See fish using food picker tool

For the first time, scientists took a series of images of the black-spotted fishing fish, scientifically named Choerodon schoenleinii , using tools to pick up meat in a son's shell.

According to the American Association for the Advancement of Science (AAAS) magazine, while exploring the world's largest coral reef, Great Barrier (Australia), professional diver Scott Gardner heard the sound of a crackling crack. and swim to see what happened.

The 'noise maker' is just a black-spotted fish, but what surprised Gardner was that he knew how to use a mouth to suck a son and slam it down on a rock - the tool needed to break the shell. Before long, the son's shell cracks and the fish cleverly separates the shell, eats the meat inside and swims away.

There's a camera in hand, photographer Gardner takes the opportunity to record everything that's happening and it seems these are the first photos of wild fish that use tools.

Previously, scientists thought that it seemed that only humans could use intelligence to use tools. However, in recent decades, they have also discovered that some animals are capable of doing this. For example, capuchin monkeys know to put fruits, nuts or nuts on hard rocks and use heavy objects like rocks to smash them; or crows in Tan Dao area, Oceania know how to use the mouths of small branches to pry into tree holes - insect hideouts, so that insects bite into the branches and the crow just pulls out the prey and 're-eat'.

Among animals that know how to use tools to get food, there are dolphins, elephants, mole in Africa and even octopus.

Dr. Culum Brown - an animal behavioral ecologist, one of the authors of this study, worked at Macquarie University (Australia) - commented on Coral Reefs: ' Photographs (by photographer) Gardner is a great proof that fish are very intelligent. Obviously, the black-spotted fish have carried out the behavior in a sophisticated and regular manner during their life, because we see many other shells lying around the hard rock floor . '

' Using the tool is especially difficult for animals that don't have chi living in the water, but the black spotted fish found an ingenious solution. The fish holds the son in his mouth and constantly swings his head to the left or the right fiercely, at the same time smashing the boy on the stone floor until the shell of the shell cracks . We really need to spend a lot of time filming Underwater to learn more about the use of tools in marine fish '- Mr. Brown added.
