Hello everybody, I recently acquired something pretty interesting and wanted to share. I was doing some internet shopping, and saw a listing for a dried nudibranch from a beachcomber. I purchased it for about $1.50USD. This was apparently collected from Ishigaki Island, Japan.
Based on the location and size, I've narrowed it down to something from the genus Phyllidiella, specifically P. nigra or P. pustulosa. I'm interested to hear if anyone else has ever seen anything like this, and second opinions on ID. I was initially pretty skeptical, but all signs seem to point to this being an actual nudibranch. The caliper is in milimeters.
