But National Geographic says, "Sperm whales are known to dive as deep as 3,280 feet in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives."
However, the amount of fish taken is very little compared to what the sperm whale needs per day. Video footage has been captured of a large male sperm whale "bouncing" a long line, to gain the fish. [163] Sperm whales are believed to prey on the megamouth shark, a rare and large deep-sea species discovered in the 1970s. [164]
An alternate theory is that sperm whales, including Livyatan, can alter the temperature of the wax in the organ to aid in buoyancy. Lowering the temperature increases the density to have it act as a weight for deep-sea diving, and raising the temperature decreases the density to have it pull the whale to the surface. [1] [3] [8]
The deep sea anglerfish and dragonfish attracts prey, and fangtooths eat fish and squid. In the deep, a sperm whale carcass attracts many scavengers, such as bluntnose sixgill sharks, spider crabs, rock crabs, and osedax; as well as the scavenger's predators, including silver scabbardfish.
