Species List: 03-01-2020, Rotunda, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

24 species sighted at Rotunda, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld. 03-01-2020.

A single shore entry dive by Gary, Fran and Nevar of 177 minutes. Maximum depth 5.1 m, 28 C water temperature and up to 4 m viz.

More of summer is here, this dive had 28C water temp, nice! Found from under a rock were some some small white circular egg masses ok there must be a nudibranch, and sure enough Okenia sp. 10 a real beauty. Another great find was Plakobranchus ocellatus after a long drought. The river, in this section, is covered in silt which is probably the reason the numbers were down. Also a large Pleurobranchus weberi was found a first for Fran and Nevar.
