Julie, Terry, Gary and David on this excursion consisting of 1 x 70 minute and 1 x 71 minute dives in water depths from 16 m to 20 m. 15 m viz, 24 C water temp and a little surge.
Conditions were much improved compared to our excursion out to the Gneerings last week. Very pleasant dives on interesting terrain and a good cross section of sea slugs were sighted. A little deeper in parts than our usual profile. The outstanding find of the trip was Euselenops luniceps and not so much as a species but rather by the way it was sighted. On the ascent after the first dive it was observed to be swimming in the water column at 10 metres depth. Doris sp. 1 is only sighted rarely and the Phyllidiopsis xishaensis only once before by us. We follow Yonow, 2002 in giving it this name.
