The name is derived from Dirona Albolineata, or the Alabaster Nudibranch, an invertebrate indigenous to the Puget Sound that we often see when scuba diving. Over 3,000 Nudibranch species live throughout the world's oceans—their fantastic forms and psychedelic colors make them among our favorite sea creatures.
