Today was Nudibranch Day at Sunreef. The weather was marginal so we opted for the protected side od Old Woman Island. Great vis but some surge. Someinteresting species were found including a very large Hexabranchus sanguineus. The highlight for me was finding 2 Crimora edwardsi from under a rock.

A single solo night/morning shore entry dive Gary of 210 minutes. Maximum depth 5.6 m, 19 C water temperature up to 6 m viz.

Mid-week diving early in the morning, tastes good! The water was pretty clean some interesting species were recorded. The highlight for me was finding the shell of Diacavolinia longirostris...always great to find evidence of a pelagic species. Yes I sat up with the light aiming into the current - but did not see live animals. Two Elysia species were recorded as well. Goniodoridella savignyi was everywhere while Goniodoridella sp. 1 only a few. Two Embletonia gracilis were nice to find with a clear white lines on the body. Seeing Plocamopherus tilesii again was also a great find. Good dive!
