Physical Properties of Spermaceti Oil in the Sperm Whale
As a basis for an understanding of the buoyancy function ofthe spermaceti organ of the sperm whale (Physeter macrocephalus L.) this paper deals with the following three physical properties of spermaceti oil: (i) the relationship between its density, temperature and pressure; (ii) heat exchange during freezing and melting; and (iii) the elevation of its temperature during increase in pressure. 19
متن کاملDIVEBOT: A diving robot with a whale-like buoyancy mechanism
Sperm whales feed primarily on squid and often have to find their food at depths between 1000 and 2000 meters. To do this they require sophisticated buoyancy regulation. It has been known for some time that they achieve long-term buoyancy regulation by altering the temperature of their spermaceti organ, located in the enlarged snout. In a large male this organ may contain four tons of spermacet...
متن کاملThe face that sank the Essex: potential function of the spermaceti organ in aggression.
'Forehead to forehead I meet thee, this third time, Moby Dick!' [Ahab (Melville, 1851)] Herman Melville's fictional portrayal of the sinking of the Pequod was inspired by instances in which large sperm whales sank whaling ships by ramming the ships with their heads. Observations of aggression in species of the four major clades of cetacean and the artiodactyl outgroup suggest that head-butting ...
متن کاملArchitecture of the sperm whale forehead facilitates ramming combat.
Herman Melville's novel Moby Dick was inspired by historical instances in which large sperm whales (Physeter macrocephalus L.) sank 19th century whaling ships by ramming them with their foreheads. The immense forehead of sperm whales is possibly the largest, and one of the strangest, anatomical structures in the animal kingdom. It contains two large oil-filled compartments, known as the "sperma...
متن کاملRelationship between sperm whale (Physeter macrocephalus) click structure and size derived from videocamera images of a depredating whale (sperm whale prey acquisition).
Sperm whales have learned to depredate black cod (Anoplopoma fimbria) from longline deployments in the Gulf of Alaska. On May 31, 2006, simultaneous acoustic and visual recordings were made of a depredation attempt by a sperm whale at 108 m depth. Because the whale was oriented perpendicularly to the camera as it contacted the longline at a known distance from the camera, the distance from the ...
