Species List: 30-11-2019, Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

40 species sighted at Rotunda upriver, La Balsa Park, Mooloolah River, Sunshine Coast, Queensland, Australia, 30-11-2019.

A single shore entry dive by Gary, Fran, Never and David of 224 minutes. Maximum depth 5.8 m, 25 C water temperature and up to 6 m viz.

The last day of spring brings us to the river and we begin our search for nudibranchs. Yet again some very interesting species were found. From under a rock a 3 mm animal was found, at the time of the shooting I wrote it off as a sponge. After reviewing the photo post dive that animal looks much like a very juvenile Melibe species, complete with sensory hairs on the front of the oral veil...for the record here it is. Myja longicornis was also found and as usual it brought a lot of attention and bewilderment.
