Species List: 01-06-2019, Toilet Block, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

15 species sighted at Toilet Block, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 01-06-2019.

A single shore entry dive by Gary, Sheryl and Jenny of 123 minutes. Maximum depth 6.9 m, 20 C water temperature and up to 10 m viz.

After waking up to a chilly 4C degree morning to bottom of the river we went in darkness. The water temp has dropped to 20C and the current was low. On top of that there were times that seemed to be 8-10 m of vis. The early morning light presented a beautiful low light blue with the surface clearly seen from the bottom. Pteraeolidia semperi is still the most common at this site and after recording a rather large egg mass the population is sure to grow. Chromodoris sp. 5 was a great find from under a rock. And a small but colourful Philinopsis speciosa was also recorded.
