David and Gary on this excursion consisting of 2 x 72 minute dives in water depths up to 17.6 m, 20 m viz, 20 C water temp.
A visit to one of the popular gutter dive sites proved rewarding. Only half the Team was present today and we recorded some very interesting nudibranchs. The elusive 'Blue Tambja' or Tambja caeruleocirrus 40 mm was found again as well as Aegires hapsis 10 mm. In 15 years we have only recorded these two species 5 times.
Again winter and the lack of rain has brought very clear water to our 'backyard'. 20 C water temps seem to be the norm this winter so far with August getting a little cooler.
