At 700 meters or more below the surface of the ocean, the lack of sunlight means food can be hard to come by. Some animals address the problem by eating extra-big meals that they swallow whole to make sure they don’t miss even a piece of their prey. One species, the black swallower, can gulp down a fish 10 times its own weight and up to four times its length. Two rows of large, pointed teeth on each jaw can collapse to make room as prey ratchets down the gullet, to be slowly digested in a stomach with expandable walls.
