25 species sighted at Bubble Wall Toilet Block and back, Mooloolah River, La Balsa Park, Buddina, Sunshine Coast, Queensland, Australia. 20-06-2026.
A single shore entry dive with Gary, David and Sheryl of 249 minutes, 1.2 m, maximum depth 6.3 m, 20 C water temperature, up to 4 m viz.
With a 1.2 m tidal flow it was time to check out the Bubble Wall and Toilet Block area. Boy were there a lot of Nudibranchs, probably a thousand could be seen! Armina sp. 1 was recorded today and is a new species. There appears to be no rhinophores and the longitudinal ridges are branched and converge at the anterior end of the mantle, pretty cool! Collected two Coryphellina sp. 9 (Coryphellina davidparkeri) now I have 3 specimens. Not the clear winter water we expected but great non the less. Great dive!
