Species List: Nudi Plateau on Currimundi Reef, Sunshine Coast, 02-05-2016

43 species sighted at Nudi Plateau on Currimundi Reef, Sunshine Coast.

Terry, Gary & David on this excursion consisting of 1 x 79 minute and 1 x 83 minute dives in water depths from 13.5 m to 16.5 m. 15 m viz, 24 C water temp and some surge.

Nudi Plateau is a new site for us consisting of a large plateau with shallow fissures and depressions, a low wall where it drops into the sand and areas of individual and jumbled boulders off to one side. On our way to Nudi Ledge we peeled off looking for varying depths on the sounder and this spot looked promising and so it was. As well as a high species count we added yet another new one to our list - Trinchesia sp. 36 - with beautiful lemon-yellow bands on the cerata.
