Species List: 26-12-2020, Fish Cage up river, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

45 species sighted at Fish Cage up river, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 26-12-2020.

A single shore entry dive with Gary, Fran and Nevar of 220 minutes. Maximum depth 5.3 m, 26 C water temperature, up to 3 m viz.

The tidal flow again was quite low today and with all the silt the water was a bit dirty but we made our way around and recorded some more nice species. Eubranchus sp. 21 is a brand new species and Tenellia sp. 70 is as well with its opaque white rhinophore bases and head with rings on the cerata. 2 large Philinopsis pilsbryi were out on the sand. A large Plocamopherus maculatus was a great find as well. Flabellina lotos continues to be most common. Yet again the river sings!
