Beautiful Characteristic Spiral of Iridogorgia Corals
From this video, which shows the beautiful characteristic spiral of Iridogorgia corals, it’s not hard to see why these corals are sometimes likened to fireworks. This genus of deep-sea corals is in the family Chrysogorgiidae. This one was seen with a squat lobster associate during the fifth dive of the 2026 American Samoa ROV + Mapping Exploration expedition.
