Articles relating to the Physeteroidea, a superfamily that includes three extant species of whales: the sperm whale, in the genus Physeter, and the pygmy sperm whale and dwarf sperm whale, in the genus Kogia. Additional fossil representatives of both families are known.
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.
Physeter is a genus of toothed whales.There is only one living species in this genus: the sperm whale (Physeter macrocephalus). [2] 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, [3] and Physeter vetus (2.6 mya – 12 ka) from the Quaternary of the U.S. state of Georgia.

Diaphorocetus was originally named Mesocetus by Moreno (1892). [2] Lydekker (1893) found that Mesocetus was already in use for an extinct mysticete, so he renamed the sperm whale Hypocetus. [3]

Two main hypotheses exist for use of the spermaceti organ: It assists in controlling buoyancy by manipulating the spermaceti oil's temperature and, consequentially, its density, facilitating deep diving by cooling and surfacing by warming, as well as allowing the animal to remain motionless at great depth.
