sea hare

sea hare
any gastropod of the order Aplysiacea, comprising large marine sluglike mollusks with a reduced, internal shell.
[1585-95]

* * *

 any marine gastropod of the family Aplysiidae (subclass Opisthobranchia, phylum Mollusca) that is characterized by a shell reduced to a flat plate, prominent tentacles (resembling rabbit ears), and a smooth or warty body. Sea hares eat large seaweeds, and all are simultaneous hermaphrodites. An example is the 10-centimetre (4-inch) spotted sea hare (Aplysia dactylomela), a ring-spotted green species living in grassy shallows of the Caribbean. Research involving sea hares has greatly increased the scientific understanding of the biochemical basis of learning.
