Phylum brachiopoda
Craniata is a class of brachiopods originating in the Cambrian period and still extant today. [1] It is the only class within the subphylum Craniiformea, one of three major subphyla of brachiopods alongside linguliforms and rhynchonelliforms. Craniata is divided into three orders: the extinct Craniopsida and Trimerellida, and the living ...The lophophore shows extreme variations in different brachiopods. The type present in Magellania is called plectophous type, i.e., a median coiled arm develops between the two simple lateral arms. 3. Body Wall and Masculature of Magellania: The body is covered by a single-layered epidermis on the outerside.
