Colorful and relatively plentiful – when we dove the Channel Islands, J and I found many of these colorful nudibranch. They are small, no more than an inch long. The water is deceptively cloudy and dark, enough to push the ISO to 1600. We saw them and got a number of shots but few were really good. J got one and I consider it to be the best of the day for this nudibranch. There are red horns and blue horns at the head. She nailed the shot. I’m very happy she shared this with me.
