Species List: 15-10-2019, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

40 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, La Balsa Park, Sunshine Coast, Queensland, Australia, 15-10-2019.

A NEW RECORD for recorded species in the river.

A single shore entry dive by Gary and Brenton of 176 minutes. Maximum depth 5.9 m, 22 C water temperature and up to 7 m viz.

We decided to drift up river to the first bench and descended. It appeared that there were nudibranchs everywhere. On this dive we broke the record for recorded species in the river at 40 (as far as I know). Another new species was recorded, similar but different. Doto sp. 6 were in large colonies at the base of their hydroid food source. Goniodoridella savignyi  were the most common today. And of course seeing 2 Phyllodesmium undulatum was a great sight and finding another Colpodaspis sp. 1 was also great to see

Species List: 13-10-2019, the Trench, Gneering Shoals, Mooloolaba, Sunshine Coast, Qld.

37 species sighted at the Trench, Gneering Shoals, Mooloolaba, Sunshine Coast, Queensland, Australia, 13-10-2019.

A Sunreef Nudibranch Day double boat dive by Gary, David, Brenton, Tracy, Harvey and Rach of 58 and 57 minutes. Maximum depth 18.9 m, 22 C water temperature and 8-10 m viz.

Another fair weather Sunreef Nudibranch Day. A boat load of divers wanting to learn more about our favourite animals. The anchor was dropped perfectly and down we went, no new species but some interesting ones non the less. For me the finding of Tambja caeruleocirrus was great as well as Cadlinella ornatissima. A great day out and a good list of species.
