27 de abr. de 2017 · Deuterostome Definition. 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.

Deuterostomia (dari bahasa Yunani: "mulut kedua") adalah superfilum hewan. mereka adalah subtakson dari Bilateria cabang subregnum Eumetazoa, dan lawan dari Protostomia. Deuterostomia berbeda karena perkembangan embrionya; pada deuterostomia, lubang pertama dari blastopora menjadi anus, sedangkan pada protostomia lubang itu menjadi mulut .
In deuterostomes, the original dent becomes the anus, while the gut eventually tunnels through the embryo until it reaches the other side, forming an opening that becomes the mouth. [1] It was originally thought that the blastopore of the protostomes formed the mouth, and the anus formed second when the gut tunneled through the embryo.

Protostome. Protostomia ( / ˌproʊtəˈstoʊmi.ə /) is the clade of animals once thought to be characterized by the formation of the organism's mouth before its anus during embryonic development. This nature has since been discovered to be extremely variable among Protostomia's members, although the reverse is typically true of its sister ...
