Opisthobranch of the Week Data
Taxonomy:
Tritoniopsilla alba is considered to be uncommon on Okinawa as I have seen and collected a total of 11 individuals, as of 27 December, 1985. In addition to the eleven collected individuals, nine others were photographed, but not collected. Numerous additional individuals have been seen but neither photographed nor collected. My records indicate both collected and photo-only specimens came from two sites (Horseshoe Cliffs, and Seragaki); individuals from additional locations were probably(?) seen, but the data was not recorded.
Like other members of the genus, T. alba feeds on octocorals. This investigator, at one time, found 7-8 individuals on a single small alcyonacean octocoral in three feet of water.
