At these depths, the weight of water above equals the force of multiple jumbo jets pressing down on every square meter, yet this shark’s cartilage skeleton and flexible tissues withstand pressures that would crush most surface-dwelling animals.
By occupying this vertical frontier, the species connects deep benthic ecosystems with upper Arctic food webs, making it a rare example of a giant vertebrate thriving across environmental extremes that span pitch-black abyss to icy coastal shelves.
