Furry
sea hare
Stylocheilus sp.
Family Aplysiidae
updated
May 2020
Where
seen? This is another 'hairy' sea hare sometimes seen on
some Southern shores. Usually large numbers are seen during a visit and then
none for a very long time.
Features: 5-8cm, sometimes much smaller. Body long
with a long 'tail'. It is covered in tiny spiky 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. It comes in various shades of
brow, usually with bright blue or purple spots which are ringed in
black or brown. With many fine lines in parallel stripes. Usually
well camouflaged and blends in perfectly with among seaweeds and seagrasses.
Sometimes mistaken for the Hairy
sea hare which have flat thicker 'hair' and lack fine parallel lines. 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. |
