Original title: surprise discovery! Dolphins are also divided into left-handed and right-handed
As we all know, humans can be divided into 'left-handed' and 'right-handed'. Miraculously, this situation also exists in the animal world. According to the Russian satellite network, a new study in the journal open science of the Royal Society shows that dolphins, like humans, can also be divided into 'left-handed' and 'right-handed', and they will obviously show this preference when foraging.
The study also showed that among the 27 dolphins surveyed, only one dolphin was' left-handed '.
Scientists say this shows that the left hemisphere of the dolphin brain has a special area responsible for processing the information seen by the right eye.
Dolphins generally adopt a unique method when foraging, which is called 'crater foraging', that is, when foraging, they swim slowly along the seabed, and once they find prey, they quickly turn to catch it.
According to the research between 2012 and 2018, scientists found that dolphins prefer to turn right when foraging. Among the 27 dolphins surveyed, they turned 709 times, of which 705 (99.4%) turned right.
