I was out on the boat yesterday diving at Ene'nu'i dive spot at Molokini. We had some swell but the fish were out in force. Very close to the mooring is a rock covered with a black sponge and 2 large Black Margin Nudibranchs. The are only observed a handful of times in Hawaii but are common in Indonesia, etc. These nudibranchs have been there for a few years now and have been observed laying eggs.
I was taking photos with a 105 mm lens with a diopter. It was very hard to get a shot since the nudis are in a tight crack and you have to shoot up... Next time I'll try to get more photos.
