Species List: La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, 16-07-2015

6 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast.

Julie and David on this single shore entry dive of 95 minutes, with Terry offering surface support. Maximum depth 6 m, 17 C water temperature and 5m viz.

This dive was commenced at the most eastern end of La Balsa Park at the last set of stairs towards the river mouth. Our finds noted here are double the number of species found over a month ago so things are undoubtedly on the improve following the exterminating flush-out caused by Cyclone Marcia. Two things of note are worth mentioning: The aeolid Unidentia angelvaldesi is always in very low numbers or missing entirely along this particular stretch and the Gymnodoris sighted, although not for the first time, is not Gymnodoris alba. We have it mixed up with that species on this web site. It is a different species and we believe it is time to separate it and have designated it here as Gymnodoris sp. 10 - a new species. Still waiting on the long anticipated review of the gymnodorids.
