Species in this phylum with thin laminae are termed illoricate, and members of this phylum exhibit 9 different morphologies of trophi, small jaws that line the pharynx. Parthenogenesis and the ability to survive desiccation through cryptobiosis characterize class Bdelloidea [dell-OY-dia]. The namesake feature of these pseudocoelomates [soo-doh-SEE-lum-ates] is used for propulsion and for sending food past the trophi by generating a vortex of water. FTP, name this invertebrate phylum characterized by a corona of cilia whose beating led Leeuwenhoek to call them "wheel animalcules."
