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.

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.
Male sperm whales are sexually mature at 11 to 12 meters (36 to 39 ft), and physically mature at about 15 to 16 meters (49 to 52 ft) in length, on average. Larger-than-average females have been generally recorded around 12 to 13 meters (39 to 43 ft), and larger-than-average males are usually stated to reach a maximum of about 18 to 19 meters ...
The spermaceti organ in sperm whales is shaped like an elongated barrel and sits on top of the whale's melon. Historically, the spermaceti oil found within it was used in a variety of products – including lamp oils, candles, and lubricants – providing the economic basis for the sperm whaling industry. [ 2 ]
• Physical maturity for female sperm whales is around 10.6 to 11 meters (35 to 36 ft) on average, whilst for male sperm whales, it is around 15 to 16 meters (49 to 52 ft) in length. Above-average females have been recorded up around 12 to 13 meters (39 to 43 ft), and the maximum size usually stated for males is males around 18 to 19 meters ...
Pygmy sperm whales and dwarf sperm whales are unique among cetaceans in using a form of "ink" to evade predation in a manner similar to squid. Both species have a sac in the lower portion of their intestinal tracts that contains up to 12 liters of dark reddish-brown fluid, which can be ejected to confuse or discourage potential predators. [30]
Size comparison between the sperm whale (blue), the pygmy sperm whale (green), and the dwarf sperm whale (orange) The dwarf sperm whale can range in size from 2 to 2.7 m (6.6 to 8.9 ft) in length and 136 to 272 kg (300 to 600 lb) in weight—less than the 4.25 m (14 ft) and 417 kg (920 lb) pygmy sperm whale.
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.
