      Mollusks

      (Science: zoology) One of the grand divisions of the animal kingdom, including the classes Cephalopoda, Gastropoda, PteropodaScaphopoda, and 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.

      Formerly the Brachiopoda, Bryzoa, and Tunicata were united with the Lamellibranchiata in an artificial group called Acephala, which was also included under Mollusca. See Molluscoudea.

      See our dictionary also for arthropods. I didn’t know medical examinations tested phylums…

      Hm, this sounds interesting. Could you tell me the relationship between your pre medical examination and the Molluscs and Arthropods things? I am starting to do a research in Immunobiology using mollusc species. Maybe we can do something together or whatever… 😉
