Species List: 18-02-2020, Toilet Block upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

9 species sighted at Toilet Block upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld. 18-02-2020.

A shore entry dive by Gary and Steve of 131 minutes. Maximum depth 5.6 m, 28 C water temperature and up to 2 m viz.

The river is at the end of its Nudibranch LIFE. So much has been killed off and very few nudibranchs. Many Bubble shells were recorded maybe because of the salinity of the water. The highlight for me was recording a second Ringicula sp. shell.
