Deuterostomes (from Greek: lit 'second mouth') are bilaterian animals of the superphylum Deuterostomia ( ˌdjuːtərəˈstoʊmi ə ), [3][4] typically characterized by their anus forming before the mouth during embryonic development Deuterostomia comprises three phyla: Chordata, Echinodermata, Hemichordata, and the extinct clade Cambroernida
- Deuterostome - Definition, Types Examples - Biology Dictionary
The Deuterostomes are a clade of animals that undergo deuterostomy during their embryonic development They are a sister-clade of the Protostomes, and the two together with the Xenacoelomorpha form the major group of animals called the Bilateria —a major group animals which display bilateral symmetry and are mostly triploblastic

The word deuterostome comes from the Greek word meaning “mouth second,” indicating that the anus is the first to develop The phyla Echinodermata and Chordata (the phylum in which humans are placed) both belong to the superphylum Deuterostomia

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 embryological development and by molecular criteria
- What are Deuterostomes? (with pictures) - AllTheScience
Deuterostomes are a large superphylum of animals that includes chordates (vertebrates), echinoderms, hemichordates (acorn worms), and one small phyla, Xenoturbellida, which consists of two marine worm-like species

In deuterostomes, the endodermal lining of the archenteron usually forms buds called coelomic pouches that expand and ultimately obliterate the embryonic blastocoel (the cavity within the blastula and early gastrula) to become the embryonic mesoderm, the third germ layer
- Deuterostome - Biology Simple
In biology, a deuterostome is a type of animal that develops its anus before its mouth This group includes vertebrates, such as humans, and some invertebrates like sea stars and sea urchins This unique developmental characteristic sets them apart from protostomes
- Deuterostomes Definition - BYJUS
“Deuterostome” the word means “second mouth” It is a superphylum of kingdom Animalia grouping together all the animals having bilateral symmetry and the blastopore (the first opening in cleavage) developing into the anus during embryonic development
