Species List: 11-08-2017, Elsewhere, Southern side, Old Woman Island, off Mudjimba, Sunshine Coast, Qld.

30 species sighted at Elsewhere, Southern side, Old Woman Island, off Mudjimba, Sunshine Coast, Qld, 11-08-2017

Julie, Terry, Gary and David on this excursion consisting of 1 x 100 minute and 1 x 96 minute dives in water depths from 9 m to 13 m. 15 m viz, 20 C water temp and negligible surge.

The forecast advised of up to 20 knots of wind but indicated it would be blowing out of the NW early and the NE after midday and of lesser strength inshore. This could mean only one thing - Old Woman Island here we come - anchor in the lee and a following sea for the homeward trip. And so it came to pass. We chose a random spot on the southern side not at any of our usual sites hence our naming of Elsewhere. A number of ledges outlining slightly shallower plateaus with sandy gutters in between made for interesting and varied topography to search for sea slugs. Enough species were sighted to keep our cameras busy but nothing of exceptional note was observed. Interestingly, out of the thirty species recorded only one was an aeolid - Cratena simba.
