Julie, David, Terry and Gary on this excursion consisting of 1 x 94 minute and 1 x 81 minute dives in water depths up to 13.4 m, 10 m viz, 20 C water temp.
Julie decided we should visit Arkrwright Shoals off Coolum so off we went. As we descended to the bottom it was apparent the clarity was a bit off. Finding and recording Nudibranchs was a challenge but we managed 41 species...another great outing. Eight species of Phyllidiid were recorded and 45 Doriprismatica atromarginata were found as well. The two very small Goniobranchus decorus were found from under a rock after we got back and viewed the photos.
