The sea hare has flaps of tissue on its back, thought to look like the ears of a hare. Herbivorous, the type of seaweed they eat may affect their colour - either red, brown or green. The above specimens have thus probably been eating red seaweeds. Like all sea slugs, the sea hare is a hermaphrodite. Unusually, though, any sea hare can fertilise any other. Several sea hares can form a mating chanin where each behaves as a male to the one below it, and a female to the one above.
