There’s just a 1 in 3,700,000 chance a person will likely be killed by the use of a shark in their lifetime, on the other hand the fear is still enough to have swimmers worrying about being perceived as prey. Now, new research is helping the long-standing thought that after great whites do cross in for a piece, it’s a case of “mistaken identity.”
A gaggle of biologists from the UK and Australia compared footage of seals swimming with motion pictures of other people swimming (with and without paddle surfboards). They then edited the clips to simulate a perfect white’s vision—the sharks are almost certainly colorblind, and they can’t make out implausible component—and situated that from the ocean inhabitant’s standpoint, other people do no doubt go through an impressive resemblance to seals. The findings were revealed the previous day inside the Mag of the Royal Society Interface.
“Great white sharks are often portrayed as ‘mindless killers’ and ‘fond of human flesh.’ However, this does not seem to be the case, we just look like their food,” Laura Ryan, a neurobiologist at Macquarie Faculty in Australia and lead author of the learn about, suggested Are living Science.
Regardless of their less-than-stellar vision and subpar spatial trust, great white sharks are extraordinarily visual creatures, and rely on motion and shadows when searching for prey. To actually see throughout the species’s eyes, the research crew had to get ingenious.

“We attached a GoPro to an underwater scooter, and set it to travel at a typical cruising speed for predatory sharks,” Ryan said in a commentary. The researchers then paired the recordings with laptop models to simulate how identical other people look from a shark’s distorted view underneath the outdoor. The results showed a dangling closeness to seals and other pinnipeds, supporting the “mistaken identity” thought.
“I knew there would be some similarities, but maybe not to the extent we found,” Ryan suggested Are living Science. “Specifically, I thought swimmers might not be as similar as a surfer to a seal as they typically aren’t involved in as many shark bites. However, the swimmers were also difficult to tell apart from a seal.”
Shark attacks may be scary and dangerous, on the other hand they are relatively unusual. In 2020, there were 57 confirmed unprovoked instances global, in step with the Faculty of Florida’s World Shark Attack Document; of those, 10 were fatal. The 2015 to 2019 average was once as soon as 80 incidents consistent with one year.
“They eat seals everyday and bites on people are incredibly rare,” Catherine Macdonald, a marine scientist at the Faculty of Miami now not involved inside the learn about, suggested the New York Events. “So if they’re not solving the problem visually, then how do we think they’re solving it?” To hit the best goals, shark may well be relying on other senses, like scent. If that’s the case, additional analysis on how great whites take advantage of those senses would possibly have the same opinion resolve interventions to forestall further attacks.
As Ryan put it in a commentary: “Understanding why shark bites occur can help us find ways to prevent them, while keeping both humans and sharks safer.”
