Species List: 16-05-2020, Rotunda, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

19 species sighted at Rotunda, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 16-05-2020.

A single shore entry dive by Gary, David, Fran and Nevar of 140 minutes. Maximum depth 5.1 m, 23 C water temperature and up to 3 m viz.

So off we went into the Rotunda. The low tidal flow made for some low vis with other divers finning stirring up the silt....grrrrr. Finding Costasiella sp. 1 was a real treat. The number of species is going up! Unidentia animals continue to bring fire to the river.
