Over the years, new species have been found and existing species have been moved to other genera while other species are new.

The 2012 Nudibranch Safari at Gulen Dive Resort was a phenomenal success. A staggering 49 species of nudibranchs and seven other ophistobranchs were identified during the weekend—on one divespot.

The jet-black rubber RIB was running flat out in the February night. We were sweeping past the Mongstad oil refinery at the Norwegian west-coast, just south of Gulen Dive Resort, and the clock was approaching midnight. Apart from the lights in the distance, the visibility was zero, and we were navigating solely on GPS, chart plotter and radar. The speed of 35 knots produced a howling wind, although the sea was completely calm.
