Species List: 19-07-2018, The Caves & Coles Hole, Gneering Shoals, Mooloolaba, Sunshine Coast, Qld

14 species sighted at The Caves and Coles Hole, Gneering Shoals, Mooloolaba, Sunshine Coast, Qld, 19-07-2018.

Julie and Terry on this excursion consisting of 1 x 44 minute and 1 x 58 minute dive in water depths up to 19 m, 20 m viz, 20 C water temp and no surge.

The weather forecast was ideal for Julie and Terry to assist Reef Check Australia to confirm the location of one of the survey sites. Julie and Jodi dived The Caves, confirming the survey site location, but Julie could not resist the urge to photograph the nudibranchs. We then headed out to Coles Hole where Terry joined us for a leisure dive. It was nice to find the Doriprismatica dendrobranchia, only the 2nd time sighted in 15 years.
