Species List: 04-01-2021, Fish Cage up river and down river, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

40 species sighted at Fish Cage up river and down river, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 04-01-2021.

A single shore entry night dive with Gary and David of 302 minutes. Maximum depth 5.3 m, 28 C water temperature, up to 4 m viz.

Another might dive was in order! It seems the water has cleaned up a little. More interesting critters were recorded. In particular a new record for the river in Thordisa verrucosa which has only been recorded once in 18 years. The highlight for me was finding a LIVE Ringicula sp. and to top that off an animal that is not white! Brown and blotchy the 2 mm shell is stout and white. Dendrodoris was out and about and quite large. David took out his UV light and aimed it at the Tenellia group on the top of the Fish Cage. The cerata lit up! And the most common was non-other than Atys semistriatus! That's cool.
