One common theory is that the fluid—which hardens to wax when cold—helps the whale alter its buoyancy so it can dive deep and rise again." And sperm whales function as a family, "Sperm whales ...
Ecologists raise concerns about whale’s deteriorating health after it beached over weekend
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.
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]
They have also been reported to eat some deep-sea shrimps, but, compared with dwarf sperm whales, relatively few fish. [9] Predators may include great white sharks [28] and killer whales. [29] Pygmy sperm whales and dwarf sperm whales are unique among cetaceans in using a form of "ink" to evade predation in a manner similar to squid.

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]
Sperm whales, Sharma said, also use a two-level combination of features to form codas, and codas are then sequenced together as the whales communicate. The lower level has similarities to letters ...
