Description The California sea hare also known as the California sea slug, scientific name Aplysia californica, is a species of sea slug, specifically a sea hare, a marine opisthobranch gastropod mollusk in the sea hare family, Aplysiidae.
The California sea hare can be very large - the maximum recorded length is seventy-five cm (thirty inches) when crawling and thus fully extended, although most adult specimens are half this size or smaller.
A closely related species, Aplysia vaccaria, the black sea hare, can grow to be larger still.
Habitat Ocean or bay shallows.
