Indo-Pacific bottlenose dolphins in Shark Bay are a rare way to get food in Western Australia.
They cover the fish in the shell of a large, empty sea snail. Then they take the bowl and bring the fish to the surface and shake it upside down. Silver! Get the fish straight into the dolphin’s belly.
It’s called shelling, the only other device that is used is documentation of the dolphins – and the first is that the dolphins were just seen by their friends learning.
“This is an important milestone,” said Michael Kurtzen, evolutionary biologist at the University of Zurich in Switzerland.
Dolphins (Torsip adonix) were seen 20 years ago before using tools and shoved sea sponges on their beaks to protect them. You were protected. This behavior is called the sphincter and gives dolphins access to food in deeper water channels than dolphins that don’t go deeper.
Spelling is done on subway lines, a skill passed from mother to daughter.
But there is also another type of learning, the horizontal social transition, in which individuals learn from their peers. This is more evident in the genre with large cultural reserves.
There are similarities between dolphin and ape societies, which has led scientists to believe that dolphins must be able to learn horizontally.
Previous studies on whether dolphins can learn from their friends have been promising but unsuccessful. Now a team of researchers led by Sonja Wilde, a behavioral environmentalist at the University of Konstanz in Germany, has finally identified it.
Their numbers correspond to the observations of a decade. Between 2007 and 2018, researchers documented more than 1,000 individual dolphins in approximately 5,300 animal encounters.
In these competitions, bombardment behavior was observed in 19 people with 3 different genetic variants on 42 different occasions.
This is a relatively small number compared to the total number of competitions, but it was enough to analyze how this behavior was learned.
They used genetic, behavioral and environmental data to investigate possible transmission routes and found that the shelling spreads to friends rather than parents.
