Species List: 23-01-2018, Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

9 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 23-01-2018.

A single shore entry dive by Gary and David of 137 minutes. Maximum depth 6.4 m, 28 C water temperature and 4 m viz.

Over two hours of searching only produced 9 species. The juvenile Thuridilla carlsoni had us excited for awhile until we reviewed our pics. We were pleased to find a Facelina sp. 11 cruising the silty substrate as usual. This behaviour leads us to conjecture that it perhaps hunts anemones or individual hydroids out on the sand.
