Species List: 30-9-2017, Poor City, northern side of Old Woman Island, off Mudjimba, Sunshine Coast, Qld

23 species sighted at Poor City, northern side of Old Woman Island, off Mudjimba, Sunshine Coast, Qld, 30-9-2017.

Julie, Terry, Gary and David on this excursion consisting of 1 x 89 minute and 1 x 70 minute dives in water depths from 10 m to 13 m. 8 m viz, 22 C water temp and some occasional slight surge from a small northerly swell.

We headed to the north side of Old Woman Island to be on the leeward side for when the predicted 15 - 20 knot wind change that was forecast to come in late morning. As it unfolded no such change arrived. With a number of vessels in the vicinity of the sites we wanted we took pot luck and just dropped the pick randomly. There was a paucity of slugs to what we normally encounter but a couple of not-so-common species were amongst those including, Thuridilla albopustulosa, Elysia pusilla and Crimora sp. 1.
