Species List: La Balsa Park, Mooloolah River, Sunshine Coast, 24-04-2016

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

Julie, Gary and David on this single, shore entry dive of  151 minutes. Maximum depth 6.2 m,  23 C water temperature and 5 m viz. (Terry's regulators developed a last minute problem so he sat out the dive.)

Not as many species sighted however two new to our list were found. The Thordisa villosa was concealed just below the surface of the sand, its presence betrayed by a circle of slightly different colouration. The undescribed Elysia is one we have seen here before but failed until now to recognise it as a distinct species.
