Time to see just how many critters are there in a 1.9m tidal flow. There were quite few nudibranchs to see despite current. Surprise new species seeing Doriopsilla carneola after a Wrasse hit it from under an overhang! Discodoris cebuensis and Elysia sp. 17 were great to see come back after a year.

20 species sighted at Route 66, Mooloolah River, La Balsa Park, Buddina, Sunshine Coast, Queensland, Australia. 03-10-2025.

A single shore entry dive with Gary and Richard of 148 minutes, 1.6 m, maximum depth 4.9 m, 23 C water temperature, up to 8 m viz.

On this dive no Cratena pawarshindeorum were to be seen, in fact no Cratena were seen. And so the end of that great party has arrived. It was great to see a couple of Anteaeolidiella ireneae with spawn. Pleurobranchus peronii juvenile was another nice find. It seemed that the species count was a bit low.

Anteaeolidiella ireneae -2

Coryphellina pseudolotos -10
