May 2020
Where
seen? This sea hare is indeed rather flamboyant, and is sometimes seen on
our Southern shores, among seagrasses near reefs. Sometimes, half buried in soft sediments. Elsewhere, it is
considered common.
Features: 8-10cm, elsewhere it
can grow to 40cm long! Body large, fleshy and smooth, various shades
of brown with small white spots. The inner surface of the 'wings'
(called parapodia) dark with a pattern of irregular white blotchy
bars and smaller white blotches. Large rhinophores, oral tentacles
with frilly flaps. It releases purple ink when disturbed. It can swim
by flapping its parapodia.
What does it eat? It is believed
to eat seagrass. |
