Species List: 09-09-2016, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Queensland

14 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast.

Julie, Terry, Tom Davis on this single shore entry dive of 99 minutes. Maximum depth 5.8 m, 20 C water temperature and 5 m viz.

It was nice to be able to show Tom over one of our favourite sites. He has always been willing to show us around when we have been in Nelson Bay and it was good to be able to return the favour.  Our species count is down a little on what we usually see here but we put this down to a bit of sightseeing instead of committed slug hunting.

Species List: 03-09-2016, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Queensland

Julie, Terry, Gary & David on this single shore entry dive of 105 minutes. Maximum depth 5.9 m, 21 C water temperature and 5 m viz.

A good haul for the river with 26 species of which exactly half are aeolids. Trinchesia sp. 17 is an uncommon species that seems to turn up every couple of years - first time in the river though. We also recorded a juvenile dorid that we are unable to match at this stage.
