  Sea hare - Wikipedia, the free encyclopedia
Sea hares (a type of sea slug) are small marine gastropod molluscs of the suborder Anaspidea (P. Fisher, 1883) in the subclass Orthogastropoda, class Gastropoda, phylum Mollusca.
Sea hares are herbivorous and are typically found on seaweed in shallow water.
Aplysia californica is a typical example of a sea hare, and is noteworthy for its usefulness in studies of neurobiology.

I was pleased to see that the two species of sea slugs in the aquarium happened to be 2 of the more likely sea slugs (sea hares and lettuce sea slugs) to survive in captivity, and there were none of the more colorful and infinitely more difficult nudibranchs that are so often imported.
Sea slug, on the other hand, is a descriptive term that can be applied to any of the shell-less gastropods that live in the sea.
These sea hares are of interest to aquarists, because they are among the few species that tend to feed on these highly distasteful nuisance algae that are avoided by the majority of the animals in our aquaria.

The proteins of the ink seem to be synthesized by the sea hare itself and are not obtained directly from the diet, as is the case for the ink pigments.
Feeding habits of sea hare were examined monthly during daytime at low tide by observing the seaweed species consumed in the field and by dissecting under a stereomicroscope the gut contents of the sea hares and capturing the images with a digital camera (Sony-Mavica, Japan).
At the end of this period, sea hares were anaesthetized by storage in a refrigerator and then dissected carefully to remove the ink gland.
