POPULAR MECHANICS " NEW PREDATOR FOUND IN ATACAMA TRENCH
Excerpt: while nobody has yet watched D. camanchaca eat, its body is clearly built for violence. It has a slender, fast-looking frame, mouthparts made for shredding rather than filtering, and a pair of oversized, grasping front limbs that work like spring-loaded claws. In most amphipods, those limbs are unremarkable. But in D. camanchaca, they dominate the animal’s front end, which is the anatomical signature of something that grabs living prey instead of waiting for a dead whale to drift down.
At 25,925 feet, the water presses down at roughly 790 times the atmospheric pressure at sea level. But the two-inch-long D. camanchaca is able to live there, molting, swimming, and hunting under a load that would flatten most creatures. Precisely how it manages that isn’t yet fully understood.
“This finding underlines the importance of continued deep-ocean exploration particularly in Chile’s front yard,” IMO’s Carolina González, co-lead author of the study, said in a press statement “More discoveries are expected as we continue to study the Atacama Trench.”
