Order Anaspida, Sea Hares

Sea hares have plump bodies with two sets of parapodia on the head.  The mantle is split laterally forming an opening for respiration.  Aplysia feed upon red algae and exude a noxious purple dye when disturbed.  Populations are dynamic, abundant some years, absent others.  They are hermaphroditic and may form mating chains containing many individuals.
