Species List: 26-03-2017, Terry's Delight, Arkwright Shoals, south of Coolum, Sunshine Coast, Queensland

29 species sighted at Terry's Delight, Arkwright Shoals, south of Coolum, Sunshine Coast, Qld, 26-03-2017.

Julie, Terry, Gary and David on this excursion consisting of 1 x 79 minute and 1 x 76 minute dives in water depths from 13 m to 17 m. 6 m viz, 27 C water temp and considerable surge.

The weather forecast proved accurate in all respects apart from the predicted swell the size of which caught us by surprise making photography quite difficult. As previously experienced the swell has a definite effect upon the species count by way of both our ability to find slugs and the slugs own penchant for finding the nearest crevice in which to escape the constant to and fro. (We were seriously considering renaming this site "To & Fro".) However all was not lost as we found a specimen of a rarely seen slug - Miamira moloch and what a beauty it is too. We have found this species in several forms of external appearance over the years and the existence of these variations begs the question - is there more than one species amongst them all?
