14 species sighted at, Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 20-09-2018.

A single night shore entry dive by Gary and Jens of 119 minutes. Maximum depth 5.8 m, 21 C water temperature and up to 8 m viz.

Since the water quality has been so good Jens wanted to conduct a night dive and off we went. Finding a dozen Tenellia sp. 24 on the sandy bottom was surprising. These animals were very small and easy to see if you got low and slow. As for me I was really focusing on the sandy bottom searching small small nudibranchs. I was rewarded with a new species of Sagaminopteron pohnpei, our 761st species. Another interesting fact of the river lately is finding Okenia liklik, nearly all accounts of divers in the river have seen this species. And finding another Mnestia sp. with it's banded shell made for another successful excursion in the river.
