layout of animals, going until extant families or as far as required by articles on this site. If you are looking for an article by phylogenetic placement of an organism, just select down to the appropriate level.

To recollapse a portion of the tree, just click on it again. A "?" in front of a name indicates that its phylogenetic placement is uncertain, and a dagger (Extinct) indicates that the node and all its descendants are extinct.
