Furry
sea hare
Stylocheilus sp.
Family Aplysiidae
updated
Aug 10
Where
seen? This is another 'hairy' sea hare sometimes seen on
some shores. Usually large numbers are seen during a visit and then
none for a very long time.
Features: 5-8cm.
Body long
with a long 'tail', with blue spots, fine lines and tiny projections
that give it a furry look. The
oral tentacles and rhinophores are about the same size. The oral tentacles
usually lack large 'hairy' projections and has no flaps. The parapodia
appears to be a hole in the centre of the body, rather than 'wings'
or flaps as in other large sea hares. Usually well camouflaged and
blends in perfectly with among seaweeds and seagrasses.
Sometimes mistaken for the Hairy
sea hare (Bursatella leachii). Both are hairy, but the
long-tailed hairy sea hare has fine lines along the length of the
body and its oral tentacles and rhinophores are more easily distinguished.
Some 'hairy' snails also look like the hairy sea hare. More on how
to tell apart hairy slugs and snails.
What
does it eat? It
feeds on cyanobacteria
formerly known as the filamentous blue-green algae. These sea hares
are preyed upon by the Gymnodoris
nudibranch. |
