Very small sized sacoglossan found in shallow water
on the green alga Halimeda tuna on which it is very
well camouflaged. The body colour is a mottled green
with white spots at the edges and two purple rings on
the rhinophores. The flattened body is rounded but
becomes elongated as the animal moves. Rhinophores
are present as a short inrolled pair. Parapodia are
absent. An unusual specimen with a yellow, orange,
green and blue pattern on the dorsum has been
described by Perrone in 1980 (Boll. Malacologico,
16(3-4):103-104) from an unusual specimen
collected in Malta (1979, leg. David Attard)
Size range of specimens: 2-5mm.
Specific characteristics:A common species which is
easily distinguished from other opisthobranchs by its
shape, colour and habitat.
