Roboastra gracilis from Malaysia

September 11, 2003
From: Asther M. Lau


Hi again...
Found this one crawling away from another of same kind. It was crawling on the bottom of sand and rocks. No eggs were found so don't think they mated. There is a small opening on its right side near the rhinophore.

Site: Labas Is. Tioman, Malaysia
Depth: 15 meter
Date: 10th August 2003
Size: About 2.5 cm on crawling position

Please help identify.
Thank you!

Dear Asther,
This is Roboastra gracilis. The orange marks can range from rows of spots to lines, but it is always recognisable by the proportionally large bluish gills and rhinophores
Best wishes
