SpeciesList: 29-04-2017, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld

11 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 29-04-2017.

A single shore entry dive by Julie, Terry, Gary and David of 104 minutes. Maximum depth 6.0 m, 23 C water temperature and up to 1 m viz.

There was a lot of particulate matter in the water that reduced the visibility considerably but did not affect the enjoyment of the dive. We all stayed in touch and moved slowly over the substrate examining it closely. Seven of the eleven species sighted were aeolids that were feeding on the hydroid coverage. The sighting of Facelina sp. 11 is only the second time we have seen it.

Species List: 25-04-2017, Coles Hole, Outer Gneerings, off Mooloolaba, Sunshine Coast, Qld

39 species sighted at Coles Hole, Outer Gneerings, off Mooloolaba, Sunshine Coast, Qld, 25-04-2017.

Julie, Terry, Gary and David on this excursion consisting of 1 x 70 minute and 1 x 71 minute dives in water depths from 16 m to 20 m. 15 m viz, 24 C water temp and a little surge.

Conditions were much improved compared to our excursion out to the Gneerings last week. Very pleasant dives on interesting terrain and a good cross section of sea slugs were sighted. A little deeper in parts than our usual profile. The outstanding find of the trip was Euselenops luniceps and not so much as a species but rather by the way it was sighted. On the ascent after the first dive it was observed to be swimming in the water column at 10 metres depth. Doris sp. 1 is only sighted rarely and the Phyllidiopsis xishaensis only once before by us. We follow Yonow, 2002 in giving it this name.
