Species List: 01-09-2018, Nudi Ledge, Caloundra, Sunshine Coast, Qld

49 species sighted at Nudi Ledge, Caloundra, Sunshine Coast, Qld, 01-09-2018.

Julie, Terry, David and Gary on this excursion consisting of 1 x 79 minute and 1 x 78 minute dives in water depths up to 18.0 m, 15 m viz, 20 C water temp and hardly any surge.

The first day of spring obviously brings us more Nudibranchs to find and record. At first the winds were a bit of a worry but that didn't stop us. Fairly clear water was a treat. Again Doriprismatica atromarginata was in abundance with 38 animals recorded. 5 species of Verconia was also the result of good hunting. The total animals recorded was 190...let's go again!
