Species List: 01-09-2016, Nudi Ledge, Currimundi Reef, Sunshine Coast, Queensland.

39 species sighted at Nudi Ledge, Currimundi Reef, Sunshine Coast, Queensland, 01-09-2016

Terry, Gary and David on this excursion consisting of 1 x 90 minute and 1 x 81 minute dives in water depths from 14 m to 17 m. 15 m viz, 20 C water temp and no surge.

With this visit to Nudi Ledge we have completed the recent round of diving the "Nudi" sites. A great range of species were out feeding including some that we only rarely sight. We have decided to separate what until now we have been calling a form of Gonibranchus reticulatus. At this stage we base the distinction, apart from a difference in the mantle surface appearance, mainly upon the particular type of sponge that we always seem to find it feeding upon but which other relatives do not. It will be called Goniobranchus sp. 4 in our list.

Julie, Terry, Gary & David on this single shore entry dive of 127 minutes. Maximum depth 6.9 m, 20 C water temperature and 5 m viz.

An unremarkable dive with just the usual suspects sighted. We have seen specimens of the Flabellina sp. 5 a number of times previously but have been including them with Flabellina angelvaldesi. However we have now decided to separate it until such time as we can confirm.
