Definitions for Mollusca:

The Collaborative International Dictionary of English v.0.48 :
Mollusca \Mol*lus"ca\, prop. n. pl. [NL. See Mollusk.] (Zool.) One of the grand divisions of the animal kingdom, a phylum including the classes Cephalopoda, Gastropoda, Pteropoda, Scaphopoda, and Pelecyopoda (syn. Bivalvia, formerly called Lamellibranchiata, or Conchifera). These animals have an unsegmented bilateral body, with most of the organs and parts paired, but not repeated longitudinally. Most of them develop a mantle, which incloses either a branchial or a pulmonary cavity. They are generally more or less covered and protected by a calcareous shell, which may be univalve, bivalve, or multivalve. [1913 Webster +PJC] Note: Formerly the Brachiopoda, Bryzoa, and Tunicata were united with the Lamellibranchiata in an artificial group called Acephala, which was also included under Mollusca. See Molluscoidea. [1913 Webster]

WordNet (r) 2.0 :
