Deuterostomes (from Greek: lit. 'mouth second') are bilaterian animals of the superphylum Deuterostomia ( / ˌdjuːtərəˈstoʊmi.ə / ), [3] [4] typically characterized by their anus forming before the mouth during embryonic development.
Deuterostomia, (Greek: “second mouth”), group of animals—including those of the phyla Echinodermata (e.g., starfish, sea urchins), Chordata (e.g., sea squirts, lancelets, and vertebrates), Chaetognatha (e.g., arrowworms), and Brachiopoda (e.g., lamp shells)—classified together on the basis of.

There are a series of other developmental characteristics that differ between protostomes and deuterostomes, including the mode of formation of the coelom and the early cell division of the embryo.
