Tentaculata

 

(also Lophophorata or Podaxonia), a phylum of invertebrates. The Tentaculata are predominantly sessile marine animals. They are characterized by bilateral symmetry of the body, a secondary body cavity divided into two or three sections, a U-shaped intestine, and a highly developed tentacular apparatus that directs food particles to the mouth. The phylum comprises three classes: Phoronidea, Bryozoa, and Brachiopoda, which are considered by some taxonomists as independent phyla (seePHORONIDAE; BRYOZOA; and BRACHIOPODA).
