Species List: 12-06-2018, Clown Reef, Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld.

25 species sighted at Clown Reef, Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld, 12-06-2018.

Nick, David, Gary and David on this excursion consisting of 1 x 66 minute and 1 x 71 minute dives in water depths from 14 m to 18 m. 25 m viz, 22 C water temp and moderate surge.

Great surface and underwater conditions were enjoyed again except for the surge that made photography of the smaller species somewhat difficult. Finds of note include: Diversidoris flava, Goniobranchus kuniei, Mexichromis macropus, Tambja morosa and Verconia decussata. Compare the photo of Verconia decussata with that of Verconia simplex and observe the differences between their rhinophores and gills. We had the pleasure of an unexpected visitor in the form of a Northern Giant Petrel that showed no fear by swimming right up to the swim platform to check us out.
