Species List: 01-07-2018, Hanging Rock, Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld.

19 species sighted at Hanging Rock, Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld, 01-07-2018.

Gary and David on this excursion consisting of 1 x 83 minute and 1 x 74 minute dives in water depths from 12 m to 15 m. 15 m viz, 20 C water temp and moderate surge.

It’s been some time since we examined the middle portion of the Gneering Shoals so we selected a site we frequently dived in the past called Hanging Rock for this excursion. Sea slug species seemed few and far between and it took a great effort to locate the 19 species we did see. There is also a gutter at this site that we always examined but failed to locate it on this trip much to our disappointment. The Berthellina citrina specimens were all located together under a small plate of dead coral. Finds worth special mention include: Verconia verconiforma, Hypselodoris sagamiensis, Kabeiro sp. 1, Ceratosoma tenue and Dendrodoris nigra.
