Species List: 05-03-2020, Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

10 species sighted at Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld. 05-03-2020.

A single shore entry dive by Gary, Fran and Nevar of 252 minutes. Maximum depth 5.3 m, 28 C water temperature and up to 3 m viz.

Another mid-week dive and a beautiful warm morning. After our last dive we were ready to record all the Goniodoridella sp. 1. What amazes me is how robust and tuff Goniodoridella sp. 1 is. After a major flushing of the river which killed off nearly everything this species survives, not only survives but is mating in large numbers as well as egg masses every where. Recording 2 live Retusa sp. 5 was another highlight.

BTW after the last dive we added 3 new species - 903 species total, 376 species for the river.
