Placida cremoniana (Trinchese, 1892)
1-2mm Qajjenza <1m depth 23/8/93
Small sacoglossan found in shallow water on algae. The base body colour is a transparent white but an intense orange-brown pigment is present on the dorsum with purplish blotches near the head. The cerata are numerous, almost skittle-shaped, with an intense orange brown colour at the base and a dark purple colour is present up to the tips. Rhinophores are present as two short folded tentacles with a wide transparent band at the edge.
Size range of specimens: 1-4mm. Rare.

Specific characteristics: An unmistakable species which is distinct from all other sacoglossans, the colour and folded tentacles are the key distinguishing features.
