Species List: La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, 20-09-2014

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

Julie, Terry & David on this single shore-entry night dive of 99 minutes in water depths to 6m. 6m viz and 20C water temp.

The weather finally put paid to our good run of reef diving but we are fortunate in being able to fall back on the river until the wet season is upon us again. This time we decided to use the centre set of stairs out of the park into the river. Although we only probably moved about 30m along the shoreline during the dive our finds were nothing short of remarkable. Four species new to our list were found contributing to the nine that we had not seen here in the river before. This site continues to amaze us and probably the most amazing sight was the huge Sebadoris fragilis that was as long and as wide as my whole gloved hand and fingers. Incredible to watch move over the bottom.

Species List: Dakota, Currimundi Reef, Caloundra, Sunshine Coast, 19-09-2014

37 species sighted at Dakota, Currimundi Reef, Caloundra, Sunshine Coast.

Terry and David on this excursion consisting of 1 x 94 minute and 1 x 82 minute dives in water depths of 13m to 15m. 15m viz, 20C water temp, no surge.

This is a new site for us on Currimundi Reef picked up on the sounder that morning. The underwater terrain reminded Terry of the rolling hills of Dakota (don't know if that is first-hand experience or just a wasted youth watching too many cowboy and indian movies) being a series of gentle folds in the reef with scattered rocks and old coral plates lying in the shallow gutters providing shelter for the more reclusive species. The Goniodoris sp. 3 is a new species to our list. It possesses a very fine edged mantle that is cupped up in an hour glass shape around the rhinophores and gills. Found deep in algal turf.
