Species List: 19-09-2017, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld

13 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 19-09-2017.

A single shore entry dive by Gary, Elliot and two friends of 119 minutes. Maximum depth 6.4 m, 21 C water temperature and up to 8 m viz.

The poor showing of the once common Flabellina rubrolineata and Tenellia sibogae is evident of a food source that is disappearing. The little Goniodoridella sp. 1 is still the common nudibranch. The first part of the dive tested us in a ripping current but it sibsided and the count began to rise.
