They'd have to consume a lot of squid to maintain their lifestyle." "The whale is not getting much by eating it. "Because the squid is more cold-blooded than we thought, they are not really that nutritious," Rosa said. Rather than swimming after prey, the colossal squid would wait to ambush passing fish.Īnd if the colossal squid consumed and expended less energy than previous thought, as this data indicates, then biologists will also need to reevaluate the squid's role as whale food, Rosa said.
"It's a squid that weights half a ton with hooks in its tentacles, but our findings show it’s more like just a big blob."Ĭontrary to the image of Kraken-like shellfish attacking ships and dragging sailors to their deaths, this new data paints a picture of a mostly sedentary creature, Rosa said. "Everyone thought it was an aggressive predator, but the data suggests otherwise," Rosa told LiveScience. They found, the squid would've had a slower metabolism and so moved slower than expected, waiting for prey, rather than running it down. (The so-called giant squid belongs to the genus Architeuthis, a different group of animals from the colossal squid.) Rosa and Seibel looked at the relationship between metabolism (how the body's cells turn food into energy) and body size for smaller squids in the same family and used the information to predict the metabolism of the colossal squid ( Mesonychoteuthis hamiltoni). This new view of the colossal squid comes from data analysis made by marine biologists Rui Rosa, of the University of Lisboa, Portugal, and Brad Seibel, of the University of Rhode Island. This finding not only upends science's understanding of the squid itself, but forces a reevaluation of its role in the entire ecosystem where it lives some 3,000 to 6,000 feet (914 to 1,830 meters) beneath the Antarctic sea. However, new research suggests the enormous sea creature may not be the fierce hunter of legend. He also said he wasn’t surprised that the squid was found in Japan, because the Sea of Japan, a relatively narrow body of water between the western coast of Japan, part of Russia, and North and South Korea acts as a natural trap, particularly during the winter.Measuring longer than a school bus and sporting tentacles covered in razor-sharp hooks, the colossal squid is the stuff of nightmares. A typical giant squid may live one to two years, and the maximum is three to four years. Vecchione told Snopes that giant squids don’t have a very long life in relation to humans. Smithsonian biologist Mike Vecchione, who specializes in cephalopods, told us in a phone interview that it appeared in a second video posted by the aquarium that the squid was breathing - but that it was probably near death.
The squid was real, but didn’t appear to be in good health. Giant squid sightings are somewhat unusual, so the video created a lot of excitement. In late January 2021, the Aquas Aquarium in Shimane prefecture in southern Japan posted a video on Twitter showing a giant squid that was found washed up in the city of Izumo.
