A single shore entry dive by Gary and Gail of 160 minutes. Maximum depth 6.9 m, 25 C water temperature and up to 4 m viz.
A sunny warm day was predicted and to the Toilet Block site we went. Today's dive did not disappoint with 163 nudibranchs found and 2 new records for this diverse river. A big surprise was finding 2 Bornella anguilla in the golden hydroid with Tenenllia sibogae. Rock turning was very productive. A very long Ceratosoma tenue was crawling on the substrate with it's single rhinophore.
