Deuterostomii se desting prin dezvoltarea embrionară a anusului din blastopor, iar gura se formează secundar (la protostomieni din blastopor se dezvoltă gura). Aceste animale au celom, schelet intern de origine mezodermică și un sistem nervos în ...
Among the bilaterians, they belong to the deuterostome division, meaning that the blastopore, the first opening to form during embryo development, becomes the anus instead of the mouth. [6] [7] The characteristics of adult echinoderms are the possession of a water vascular system with external tube feet and a calcareous endoskeleton consisting of ossicles connected by a mesh of collagen fibres.
