Species List: Bornella Reef, SE corner of Old Woman Island, Sunshine Coast, Queensland, 27-03-2015

18 species sighted at Bornella Reef, SE corner of Old Woman Island, Sunshine Coast.

Terry and David on this excursion consisting of 1 x 94 minute and 1 x 85 minute dives in water depths of 12m to 14m. 3m viz, 25C water temp, some surge.

Once again conditions were not the best which has been the story of our diving this summer. Regardless of conditions however we still enjoy the diving and wondering what we might find during our time below the surface. The recent and consistently large swells whilst welcomed by the surfing fraternity washes many of the sea slugs off their food and the visible substrate down into the clefts and crevices away from our prying eyes. There is a bubble shell - cephalaspidean - listed here as a Tornatina. We have recently been advised by Bob Burn that the name we had been using - Acteocina - applies to Atlantic species only whilst our finds here are of the Tornatina genus. Our website species list has been amended.

Species List: NW Reef, Old Woman Island, Sunshine Coast, 23-03-2015

8 species sighted at NW Reef, Old Woman Island, Sunshine Coast.

Terry and David on this single dive of 55 minutes, 10 m depth, 26C water temp, less than 5 m viz, and surge.

Poor visibility, surge and the boat dragging its anchor in the swells caused us to cut the first dive short and to pass on undertaking the second. The species count reflects the conditions as does the quality of the images.

The Eubranchus sp. 8 has only been sighted twice before at Flinders Reef three years ago on both occasions.

Species List: Shellacey Reef, Gneerings Shoals, Sunshine Coast, 22-03-2015

29 species sighted at Shellacey Reef, Gneering Shoals, Sunshine Coast.

Terry and David on this excursion consisting of 1 x 90 minute and 1 x 85 minute dives in water depths of 14m to 18m. 8m viz, 26C water temp, some surge.

Summer diving conditions have not been kind to us this year with almost a 2 month hiatus from offshore diving excursions. Mischief is now back in service out of Mooloolaba and so we took advantage of the promising forecasts to head out to the Gneering Shoals to see what we could find. The wind strength and direction was not as predicted but we managed two excellent dives before heading back. One specimen has us somewhat confused being similar in some respects to both Goniobranchus aureopurpureus and Thorunna perplexa. Identity TBA.
