The Burnt Placida (Placida cremoniana) is a small opisthobranch species that is a member of the sacoglossid group. The common name for this species was obtained from Neville Coleman’s “Guide to 1001 Nudibranchs” and has previously been referred to as Stiliger cremoniana. This species is known to occur in the waters of the Indo-Western Pacific and in the Mediterranean Sea. It has been recorded in the waters of Japan, Kerama Islands, Okinawa, Sulawesi, Indonesia, Baja – California, Mexico and New South Wales in Australia. It was originally described from a specimen found in the Mediterranean Sea near Naples. Similar to other sacoglossids, this species feeds on tangled mats of filamentous green algae.
The Burnt Placida (Placida cremoniana) grows to a maximum length of approximately 7mm.
