A single shore entry dive by Julie, Terry, Gary and David of 118 minutes. Maximum depth 6.9 m, 21 C water temperature and up to 5 m viz.
The whole Team was in attendance for this River dive. A reasonable species count was compiled. Many Gymnodoris were sighted across four different species which begs the question: What sea slugs are they preying upon? Two specimens of a nudibranch only recorded once by us before, Goniodoridella sp. 5, were found. 6 aeolids, 3 Chromodorididae, 4 Gymnodorididae, 3 Goniodoididae
