learn only 3 things about them ...
hares may secrete a purple dye. But don't tease them to
make them do this.
they can be quite large, they are well camouflaged. Watch
Sea hares have very specialised diets and should not be
kept in home aquariums.
This hirsute sea hare is sometimes seen on our Northern shores among
seagrasses and seaweeds. Sometimes many are seen everywhere, then
they are no longer seen for many months. Sometimes, they are seen
gathered together, densely packed in large numbers, possibly mating?
Or simply gathering around a good source of food?
Features: 6-12cm. Body long, fleshy
with a short triangular tail which has white bars. It is covered with
lots of flat branching finger-like projections. It has two pairs of
tentacles, oral tentacles and rhinophores about the same size (you
have to look carefully among the hairy bits to distinguish the tentacles).
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 may come in
different shades of brown, sometimes bluish, sometimes with orangey
'hairs', usually with bright blue spots which are ringed in brown.
It is usually well camouflaged and blends in perfectly with among
seaweeds and seagrasses. Like some other sea hares, it produces a
purple ink when disturbed.
Sometimes mistaken for the Furry
sea hare (Stylocheilus sp.). More on how
to tell apart hairy slugs and snails.
What does it eat? It eats cyanobacteria,
in particular, the mat-forming Lyngbya majuscula, which was
formerly known as the filamentous blue-green alga Microcoleus lyngbyaceus.
Apparently, Bursatella sea hares swallow large amounts of sand
in the process of eating, somewhat like earthworms do.
