Species List: 06-12-2019, Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

46 species sighted at Rotunda upriver, La Balsa Park, Mooloolah River, Sunshine Coast, Queensland, Australia, 06-12-2019.

A single shore entry dive by Gary, Fran, Never, Harvey and David of 243 minutes. Maximum depth 5.7 m, 26 C water temperature and up to 9 m viz.

A 34C summer day and sunny, not many people at the park and plenty of parking must mean a great dive coming up. Between the five of us you would think we would find everything. The water clarity was also great. The current was ever-so-slight. Our latest species Phyllodesmium sp. 8 was found from under a rock, a stunner, one I have not seen before, And then there were way more than one Phyllodesmium undulatum...striking! Finding Limacia ornata and Onchidoris maugeansis were real treats, they make you work at finding them. Finding Philinopsis sp. 5 with it's golden margin was a surprise.
