2017年4月27日 · 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.

Deuterostome - Biology Simple
2024年3月7日 · 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.
Deuterostome - Classification, Superphylum, Characteristic and …
Deuterostomia are mainly a group of animals (Kingdom: Animalia) that are characterized by their process of anus formation. In this group of animals, the development of the anus starts before the formation of their mouth during embryonic development.

Deuterostomes: Definition, Characteristics & Classification - ALLEN
In Deuterostomia, a significant group of metazoans, embryonic development is characterized by the formation of the anal opening from the blastopore, marking the posterior end of the body. Subsequently, the mouth forms later in development.
