Species List: 13-10-2017, Coles Hole, Gneering Shoals, off Mooloolaba, Sunshine Coast, Queensland

41 species sighted at Coles Hole, Gneering Shoals, off Mooloolaba, Sunshine Coast, Queensland

Julie, Terry, Gary and David on this excursion consisting of 2 x 61 minute dives in water depths from 16 m to 21 m. 15 m viz, 21 C water temp and no surge.

Although it was a little lumpy on the trip out almost perfect surface conditions (apart from a little surface current) existed by the time we entered the water. We were all in our semi-dry suits and with the water at depth being a little cooler than the shallower dives around the island and in the river we certainly felt its effect. This is a site that has a variety of topography that no doubt usually contributes to the finding of a reasonable number of sea slugs. Finds worthy of a mention include: Goniobranchus sp. 1, Goniobranchus roboi, Favorinus japonicus, Doris sp. 1 and Chromodoris burni. There are two specimens of Dermatobranchus that have us scratching our heads a little. Whilst at first glance they seem similar to species we have recorded previously a closer reading of Dermatobranchus descriptions have us reviewing and rethinking some of our identifications.
