Arnbom, Tom Arne Individual photographic identification : a key to the social organization of sperm whales. Masters thesis, Memorial University of Newfoundland. Sperm whales were tracked visually and acoustically in the waters west of the Galapagos between February and April
On the swells of the Sea of Cortez, everything looks like a whale. Lulled by disappointment, the rocking boat and general monotony, I drift into torpor. Then, less than half a mile away, a series of unmistakable spouts erupts, and bursts of exhalation carry across the water.
The inspiration for the white whale of Moby Dick, sperm whales have the largest heads, biggest brains, and make the loudest sound of any animal on Earth. Region: Arctic. Destinations: Lofoten, Greenland, Svalbard, Iceland.
Sperm whale foraging behavior changes in response to anthropogenic sound. Understanding cetacean behavioral reactions to anthropogenic sound is critical for designing appropriate management strategies to predict and mitigate adverse behavioural responses to noise. Foraging behavior is of particular interest, since energetic balance is closely linked to fitness and reproductive success. In order to quantify changes in sperm whale echolocation-based foraging behavior in response to sound, we studied sperm whales equipped with DTAGs, multi-sensor tags that record sound as well as dive depth and movements.
Far west of the Galapagos Islands in the Pacific Ocean. A whaleship pursues a pod of sperm whales. Suddenly, an eighty-five foot long giant charges the ship, ramming it with its head not once, but twice, caving in the bows and sending the ship to a watery grave.

Sperm whaling is the hunting of these marine mammals for the oil, meat and bone that can be extracted from their bodies. Sperm whalesa large and deep-diving species, produce a waxy substance that was especially useful during the Industrial Revolutionand so they were targeted in 19th-century whalingas exemplified in Moby Dick. Sperm oil is no longer needed, but another unusual product, ambergrisis still valued as a perfume fixative.
