Opisthobranch of the Week Data
Initially the above animal was listed here as Subcuthona pallida (20 March, 2006), but recent information has come to my attention from Erwin Koehler (pers. comm. to Erwin from Richard Willan) that it is in fact a Phyllodesmium species. Phyllodesmium sp. 3 is considered to be very rare in the waters of Okinawa's main island as I've seen and collected only the above single featured animal. The animal was collected from seventy-five feet in an area of mixed sand and coral rubble near the reef forefront. It was initially found embedded in a slab of coral rubble and as the animal was tightly attached to the rubble, the slab of rubble containing the aeolid was cut off with a knife and placed into a zip-loc bag. Later at home the animal had crawled from the rubble and it was subsequently noted that the foot would very tightly adhere to any substrate it was placed upon.
Furthermore, I've added a second page with three additional images of the above animal.
The above featured animal is one of several undescribed species of Phyllodesmium species known from Okinawan waters; previously I've featured on these pages the following described and undescribed (or at least unknown by myself) Phyllodesmium species:
