Species List: La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, 30-08-2015

16 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast.

Julie, Terry and David on this single shore entry dive of 123 minutes. Maximum depth 6 m, 20 C water temperature and 4 m viz.

The river is starting to produce good numbers of sea slugs once again although this is in stark contrast to the previous dive in the river - not recorded in the Blogs - a night dive on 27/08/2015 at the far eastern end of the park when the total count only consisted of two specimens of Unidentia angelvaldesi. The interesting point is that there are two species in the list below that we have not encountered previously in the river. The Gymnodoris nigricolor was a much larger specimen than the one found here for the first time a week and a half ago.
