killer whales Scientists announced on Monday that the video of seaweed pieces to rub and groom each other was caught on the video, stating that sea mammals are the first proof of making their own equipment.
Man is far from being the only member of the animal empire, which has mastered using equipment. The chimpanzee fashion is affixed to the fish for termites, the crows made twigs bent to catch the grubs and catches the elephants with branches.
The use of tools in the world’s hard-to-study oceans is rare, although marine udilab is known to break the open shellfish with rocks, while octopus can exclude mobile houses from coconut shells.
A study published in Journal current biology The severely disappearance of the orcas describes a new example of the use of tool by the population.
Scientists are monitoring the killer whale, for over 50 years, between the British Columbia and Canadian province of the Canadian province of the state of Washington.
Rachel John, a master student of a master at the University of Exeter in UK, said at a press conference that he first saw “something strange”, while last year watching the drone camera footage.
Researchers went back to old footage and were surprised to find this behavior, documenting 30 examples in eight days.
A whale bull will use its teeth to break a piece of kelp, which is strong but flexible like a garden hose.
The Calp will then be put between her body and the body of the other whale, and they will rub it between them for several minutes.
The pair creates a “S” shape to keep the seaweed between their bodies as they roll around.
“Skin maintenance behavior”
The whale is already known to be trapped through marine algae in a practice called “kelping”.
They are considered partly to do so for fun, partially using seaweed to rub their body to remove dead skin.
The international team of researchers called the new behavior “alochaelping”, which means keeling with another whale.
Researchers wrote, “We hypothesize that allkelping is similar to skin maintenance behavior displayed by other cetaceans.”
They found that the killer whales with more dead skin were more likely to engage in the activity, warning that it was a small sample size.
The whale was also added to family members or other people of the same age, suggesting that there is a social element of activity.
Scientists said that this was the first known example of creating a device.
Janet Mann, a biologist at the University of Georgetown, did not include the research, praised the research, but said it “went far away” in some of its claims.
He told AFP that botalenose dolphins that can use Marine Sponze to hunt can also be considered a manufacturing tool.
And it can be argued that other whales are known to use bubble mks or use tools to use the tool to use mud plums, used to benefit many individuals, claimed in another paper, one and the first, Mann said.
Although, The author of the study says ALLOKELPING “can be the first case of non-human animals that manipulates a device with their body’s origin rather than an appendage.”
Michael Weiss, the research director of the Center for Whale Research and the prominent writer of the study, said it is the latest example of socially learned behavior among animals that can be considered “culture”.
But the number of killer whales, the southern resident, has decreased to only 73, which means that we may soon lose this unique cultural tradition, warned.
“If they disappear, we are never meeting any of them,” he said.
Whales eat mainly chinook salmon, which has fallen due to more, climate change, housing destruction and other forms of human intervention.
Orcas and salmon are not alone – the undersete Calp forests have also been destroyed as sea temperature increases.
Until something changes, the approach to the southern resident killer whale is “very tarnished,” Weiss warned.
Earlier this year, an unusual spectacle that also had a pod of orkas. Caught on video When the audience in Seattle was treated with the rare vision of APEX poachers Hunt a bird Close to the edge.
