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]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
The head is bulbous, resembling that of a whale. [5] The shark is very small, at only 5.5 inches (140 mm). Near the gills are two "pockets" that secrete a luminous fluid which may enable the shark to hunt. [6] The body is grey with the fins being darker. The areas around the gills are cream colored. [7]

This can be accomplished by means of a swept-back mouth, as in balaenid whales, [21] or by allowing water to flow out through the gills, as in sharks and herring. A number of species have evolved narrow snouts, as in gar fish and water snakes. [22] Herrings often hunt copepods.
The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
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 ...
This places the beaked whales as some of the few food competitors of the sperm whale. Other possible squid predators include the pilot whale, killer whales, larger southern elephant seals, Patagonian toothfish, [40] southern sleeper sharks (Somniosus antarcticus), Antarctic toothfish, and albatrosses (e.g., the wandering and sooty albatrosses).
