Species List: Forskalii Park, Currimundi Reef, Caloundra, Sunshine Coast, 25-06-2015

25 species sighted at Forskalii Park, Currimundi Reef, Caloundra, Sunshine Coast.

Julie, Terry and David on this excursion consisting of 1 x 94 minute and 1 x 80 minute dives in water depths of 8 m to 11 m. 10 m viz, 20 C water temp and surge.

Having experienced good visibility the day before we decided to try closer to shore on some shallower sections of the reef. We were again fortunate with the visibility and numbers of sea slugs sighted but had to contend with significant surge on the shallower plateau. Although the overall species count is similar more than a third were different to those of the previous day.

Species List: TJ's Boulders, Currimundi Reef, Sunshine Coast, 24-06-2015

26 species sighted at TJ's Boulders, Currimundi Reef, Caloundra, Sunshine Coast.

Terry and David on this excursion consisting of 1 x 79 minute and 1 x 70 minute dives in water depths of 15m to 20m. 12m viz, 20C water temp and a little surge.

Finally, we have been rewarded with a decent species count. Nothing new, nothing startling just a good cross section of sea slugs. TJ's Boulders is one of the deeper Currimundi sites and provides an agreeable variety of depth contours. The first dive presented us with large numbers of adult Pteraeolidia ianthina and Flabellina rubrolineata. Also sighted was an unusual phyllidiid. It is listed and shown below as Phyllidiella sp. We assign no number to it at this stage because we are not at all sure it is a separate species. The rhinophores are predominately black with a clear translucent base, the tubercles are high and angular and some are compound whilst others are individual. It does not entirely fit the description of any of Phyllidiella lizae, Phyllidiella pustulosa, Phyllidiella cooraburrama or Phyllidiopsis krempfi.

Species List: Northside of Old Woman Island, off Mudjimba, Sunshine Coast, 20-06-2015

19 species sighted on the Northside of Old Woman Island, Sunshine Coast.

Tom & Nicola Davis of Nelson Bay, NSW fame were up in Queensland this weekend so they joined us on one of our typical excursions. They sure are hardy souls down that way. Tom matched our bottom times in his wetsuit with us in our drysuits. No complaints even when the promised hot shower didn't work post dive.

Terry, Julie, Tom Davis & David on this excursion consisting of 1 x 88 minute and 1 x 75 minute dives in water depths of 9 m to 11.5 m. Visibility of 6 m, 20 C water temperature and some slight & intermittent surge. Nicola opted to provide excellent surface support having just shaken off a cold.

A strong wind warning was forecast with SW winds to swing around to the SE. Based on previous experience and monitoring of the BOM local wind modelling we considered the north side of Old Woman Island to be the most comfortable location and so it proved to be. Finding slugs proved to be hard work with their numbers still in short supply. Visibility dropped to about 3 m during the 2nd dive. The Pleurolidia juliae was a good find and photos were taken with its spirally wound egg masses evident.
