The dwarf sperm whale is a small whale, 2 to 2.7 m (6 ft 7 in to 8 ft 10 in) and 136 to 272 kg (300 to 600 lb), that has a grey coloration, square head, small jaw, and robust body. Its appearance is very similar to the pygmy sperm whale, distinguished mainly by the position of the dorsal fin on the body–nearer the middle in the dwarf sperm ...
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.
The pygmy sperm whale was first described by naturalist Henri Marie Ducrotay de Blainville in 1838. He based this on the head of an individual washed up on the coasts of Audierne in France in 1784, which was then stored in the Muséum d'histoire naturelle. He recognized it as a type of sperm whale and assigned it to the same genus as the sperm ...
Cetus is not among the 12 true zodiac constellations in the J2000 epoch, nor classical 12-part zodiac.The ecliptic passes less than 0.25° from one of its corners. Thus the moon and planets will enter Cetus (occulting any stars as a foreground object) in 50% of their successive orbits briefly and the southern part of the sun appears in Cetus for about one day each year.
Kogia is a genus of toothed whales within the superfamily Physeteroidea comprising two extant and two extinct species from the Neogene: Pygmy sperm whale, Kogia breviceps; Dwarf sperm whale, Kogia sima †Kogia pusilla, Italy, Middle Pliocene †Kogia danomurai Pisco Formation, Peru, latest Miocene; also known as the Small Sperm Whale.
The Dwarf sperm whale (Kogia sima), like its close relative the Pygmy Sperm Whale (K. breviceps), is a rather small species (2.7 m maximum) with a chubby, discreet appearance and a mainly tropical distribution. [42]
List of cetaceans. Cetacea is an infraorder that comprises the 94 species of whales, dolphins, and porpoises. It is divided into toothed whales (Odontoceti) and baleen whales (Mysticeti), which diverged from each other in the Eocene some 50 million years ago (mya). Cetaceans are descended from land-dwelling hoofed mammals, and the now extinct ...
Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the largest known animal that has ever lived. The sperm whale is the largest toothed predator on Earth.
