PostSubject: Giant Squid Eaten by Sperm Whale   Thu Nov 05, 2009 6:35 pm


Carrying the remains of a roughly 30-foot (9-meter) giant squid in her jaws, a female sperm whale, with a calf at her side, swims near the surface off Japan's Bonin Islands (map)in the northwestern Pacific. Taken on October 15, this and other "absolutely sensational" new pictures offer rare proof of the sperm whale's taste for giant squid, said giant squid expert Steve O'Shea of the Auckland University of Technology in New Zealand.

The pictures may also reveal that adult sperm whales, which grow up to 59 feet (18 meters) long, use pieces of their prizes to teach youngsters how to catch their own, O'Shea told National Geographic News.

The group of five adults and one calf kept diving deep in unison, photographer Tony Wu told the Daily Mail. "It seemed as if the adult whales were trying to teach the baby to dive and also to eat squid," he said.


Eating on the run, a female sperm whale carries the remains of a giant squid off the Bonin Islands, about 621 miles (1,000 kilometers) south of Tokyo, on October 15, 2009.

The whale almost certainly carried the giant morsel up from the dark depths of the nearby Osagawara Trench, a favorite hunting ground of sperm whales. The whales routinely dive for an hour or more to depths of up to 3,280 feet (1,000 meters) in pursuit of giant squid, which are thought to rarely venture higher than 1,000 feet (300 meters) below sea level.

Battles between giant squid and sperm whales often leave the whales scarred with sucker marks. Until recently, such wounds--along with analysis of sperm whale stomach contents--were the only proof of the whales' appetite for giant squid.




Part of a sperm whale's catch--a giant squid--drifts free in one of the rare pictures captured in the Pacific on October 15, 2009.

The whale at right was also photographed carrying the giant morsel in her mouth--rare evidence of the whales' taste for giant squid, which some researchers say can grow to 43 feet (13 meters) long and weigh more than 600 pounds (272 kilograms).

The whales use sophisticated echolocation--similar to sonar--to find their quarry in the pitch blackness of the deep.


An 11.5-foot-long (3.5-meter-long) leftover, this giant squid arm was recovered at the surface from another sperm whale hunt on October 14, 2009, in the same place as feeding frenzy photographed underwater the next day.

At this site in 2006, a Japanese expedition had captured the first ever images of a live giant squid.

During the rare October 15 photo shoot, photographer Tony Wu was "absolutely ecstatic," he told National Geographic News. "But completely focused on making sure I got photos."
