"These nudibranchs are one of my favorite models for underwater photo sessions. I call them “the vivid colors of the sea” or “snow queens.” Here, Phyllodesmium iriomotense can be seen feeding on one of its favorite dishes: spindly gorgonian coral. This photo was taken at a depth of 32 meters (105 feet). The time allotted for photography is very limited at that depth, so I did four dives in order to get this photo."
