Species List: 26-04-2019, Toilet Block, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

12 species sighted at Toilet Block, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 26-04-2019.

A single shore entry dive by Gary, David, Itai and Kyle of 133 minutes. Maximum depth 5.3 m, 23 C water temperature and up to 3 m viz.

Can't seem to get away from the river! After the surreal dive the other day we thought we would continue the search. Again the brown layer was on top and with a 1.1m tide the particles were hanging in the water column. The dive resembled a Martian landing...for all we nknew we were on Mars. Pteraeolidia semperi and Goniodoridella sp. 1 were again very common. From under rocks nice nudibranchs were found, Phyllodesmium opalescens and a couple of Cratena sp. 6. There was a golden hydroid with a slime of Tenellia sibogae. Some interesting flatworms and ovulids were found as well.
