Species List: 11-06-2020, Rotunda, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

23 species sighted at Rotunda, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 11-06-2020.

A single solo shore entry dive by Gary of 250 minutes. Maximum depth 5.4 m, 21 C water temperature up to 10 m viz.

Another beautiful morning to go dive the river. The vis is still nice at up to 10 m, the current was near nil. Some very interesting species were recorded. I always love to Costasiella kuroshimae with it's funny slide. Finding Facelina sp. 4 x2 was great since I haven't seen this one in a while. Goniodoridella sp. 1 is still the most common in the river as are Unidentia species, Cratena lineata and Flabellina lotos. A Rostanga arbutus was found in a shallow hole on its orange sponge.
