The Atacama Trench, also known as the Peru-Chile Trench, runs roughly 3,700 miles along the western edge of South America. D. camanchaca has been recorded in only one place, but it’s hard to rule out the possibility that it might also live somewhere else. And while nobody has yet watched D. camanchaca eat, its body is clearly built for violence. But the two-inch-long D. camanchaca is able to live there, molting, swimming, and hunting under a load that would flatten most creatures. In early 2026, the Joint China-Chile Atacama Trench Expedition put Fendouzhe—a crewed submersible rated for extreme ocean depths—into the trench with scientists inside it.
