Moby-Dick; or, The Whale is an 1851 epic novel by American writer Herman Melville. The book centers on the sailor Ishmael's narrative of the maniacal quest of Ahab, captain of the whaling ship Pequod, for vengeance against Moby Dick, the giant white sperm whale that bit off his leg on the ship's previous voyage. A contribution to the literature of the American Renaissance, Moby-Dick was published to mixed reviews, was a commercial failure, and was out of print at the time of the author's death in 1891. Its reputation as a Great American Novel was established only in the 20th century, after the

Kogiidae is a family comprising at least two extant species of Cetacea, the pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales. As their common names suggest, they somewhat resemble sperm whales, with squared heads and small lower jaws, but are much smaller, with much shorter skulls and more notable dorsal fins than sperm whales. Kogiids are also characterized by a "false gill slit" behind their eyes.

Kogia is a genus of toothed whales within the superfamily Physeteroidea comprising two extant and two extinct species from the Neogene:

Physeter is a genus of toothed whales. There is only one living species in this genus: the sperm whale (Physeter macrocephalus). Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus (5.3–2.6 mya) from the Pliocene of France, and Physeter vetus (2.6 mya – 12 ka) from the Quaternary of the U.S. state of Georgia. Physeter vetus is very likely an invalid species, as the few teeth that were used to identify this species appear to be identical to those of another toothed whale, Orycterocetus quadratidens.

Scaldicetus is an extinct genus of highly predatory macroraptorial sperm whale. Although widely used for a number of extinct physeterids with primitive dental morphology consisting of enameled teeth, Scaldicetus as generally recognized appears to be a wastebasket taxon filled with more-or-less unrelated primitive sperm whales.
