Species List: 17-08-2020, Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

29 species sighted at Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 17-08-2020.

A single shore entry dive Gary, David, and Tracey of 220 minutes. Maximum depth 5.0 m, 20 C water temperature up to 8 m viz.

A night dive was in order so we met at 2.0 am geared up and was at the bottom at about 3.30 am. The bum of the outing was when Harvey's zip broke and he could not join us. The water pretty clean. Again the river gives up some interesting species. The highlight for me was recording a 60 mm pre-adult Pleurobranchus weberi! Beautiful. Night tends to bring out the Pleurobranchus species! Another great adventure in the greatest river in the World! What's next?
