Rotifer mastax
WebRotifer predators or raptors are defined in several ways: species without any buccal tube and whose mouth opening leads directly to the mastax ; rotifers showing a grasping action and having access to larger food particles ; rotifers actively grasping food (also known as macrofilter feeders) and Asplanchna ; large-bodied rotifers that consume ... WebDigestive System of Rotifers: The mouth usually lies in the buccal field. Sphincter and dilator muscles may open and close it. Mouth leads, by a ciliated buccal tube, into the pharynx. The pharynx or mastax is a unique rotifer structure. It is a muscular chamber containing hard chitinous jaws called trophi. Jaw structure is complex.
