Livyatan is an extinct genus of macroraptorial sperm whale containing one known species: L. melvillei.The genus name was inspired by the biblical sea monster Leviathan, and the species name by Herman Melville, the author of the famous novel Moby-Dick about a white bull sperm whale.
Livyatan probably targeted medium-sized whales ranging in size from 7–10 m (23–33 ft). Macroraptorials probably competed with the extinct giant shark megalodon for the same food sources. [7] [10] [11] [12] In sperm whales, the supracranial basin holds the spermaceti organ, a series of oil and wax reservoirs which aids in echolocation.
The lumbar vertebrae were elongated and may have supported large multifidus and longissimus muscles in the back, likely larger than the modern sperm whale, and so it probably swam faster than the modern sperm whale; [1] the modern sperm whale typically travels horizontally at 4 kilometers per hour (2.5 mph), comparable to other large open-ocean ...
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.
Some balaenopterids perhaps rivaled the blue whale in terms of size, [114] though other studies disagree that any baleen whale grew that large in the Miocene. [115] The true largest macroraptorial sperm whale is none other than the Livyatan, with an estimated length of 44–57 ft (13.5–17.5 m) and an estimated weight of 62.8 short tons (57 ...
Livyatan melvillei is an extinct species of sperm whale that lived about 9.9 to 8.9 million years ago, during the Miocene epoch. The name was inspired by the biblical sea monster Leviathan, and Herman Melville, the author of Moby-Dick. It was probably an apex predator, preying on whales and seals.
The Snake Diet is an extreme intermittent fasting diet where you drink Snake Juice. Drastic before and after weight-loss results make it tempting, but experts say it's not the best diet. The Snake ...
The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
