Species List: 05-12-2019, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

32 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Sunshine Coast, Queensland, Australia, 05-12-2019.

A single shore entry dive by Gary and Brenton of 195 minutes. Maximum depth 5.9 m, 25 C water temperature and up to 8 m viz.

Yet again a 32C temperature day, nice to get wet for a while. On the surface the water looked really blue. The vis was up to 8m and quite nice. In the beginning of the dive found from under a small rock was out latest species Okenia sp. 9. The unique Okenia body was not recognised as one we have seen before (heart rate just went up!). Goniobranchus geometricus were out in force feeding on the dark coloured sponge. Finding a slime of three was a treat. Also found was a mating pair of Thuridilla carlsoni, first time I have seen this.
