Species List: 23-03-2020, Rotunda upriver Mooloolah River, Mooloolaba, Qld.

7 species sighted at Rotunda upriver Mooloolah River, Mooloolaba, Qld. 23-03-2020.

A single shore entry solo dive by Gary of 125 minutes. Maximum depth 5.4 m, 25 C water temperature and up to 4 m viz.

With all the rain we have had the river was no longer brown, so naturally I decided to see what was on the bottom. Lately a dredger was been working in the river which probably has put about 50 mm of thick silt on the sand and rocks. Goniodoridella sp. 1 continues to be the most common. Because of the layer of silt the numbers of bubble shells was nearly none...found one!
