Gary solo on this single shore entry dive, of 160 minutes. Maximum depth 6.5 m, 27 C water temperature.

Diving the River is very relaxing yet very rewarding. The more time you spend on the bottom the more you find. During this dive a very striking orange aeolid called Caloria sp. 1 was found, making our Species List 709 species.

Species List: 17-02-2017, Hancock Shoal, off Mt Peregian (Emu Mountain), Sunshine Coast, Qld.

51 species sighted at Hancock Shoal, off Mt. Peregian (Emu Mountain), Sunshine Coast, Qld, 17-02-2017.

Julie, Terry, Gary and David were joined by Sue & Rogan on this excursion consisting of 1 x 101 minute and 1 x 94 minute dives in water depths from 11 m to 13 m. 12 m viz, 27 C water temp and some surge.

Following the past week of unsettled weather we thoroughly enjoyed the conditions during the trip up to the Hancock Shoal. This area has proved to be one of remarkable diversity. Over 70 different species have been sighted during this and the previous trip there. On this trip we were rewarded with a new species - Discodoris coerulescens. This was revealed after the dives during a review of the images. It appears that we have found this species previously but it had been mixed up with another of our species namely Discodoris lilacina. Whilst similar in appearance there are a number of external differences the most obvious being the opaque white spots around the edge of the mantle.
