Livyatan is the largest fossil sperm whale discovered, and was also one of the biggest-known predators, having the largest bite of any tetrapod.

Skull of Livyatan. Macroraptorial sperm whales were highly predatory whales of the sperm whale superfamily (Physeteroidea) of the Miocene epoch that hunted large marine mammals, including other whales, using their large teeth. They consist of five genera: Acrophyseter, Albicetus, Brygmophyseter, Livyatan and Zygophyseter. [1]
Arguably the most famous sperm whale counter-attack occurred on 20 November 1820, when a whale claimed to be about 25.9 metres (85 ft) long rammed and sank the Nantucket whaleship Essex. Only 8 out of 21 sailors survived to be rescued by other ships. [240] Scrimshaw was the art of engraving on the teeth of sperm whales. It was a way for whalers ...
Livyatan had a short and wide rostrum measuring 10 feet (3.0 m) across, which gave the whale the ability to inflict major damage on large struggling prey, such as other early whales. Species like these are collectively known as killer sperm whales or macroraptorial sperm whales .
Over the last five years, roughly 700 orca run-ins have been recorded, according to the Atlantic Orca Working Group-GTOA, a partnership of Spanish and Portuguese scientists that monitors the ...
For dramatic effect, Melville asserts inaccurately that the sperm whale is the largest creature on Earth. While the blue whale, the true largest whale, was not well-observed at that time, the fin-back whale, the second-largest whale species, was known to whalers and occasionally hunted. The sperm whale is the third-largest whale species. II.
The 2015 Ron Howard film was based on Nathaniel Philbrick’s 2000 nonfiction book of the same name, which investigates the 1820 sinking of a whaling ship that was caused by a sperm whale attack.
Zygophyseter could reach an estimated length of 6.5 to 7 meters (21 to 23 ft), compared to the 12.5-to-18.5-meter (41 to 61 ft) modern sperm whale. [11] It is thought that this whale had twelve thoracic vertebrae and at least ten lumbar vertebrae .
