The Coffinfish: The Inflatable Corpse of the Deep

The Coffinfish is not just a weird face of the deep — its enormous, inflatable gill chambers let it hold oxygenated water and literally “hold its breath” for minutes, changing how it moves, hunts, and survives in the abyss. This film unpacks the anatomy, the ROV footage, and the study that first revealed this breath-holding behavior. Support our dives and research access here: https://www.patreon.com/AnimalMystery
