California Sea Hare

Description:

From Wikipedia: 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. Like all sea hares, the California sea hare is hermaphroditic, acting as male and female simultaneously during mating. The eggs are yellow, but after 8 to 9 days change into a brown color before hatching into larvae. When this annual animal is laying eggs, it has reached the end of its life. Its lifetime depends somewhat on the temperature of the water: 14-25 degrees Celsius is best, but a cooler temperature delays spawning and extends its life somewhat. When it is considerably disturbed the sea hare is capable of releasing reddish-purple ink (much like an octopus does) from a gland in its mantle cavity.
