The toothed whales (also called odontocetes, systematic name Odontoceti) are a clade of cetaceans that includes dolphins, porpoises, and all other whales with teeth, such as beaked whales and the sperm whales. 73 species of toothed whales are described.
The tooth was inscribed: "This is the tooth of a sperm whale that was caught near the Galápagos Islands by the crew of the ship Adam [of London], and made 100 barrels of oil in the year 1817." [5] Other sea animal ivories were used as alternatives to the rarer whale teeth.
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales. Depending on the species, a baleen plate can be 0.5 to 3.5 m (1.6 to 11.5 ft) long, and weigh up to 90 kg (200 lb). Its hairy fringes are called baleen hair or whalebone hair.
The sperm whale has 18 to 26 teeth on each side of its lower jaw which fit into sockets in the upper jaw. [56] The teeth are cone-shaped and weigh up to 1 kilogram (2.2 lb) each.

Consequently, its tooth count was lower than those sperm whales, and, aside from the modern dwarf (Kogia sima) and pygmy (K. breviceps) sperm whales, it had the lowest tooth count in the lower jaw of any sperm whale. [1] [8] The most robust teeth in Livyatan were the fourth, fifth and sixth teeth in each side of the jaw. The well-preserved ...
