Rare Photos: Giant Squid Eaten by Sperm Whale

Saving It for Later?

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.

A Whale of a Party

A female sperm whale, carrying a piece of giant squid in her mouth, leads a gargantuan dinner party in the northwestern Pacific on October 15, 2009. Sperm whales are voracious hunters of squid—the species as a whole consumes an estimated 110 million tons a year.

Aiding the sperm whale in its hunts is the world's largest brain, which is surrounded by patches of spermaceti. Once used in candles and ointments, the white, waxy substance was long ago mistaken for the whale's sperm, leading to the species' curious name.

Letting Go

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.

A Deep-Sea Arm

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."
