33 species sighted at Rotunda upriver, La Balsa Park, Mooloolah River, Sunshine Coast, Qld. 01-10-2021.

A single solo shore entry dive with Gary of 241 minutes. Maximum depth 5.3 m, 21-22 C water temperature, up to 5 m viz.

End of week getting in before it gets worse diving! So off I went equipped with my 7 mm wetsuit. What I saw were a lot of nudibranchs! In fact 33 species. Not bad for a cruise on the bottom. Upon resting on the bottom I readied myself for the hunt. After that I turned and there was Diversidoris aurantionodulosa, great! Recording another Embletonia gracilis was great, have not seen one in a while. Another epic outing in this magnificent diverse river.
