Brygmophyseter, known as the biting sperm whale, is an extinct genus of toothed whale in the sperm whale family with one species, B. shigensis. When it was first described in 1994, the species was placed in the genus Scaldicetus based on tooth morphology , but this was later revised in 1995.
The fact that the bite marks were found on the tooth's roots further suggest that the shark broke the whale's jaw during the bite, suggesting the bite was extremely powerful. The fossil is also notable as it stands as the first known instance of an antagonistic interaction between a sperm whale and an otodontid shark recorded in the fossil record.
The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.

Now, sperm whales are protected under the Marine Mammal Protection Act. So, in order to sell the animal's tooth, it must be over 100 years old, and the owner has to know where it's been since the ...
It was a member of a group of macroraptorial sperm whales (or "raptorial sperm whales") and was probably an apex predator, preying on whales, seals and so forth. Characteristically of raptorial sperm whales, Livyatan had functional, enamel -coated teeth on the upper and lower jaws, as well as several features suitable for hunting large prey.
The ancient shark, which grew up to 65ft long and weighed over 50 tons, ate sperm whales by ripping off their heads with its huge teeth, a new study has shown. The ancient shark, which grew up to ...
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).
