Species List: 21-11-2020, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

39 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 21-11-2020.

A single shore entry dive Gary, Fran and Nevar of 257 minutes. Maximum depth 5.7 m, 25 C water temperature, 4-8 m viz.

More Saturday daytime diving with tourists and cars everywhere. Despite that this dive presented some pretty clear water with little current. I would go so far as to saying this dive was EPIC! Three new species. After chatting with Bob Burn he has confirmed a new and very rare species Retusa complanata, he said he has never seen it. Goniodoridella savignyi still rules the river as far as number of animals go with Tenellia sp. 23 and Unidentia sp. 1 right behind. PS I always love seeing Limacia ornata and Knoutsodonta maugeansis!! EPIC!
