Species List: 25-01-2026, Trench, Gneering Shoals Nudibranch Day, Mooloolaba, Sunshine Coast, Queensland, Australia.

 34 species sighted at Trench, Gneering Shoals Nudibranch Day, Mooloolaba, Sunshine Coast, Queensland, Australia. 25-01-2025.

A double boat entry dive with Gary and 11 aficionados of two 50 minute dives, maximum depth 19 m, 27 C water temperature, 10-15 m viz.

After some weather events we finally get a fine weather window with a full boat load of Nudibranch interested people. The winds were light, no surface current or surge, less then a metre of swell made for a great day out. 34 species for the team and some we do not see very often, Hypselodoris lacuna Miamira moloch and Myja hyotan were among them.  Chromodoris magnifica, Doriprismatica atromarginata and Thuridilla sp. 6 dominated the substrate today. I am pretty sure everyone was happy!

Time to put time on the test computer and search for some lovelies! Two Goniobranchus variatus were seen today which was great. Murphydoris cobbi continues to be most common today. Three Elysia species were recorded. A half a dozen Goniobranchus daphnae were seen as well. 

I had to end my dive because I was hooked 2 times by 8 Indonesians and I was pissed at their replies!! I have written to Council begging to have fishing banned...
