COMMENTS & OBSERVATIONS

The swell was still persisting on the Caloundra Bar so we ventured out of the Mooloolah River once more. The destination this time was again, the Outer Gneerings, but we selected Aquarium, quite near to Coles Hole, as the dive site as It provides a range of depths. The surge had abated somewhat from the weekend making the dive more relaxing. Favorinus sp. 02, Glossodoris aeruginosa & Colpodaspsis thompsoni were not-so-common finds. Chromodoris elisabethina seems quite abundant on the Outer Gneerings at present.

Taxonomic Diversity:
Of the total species sighted 18 of the 25 were dorids with 8, almost half, belonging to the Chromodorididae family and a further 9, exactly half, belonging to the Phyllidiidae family = 17 of the 18 dorids coming from just these two families.

Our Historical Data:
