Species List: 30-09-2020, Rotunda up river, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

 39 species sighted at Rotunda up river, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 30-09-2020.

A single shore entry dive Gary and David of 269 minutes. Maximum depth 5.2 m, 21 C water temperature, 8+ m viz.

Another early morning spring dive in River awaits, what will we find? I'll tell you - we recorded 39 species and the river remains a magic place. Our strategy was that David would search high and I would search low. It works! Goniodoridella sp. 1 was out in force. This species is so tuff and survives throughout any condition. This species was first recorded by me on the other side of the spit right off shore on the 8th of January 2005 and was a new record for Australia according to Willan. No use ranting about what we found, the list speaks for itself. Epic, sigh...
