Bottlehead

Bottlehead, Bottlenose, or Beuked Whale, a popular name for either of the two species of the genus Hyperoodon, from the peculiar shape of the head, caused by the elevation of the bones of the upper jaw. These whales are found in the North Atlantic, frequenting the Spitzbergen seas in summer, and passing south in winter. They vary in colour, from black in the young to light-brown in the older animals; all are greyish-white beneath. A large specimen may attain a length of 30 feet. The oil from the head yields a kind of spermaceti when refined, and that from the blubber is scarcely distinguishable from sperm-oil.
