Orcs do not stop surprising us. We already knew that, like other animals, their heads, fins and bodies with seaweed, to eliminate parasites and preserve the skin of a healthy one. But now the study published in the journal Current biology Shows for the first time that “Manufacturing tools” With these sea elements To care for yourself each other. We can say that they have a beauty routine.
While watching some Images recorded by drones In Salish -More, the wound ecologist Michael Weiss discovered that one of the orcs wore something green in his mouth, which he used to rub with another.
What he had was the end of a stem of algae, which bit a piece and placed it between him and another orca to clean and scratch between them. Act of help and cooperation, which can last up to 15 minutes. This is what was called Allkelping; Unknown behavior can still be before and after in the study of animal behavior.
Theories about “Allocklping”
“Find out that the whales not only used“ tools ”, but also produced them, and that they were never used before to see the marine mammals, it was incredibly exciting,” Vaiss said from the United States Cutian Research Center.
He and his team believe that there are two reasons behind Allkelping:
- The first can be HygieneSince the whaling are separated from dead skin, they get smooth and aerodynamic bodies.
- The second can be Strengthening social tiesSince the pairs of whales that showed this behavior were close relatives or a similar age.
According to experts, the orcs are curious and smart, with a large brain and parts of this highly developed organ. Each population of Orcas even Your own dialectAnd some, such as those that fill the Valdes Peninsula in Argentina, hunting behavior studied from generation to generation, consisting of a voluntary one on the beach, then to bring all its strength to the return to the open sea.
Also in other species
Nevertheless, the orcs are not the only whaling, known for the use of “tools”. Some were noticed Dolphin’s nose bottle To resign and carefully using lips to scare away your prey on the seabed. Others use their tails to get to the ground in a circle and create mud columns that catch fish. A Humpbacked whales For a long time they used bubble networks to catch their prey.
This is a behavior associated with the search for food, but what does Allkelping They are their possible advantages for the skin and relationships. In other words: it seems Cultural practice. A practice that would not have been discovered without the achievement of the technology of drones and chambers, which offers an air view that marine animals are made just below the surface of the water.
