Julie, Terry and David on this excursion consisting of 1 x 83 minute and 1 x 85 minute dives in water depths of 11 m to 14 m. 6 m viz, 18 C water temp and some surge. We all agreed that the drysuit is the best invention ever.
Once more the island beckoned. With the NW wind forecast to strengthen we opted to dive on the SE corner at a site we call Bornella Reef. Whilst there were hydroids present alas the Bornella specimens that gave their name to the site were not. Two specimens of Tambja victoriae were sighted one of which at 60 mm was amongst the largest we have observed in these waters. Favorinus sp. 1 popped up again. It has been placed in this genus for the sole reason that the rhinophores have cup-shaped annulations but the cerata do not seem typical.
