Where
seen?
This large nudibranch is sometimes seen near living reefs on some
of our Southern shores. It may be seasonal: when seen, often many
individuals are spotted during the same trip.
Features: 10-12cm long. Flat stiff
body white, finely granular surface with lots of tiny brown raised
pimples. There are orange edges of the body and foot, and the openings
where the large rhinophores and feathery gills emerge. The underside
is plain white with a narrow foot and small oral tentacles. It can
drop off portions of its body mantle when alarmed. So don't handle
it.
What does it eat? It probably
eats sponges. |
