Description
Stiliger is a genus of small sacoglossans (sap-sucking sea slugs) in the family Limapontiidae; they resemble nudibranchs but are not closely related to them. The type species S. ornatus was described from the Red Sea and also occurs in Mozambique, Japan and the Great Barrier Reef, living on the green alga Codium. It is about 10 mm long, and some Stiliger species look green because of the algae they eat.
Identification
S. ornatus is a tiny sacoglossan with a yellow body and a blue-green stripe along the back, indigo-banded dorsal papillae with yellow tips, and club-shaped rhinophores coloured yellow and blue. The sources describe the genus mainly through single species, so genus-level identification is weak.
