Species List: 19-12-2021, Fish Cage to Rotunda, La Balsa Park, Buddina, Sunshine Coast, Queensland, Australia.

 33 species sighted at Fish Cage to Rotunda, La Balsa Park, Buddina, Sunshine Coast, Queensland, Australia. 19-12-2021.

A single solo shore entry dive with Gary of one 306 minute dive. Maximum depth 6.1 m, 27 C water temperature, up to 8 m viz.

Early Sunday diving how good is that? The 1.9m tidal flow was healthy but do-able! Gymnodoris was out to play with 2 new ones. The differences involve the organs showing through the body and how they are situated etc. Recording five Dendrodoris arborescens was a treat. A juvenile Knoutsodonta maugeansis was so small I had to try and move it to be sure. Flabellina lotos is still dominating the substrate. Unidentia species are on the decline. Tenellia species are hanging by a thread with very little food.
