Opisthobranch of the Week Data
Crimora lutea is considered to be very rare on Okinawa as I have seen and collected only a single individual over a period of more than twenty years of diving here. The animal was found and collected during a daytime SCUBA dive in seven feet of water; it was crawling in the open on coral rubble.
Including Crimora lutea, I currently have nine genera and 18 described species of polycerids from here on the main island of Okinawa. In terms of field identifications of Okinawan material, C. lutea is the only polycerid found here having a yellow body with small black papillae irregularly scattered over the notum and tail. See Polycera abei for a similar appearing polycerid found in the Kerama Islands group.
Kikutaro Baba (1949) described the species based on two specimens which were collected from Sagami Bay, Japan in 15m and 17m of water.
