Julie, Terry, Gary & David on this single shore entry dive of 94 minutes. Maximum depth 6 m, 23 C water temperature and 3 m viz.

The sponges must be catching up with the hydroids in the river as we are starting to see more species of sponge eating dorids. A nice find was the new species: Trinchesia sp. 38 that at first glance bears some similarities to Trinchesia yamasui. The water temperature is on the way up - yippee.

Species List: 19-10-2016, Shellacey Reef, Gneering Shoals, Mooloolaba, Queensland

39 species sighted at Shellacey Reef, Gneering Shoals, Mooloolaba, Queensland, 19-10-2016

Terry, Gary, David Hill and David on this excursion consisting of 1 x 71 minute and 1 x 70 minute dives in water depths from 14 m to 17.7 m. 8 m viz, 21 C water temp and some surge but less so down in the deeper gutters..

We departed Mooloolaba Harbour on More Mischief deciding to head a little further offshore hoping to obtain better visibility than we had been experiencing of late. There were whales aplenty but also a sea surface covered with an algal bloom due to the calm conditions. There were a couple of species that we haven't sighted in quite awhile including Ardeadoris carlsoni, Ardeadoris sp. 1 & Chromodoris magnifica.
