Species List: La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Queensland, 28-03-2016

8 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Queensland.

Gary, Julie and Terry on this single, shore entry dive of 146 minutes. Maximum depth 5.5  m, 26 C water temperature and 5 m viz. The number and variety of species were down on our usual findings, however there were some interesting finds nonetheless.  This was only the second time we have seen Aglaja sp. 3 - at only 2 mm a very difficult critter to find.

Species List: Point Cartwright intertidal, Buddina, Sunshine Coast, Queensland, 27-03-2016

3 species sighted at the intertidal area at Point Cartwright, Sunshine Coast, Australia. Overcast day with a few showers, little wind. We spent most of our time searching the rocks close to the Mooloolah River mouth.  The rocks here are well embedded in the sand and this may have contributed to the relatively low numbers of species sighted.

Species List: TJs Boulders, Currimundi Reef, Sunshine Coast, Queensland, 24-03-2016

23 species sighted at TJs Boulders, Curriumundi Reef, Sunshine Coast, Queensland.

Gary and Terry on this excursion consisting of 1 x 72 minute and 1 x 69 minute dive in water depths of 15 m to 20 m. 8 m viz, 26 C water temp and some surge.

The swell had built a little since our last dive so we made the decision to venture to this slightly deeper site to try to avoid the worst of the surge. The surge was still strong at times and this possibly explains the slightly lower than usual species count for the area.  The Pteraeolidia semperi were present everywhere and our species count probably underestimates their relative abundance.  A nice find were the Phestilla melanobranchia which can be easy to miss because of their excellent camouflage.
