Aplysia parvula
Family Aplysiidae

Where
seen?
Seen once on Sisters Island, among Hairy
green seaweed (Bryopsis sp.) near living reefs.
Features: About 5cm. A long thin
body with a pair of small 'wings' in the middle and long oral tentacles
and rhinophores. The hole between the wings (called the foramen) is
large in this sea hare and is usually ringed in black. In other sea
hares, the foramen is microscopic. They come in a wide variety of
body colours but usually the 'wings' have a black edge and the tips
of the rhinophores and oral tentacles are dark.
It is among the smallest of the Aplysia sea hares, and 'parvus'
means 'little'. (It isn't the smallest sea hare: the seagrass
seahare (Phyllaplysia sp.) is much smaller).
Sometimes mistaken for the Leaf
slug (Elysia ornata) which is not a sea hare but a sap
sucking slug. The Leaf slug only has one pair of tentacles and its
'wings' are much longer, extending along most of the body length. |
