Sperm whales eat big squids - and squids fight back by grabbing hold of the whale. When sperm whales and squid do tangle, though, it's probably less "battle of the ocean giants" and more a spar for survival, Vecchione says. Sperm Whale and Giant Squid, from the AMNH's Hall of Ocean Life. That's still remarkably large and places the creatures at around the same size as an adult sperm whale, as seen in the famous display in the AMNH. In reality, giant squids probably top out at around 30 or 40 feet, Vecchione reasons. ![]() "And then it grew up - and as it grew, the scars grew as well." ![]() In those cases, Vecchione says "almost certainly what's happened is that that was a sperm whale that had an interaction with a giant squid when it was a fairly young sperm whale. Reports of 100-foot-long squids, for instance, have been based on calculations from sucker marks left on sperm whales. Vecchione was not involved in the study.Īs a result, some of the estimates of giant squids' top size may be exaggerated. But a scar left on an animal can change over time as the animal gets bigger, explains Mike Vecchione, zoologist and curator of Cephalopoda at the Smithsonian National Museum of Natural History. Researchers have further questions about the maybe-interaction with the white-tipped shark.įor instance, the team estimated the size of the squid based on how large they believe the sucker marks were. Still, what we don't know about giant squids can be measured in sinking leagues. He reasons that they are "probably not that rare" - otherwise, what would sperm whales be feeding on? Unlike sperm whales - which, at 40 feet long, are pretty hard to miss - giant squids are notoriously elusive. Giant squids might also be more common than we think, Siddal says. But a lot of what we know comes from either partial squids washed ashore or the mashed-up contents of a sperm whale's stomach, AMNH curator Mark Siddall explains. In the intervening centuries, around 20 different species of Architeuthis have been identified. The lore extends even further back, through the 1500s, report curators from the American Museum of Natural History (AMNH). Mysterious squid of the deep - The first time humans scientifically described the giant squid, Architeuthis dux, was in a paper published in 1857. There are a few families of larger cephalopods living near Hawaii that could have been the culprit. This is the first time he's seen these kinds of markings on a shark.īased on the size of the tentacle marks, Papastamatiou and his colleagues think that the cephalopod that left the marks was at least 1.5 meters long - not including its tentacles. Papastamatiou, an assistant professor at Florida International University, studies predator ecology in locations around the world - near Mexico, French Polynesia, and Belize. "He has seen so many that I think he knows it when he sees something different." " spent probably more time in the water with those sharks, off of Kona, than anybody else," the study's lead author Yannis Papastamatiou tells Inverse. Subsequently, a team of scientists used Verbeck's photos from the past decade to inform the new finding. The photo is the first evidence of marks from a cephalopod on a shark. ![]() Whitetip shark with sucker marks that appear to be from a cephalopod. In recognition of the 45th anniversary of the release of Jaws, Inverse is sharing weird-but-true stories about sharks. A closer look suggested they were sucker marks. Once he got home and looked over his photos, he noticed that those white dots were evident in the last photo he'd taken that day. Verbeck, an underwater photographer whose unique style involves only shooting in ambient light while holding his breath, was "perplexed by the seemingly purposeful placement of them," he tells Inverse. He was shooting photos off the coast of Kona, Hawaii when he spotted the strange markings. This finding was published in June in the Journal of Fish Biology.īefore November 2019, study co-author Deron Verbeck had never seen anything like the “white dots” he would later notice on an oceanic whitetip shark. The shark survived, though not unscathed. Now, for the first time, scientists have evidence of a large cephalopod tangling with a shark. To fill in the gap, humans have spent centuries spinning tales of hundred-foot, tentacled monsters, fierce enough to capsize boats and fend off sharks. Deep in the ocean, there is a profound space between what science can explain and what's left to our imaginations.
