Elysia trisinuata Baba, 1949

Maximum size: 20 mm.
Identification:
This
species
is dark olive with scattered white flecks. The parapodia have three low
chimneys frosted with white and the rhinophores are tipped in brick
red. The body surface is covered with small papillae giving it a
felt-like appearance and the inner surfaces of the parapodia have many
elevated veins.
Natural history:
During
sorting, a single Elysia
trisinuata
was found in a sample of Codium
sp. collected from shallow
water, probably at less than 1 m (3 ft). It almost perfectly mimics the
appearance of its host algae and
is known to feed on Codium
elsewhere in the Pacific (Sea Slug Forum).
Distribution:
French Frigate Shoals: also known from southern Japan and Hong Kong.
Taxonomic notes:
First
recorded in Hawaii by the 2006 CREEF expedition on Oct. 22, 2006.
The name means "having three bends."
