Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope. Spermaceti, a Highly Regarded Oil A peculiar oil found in the head of the sperm whale, spermaceti, was highly prized. The oil was waxy, and was commonly used in making candles. In fact, candles made of spermaceti were considered the best in the world, producing a bright clear flame without an excess of smoke. Spermaceti was also used, distilled in liquid form, as an oil to fuel lamps. The main American whaling port, New Bedford, Massachusetts, was thus known as "The City That Lit the World." When John Adams was the ambassador to Great Britain before serving as president he recorded in his diary a conversation about spermaceti he had with the British Prime Minister William Pitt. Adams, keen to promote the New England whaling industry, was trying to convince the British to import spermaceti sold by American whalers, which the British could use to fuel street lamps. The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s. And spermaceti was a major component of that success. Spermaceti could be refined into a lubricant that was ideal for precision machinery. The machine tools that made the growth of industry possible in the United States were lubricated, and essentially made possible, by oil derived from spermaceti. Whalebone The bones and teeth of various species of whales were used in a number of products, many of them common implements in a 19th century household. Whales are said to have produced “the plastic of the 1800s.” The bone of the whale which was most commonly used wasn’t technically a bone, it was baleen, a hard material arrayed in large plates, like gigantic combs, in the mouths of some species of whales. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. As baleen was tough yet flexible, it could be used in a number of practical applications. And it became commonly known as whalebone. Perhaps the most common use of whalebone was in the manufacture of corsets, which fashionable ladies in the 1800s wore to compress their waistlines. One typical corset advertisement from the 1800s proudly proclaims, “Real Whalebone Only Used.” Whalebone was also used for collar stays, buggy whips, and toys. Its remarkable flexibility even caused it to be used as the springs in early typewriters. The comparison to plastic is apt. Think of common items which today might be made of plastic, and it's likely that similar items in the 1800s would have been made of whalebone. Baleen whales do not have teeth. But the teeth of other whales, such as the sperm whale, would be used as ivory in such products as chess pieces, piano keys, or the handles of walking sticks. Pieces of scrimshaw, or carved whale's teeth, would probably be the best remembered use of whale's teeth. However, the carved teeth were created to pass the time on whaling voyages and were never a mass production item. Their relative rarity, of course, is why genuine pieces of 19th century scrimshaw are considered to be valuable collectibles today. Reference: McNamara, Robert.

The Wreck of Hope (Long-nosed Common Dolphin skeleton, Delphinus delphis) featured as part of the exhibition Anatomy Lessons, shown at the National Wool Museum in 2024. The exhibition featured meticulously-sculpted, life size skeletons, making visitors question their place in this web of the living and the dead. From a towering giraffe stretching 4.4 metres in height, to an army of over 50 delicately rendered frogs, this exhibition was enthralling in scale. Each sculpture is an accurate portrayal of a real animal and is carefully measured, drawn, and moulded from steel, wire, and foam. The frame is then intricately knitted over to create these thought-provoking pieces. Each sculpture tells a story, one of the collection of animals by museums and collectors, of Western safari hunters, of human encroachment, and of the often-sad role of the animals in our lives. These underlying concepts are explored and reflected by the materials used. Wool, that speaks of warmth, of comfort, of care, meets the size, grace, and sheer breathtaking beauty of the pieces, clashing with the hard and complex stories beneath. This knitted dolphin skeleton was the start of Beevor's interest in comparative anatomy. Beevors recalls viewing a dolphin, one of many skeletons alongside a mouse and a lion in the Australian Museum's collection during a school visit in the 1970s. At the time, school children watched TV reruns of 'Flipper', which portrayed dolphins as intelligent and noble animals. Elsewhere, the conservation movement was growing, and appeals to protect marine mammals were gaining momentum through the 'Save the Whales' campaign. The fascination with live dolphin shows had grown throughout the 1960s and 1970s and the ethics began to be questioned. Some believe they played an important role in raising public awareness of cetaceans and their welfare. Others argued the performances glorified the dominance of heroic trainers over the subordinate dolphin, and offered little education about the dolphins' natural characteristics nor prioritised their welfare. Many of these facilities are now closed and all dolphin species are protected by international accords aimed at conserving wild populations. Despite this dolphins are still at risk of swallowing plastic waste, mercury toxicity, toxoplasmosis, boat impacts and being bycatch in commercial fishing operations. Originally from Australia, Michele Beevors has been practicing in New Zealand for the last 20 years. She is Head of Sculpture at Dunedin School of Art, Otago Polytechnic, New Zealand’s oldest, and one of its most prestigious, art schools. Beevors has exhibited in galleries, museums, and exhibition spaces in across New Zealand, Australia and Vienna with art that is defiant, unconventional, and moving.Life sized knitted skeleton of a dolphin, with white wool and internal steel, foam and wire frame.
