The sperm whale skull amphitheatre cradles an enormous two-tonne spermaceti organ. The amphitheatre separates this organ from the cranium and the cervical vertebrae that lie in close proximity to the base of the skull. Here, we elucidate that this skull amphitheatre is an elastic, flexible, triple-layered structure with mechanical properties.

The sperm whale skull amphitheatre is found to be a sandwich composite structure. • Histology of the bone reveals the predominating layers have a substantial woven component. • The middle layer is macroporous but contains larger quantities of primary bone. • Nanoindentation reveals a stiffness of ca. 13 GPa in each layer. •

Along with the suspended skeletons, the Museum also displays the skull of a humpback whale (Megaptera novaeangliae) and the huge lower jaw of a sperm whale (Physeter macrocephalus). This jaw belonged to an animal '88-foot long', which far exceeds the known maximum size of the species today, suggesting that sperm whales may have been.

2. Sperm whale clans. The foundation of sperm whale society is the matrilineally based social unit of ten or so females and their offspring. The members of the unit travel together, suckle each others' infants, and babysit them while mothers make long deep dives to feed [14,15].They also defend themselves communally against their only serious natural predator, the killer whale (Orcinus orca) [].

The sperm whale's skull accounts for perhaps 12 percent of the weight of the head. The other 88 percent consists mainly of a peculiar anatomical feature located in the whale's snout above the upper jaw: the spermaceti organ. The organ is a complex mass of muscle and oil-filled connective tissue. The oil is what gave the sperm whale its name; in a
