Ivory is a hard, white material from the tusks and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed.
Walrus ivory, also known as morse, comes from two modified upper canines of a walrus. The tusks grow throughout life and may, in the Pacific walrus, attain a length of one metre. Walrus teeth are commercially carved and traded; the average walrus tooth has a rounded, irregular peg shape and is approximately 5 cm in length.
Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with narwhals, chevrotains, musk deer, water deer, muntjac, pigs, peccaries, hippopotamuses and walruses, or, in the case of elephants, elongated incisors. Tusks share common features such as extra-oral position, growth pattern, composition and structure, and lack of contribution to ingestion. Tusks are thought to have adapted to the extra-oral environments, like dry or aquatic or arctic. In most tusked species both the males and the females have tusks although the males' are larger. Most mammals with tusks have a pair of them growing out from either side of the mouth. Tusks are generally curved and have a smooth, continuous surface. The male narwhal's straight single helical tusk, which usually grows out from the left of the mouth, is an exception to the typical features of tusks described above. Continuous growth of tusks is enabled by formative tissues in the apical openings of the roots of the teeth.
A netsuke is a miniature sculpture, originating in 17th century Japan. Initially a simply-carved button fastener on the cords of an inrō box, netsuke later developed into ornately sculpted objects of craftsmanship.
The sperm whale or cachalot 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.
This article discusses the history of whaling from prehistoric times up to the commencement of the International Whaling Commission (IWC) moratorium on commercial whaling in 1986. Whaling has been an important subsistence and economic activity in multiple regions throughout human history. Commercial whaling dramatically reduced in importance during the 19th century due to the development of alternatives to whale oil for lighting, and the collapse in whale populations. Nevertheless, some nations continue to hunt whales even today.
A tabua is a polished tooth of a sperm whale that is an important cultural item in Fijian society. They were traditionally given as gifts for atonement or esteem, and were important in negotiations between rival chiefs. The dead men would be buried with their tabua, along with war clubs and even their strangled wives, to help them in the afterlife. Originally they were very rare items, available only from beached whales and from trade from neighbouring Tonga, but when the market became known in the early 19th century thousands of teeth, and fake teeth made from ivory and walrus tusks entered the market. This trade led to the development of the European art of scrimshaw.
Pequod is a fictional 19th-century Nantucket whaling ship that appears in the 1851 novel Moby-Dick by American author Herman Melville. Pequod and her crew, commanded by Captain Ahab, are central to the story, which, after the initial chapters, takes place almost entirely aboard the ship during a three-year whaling expedition in the Atlantic, Indian and South Pacific oceans. Most of the characters in the novel are part of Pequod's crew.
Ivory carving is the carving of ivory, that is to say animal tooth or tusk, generally by using sharp cutting tools, either mechanically or manually. Objects carved in ivory are often called "ivories".
The Whaling Museum & Education Center, formerly known as The Whaling Museum, is a maritime museum located in Cold Spring Harbor, New York dedicated to the local history, the maritime heritage of Long Island and its impact on the whaling industry.
Bone carving is creating art, tools, and other goods by carving animal bones, antlers, and horns. It can result in the ornamentation of a bone by engraving, painting or another technique, or the creation of a distinct formed object. Bone carving has been practiced by a variety of world cultures, sometimes as a cheaper, and recently a legal, substitute for ivory carving. As a material it is inferior to ivory in terms of hardness, and so the fine detail that is possible, and lacks the "lustrous" surface of ivory. The interior of bones are softer and even less capable of a fine finish, so most uses are as thin plaques, rather than sculpture in the round. But it must always have been much easier to obtain in regions without populations of elephants, walrus or other sources of ivory.
Whaling in Australian waters began in 1791 when five of the 11 ships in the Third Fleet landed their passengers and freight at Sydney Cove and then left Port Jackson to engage in whaling and seal hunting off the coast of Australia and New Zealand. The two main species hunted by such vessels in the early years were right and sperm whales. Humpback, bowhead and other whale species would later be taken.
Alaska Native cultures are rich and diverse, and their art forms are representations of their history, skills, tradition, adaptation, and nearly twenty thousand years of continuous life in some of the most remote places on earth. These art forms are largely unseen and unknown outside the state of Alaska, due to distance from the art markets of the world.
Commercial whaling in the United States dates to the 17th century in New England. The industry peaked in 1846–1852, and New Bedford, Massachusetts, sent out its last whaler, the John R. Mantra, in 1927. The Whaling industry was engaged with the production of three different raw materials: whale oil, spermaceti oil, and whalebone. Whale oil was the result of "trying-out" whale blubber by heating in water. It was a primary lubricant for machinery, whose expansion through the Industrial Revolution depended upon before the development of petroleum-based lubricants in the second half of the 19th century. Once the prized blubber and spermaceti had been extracted from the whale, the remaining majority of the carcass was discarded.
Nantucket shipbuilding began in the late 1700s and culminated in the construction of notable whaling ships during the early 19th century. Shipbuilding was predominantly sited at Brant Point. Whaling ship construction concluded in 1838.
Sperm whaling is the human practice of hunting sperm whales, the largest toothed whale and the deepest-diving marine mammal species, for the oil, meat and bone that can be extracted from the cetaceans' bodies.

The Nantucket Whaling Museum is a museum located in Nantucket, Massachusetts. It is run by the Nantucket Historical Association. The Whaling Museum is the flagship site of the Nantucket Historical Association’s fleet of properties.
The conservation and restoration of ivory objects is the process of maintaining and preserving objects that are ivory or include ivory material. Conservation and restoration are aimed at preserving the ivory material and physical form along with the objects condition and treatment documentation. Activities dedicated to the preservation of ivory objects include preventing agents of deterioration that specifically connect with ivory as a material, preventative conservation, and treatment of ivory objects. Conservators, curators, collections managers, and other museum personnel are in charge of taking the necessary measurements to ensure that ivory objects are well maintained and will make the decision for any conservation and restoration of the objects.
