Maybe a little something added:
Scientists don’t know for sure why the orcas are targeting vessels, but they have urged onlookers to
to the creatures, and especially to refrain from framing their actions as retaliation, reports the
’s Dino Grandoni.
“We believe this narrative inappropriately projects human motivations onto these whales, and we are concerned that perpetuating it will lead to punitive responses by mariners or managers,” a group of 35 scientists wrote in an
this August.
Orcas are highly social animals, and in the past, they have periodically adopted short-lived fads, such as wearing
on their heads like hats. While the vessel strikes are persisting longer than a typical fad, they might disappear just as quickly as they began, the scientists wrote. But overall, it appears unlikely the creatures are behaving maliciously or seeking revenge on humans.
“I just don’t really see it as an agonistic activity,” said
, a marine biologist at the University of Washington and director of the conservation research organization Wild Orca, to the
’ Susanne Rust earlier this year.
So far, the behavior has mostly been isolated to the group inhabiting the waters off the Iberian peninsula—though, this summer,
did occur more than 2,000 miles away near Scotland.
One theory scientists have for the behavior is that orcas are simply having fun—they see boat rudders, then use their noses to push them until they snap.
“They’re pushing, pushing, pushing—boom! It’s a game,”
, a scientist who leads the marine research group Conservation, Information and Research on Cetaceans (CIRCE), told
’s Sophie Hardach in June. “Imagine a kid of 6, 7 years, with a weight of three tonnes. That’s it, nothing less, nothing more. If they wanted to wreck the boat, they would break it in ten minutes’ time.”
Another theory is that a female orca within the group named White Gladis may be acting out because of a past traumatic run-in with a vessel. Perhaps, then, the behavior is catching on among juveniles, because they “look up to these very important females in the pod,” in orcas’
, as
, a biologist at the University of Aveiro in Portugal and a member of the Atlantic Orca Working Group, said to
’s Jacopo Prisco in June.
Still, some scientists point out that we, as humans, cannot presume to know the orcas’ motivation. And any attempts to guess are just that: guesswork.
“Nobody knows why this is happening,”
, director of marine mammal research at the University of British Columbia in Canada, told
earlier this year. “My idea, or what anyone would give you, is informed speculation. It is a total mystery, unprecedented.”
