Julie, Terry, Gary and David on this excursion consisting of 1 x 93 minute and 1 x 81 minute dives in water depths from 9 m to 14 m. 10 m viz, 26 C water temp and surge.
Species count was a little down due no doubt to the surge experienced on this shallower portion of the shoals. This is only our second visit to this site, the first being back in November 2013. It is slightly to the north of Terry's Delight and differs in substrate topography with large jumbled boulders falling away into sand. Large numbers of Tylodina corticalis were present. Of particular interest were the two specimens of Goniobranchus geometricus with a startling difference in the notum appearance.
