Species List: Wobby Rock, Gneering Shoals, Sunshine Coast, 31-03-2015

16 species sighted at Wobby Rock, Gneering Shoals, Sunshine Coast.

Terry and David on this excursion consisting of 1 x 73 minute and 1 x 76 minute dives in water depths of 14m to 19m. 12m viz, 26C water temp and surge.

Wobby Rock is an interesting dive site out near the Blinker on the Gneering Shoals consisting of several large boulders and the crevices created in-between. We were hopeful of cleaner water plus a little more depth to offset the effects of the swell both for our own comfort and reduced effect upon the nudibranch populations. Surface conditions were much lumpier than anticipated given the low wind speed but down below was quite enjoyable. Although the species count is still down a little it was more than compensated for by the finding of some not-so-common species and the addition of a new species to our list - Eubranchus sp. 11.
