Species List: Drop Off, Currimundi Reef, Sunshine Coast, 26-07-2015

34 species sighted at Drop Off, Currimundi Reef, Sunshine Coast.

Julie, Terry and David on this excursion consisting of 1 x 92 minute and 1 x 77 minute dives in water depths of 14m to 17m. 8m viz, 20C water temp, very little surge.

Terry had expressed a desire to return to this site for a better survey. With the nasty swell of Friday having abated we ventured forth over the Caloundra Bar without incident and headed north up to Currimundi Reef. What a complete change in underwater conditions greeted us. The lack of surge made the dives much more comfortable and gave us a marked increase in the species count and their populations. The only disappointment was the lack of sacoglossans of any description. Not a single Thuridilla or Elysia in sight which we are unable to explain given the good coverage of many types of algae upon the substrate.
