Research groups such as Professor Masanori Koda of the Graduate School of Science, Osaka City University and the Max Planck Institute in Germany have found that there are fish that can recognize their appearance in the mirror.It is a discovery that overturns the conventional wisdom that fish have low memory and cognitive ability in Honsome Wakebera, which lives in the tropical and subtropical waters of the Pacific Ocean and the Indian Ocean and exterminates parasites from the bodies of other fish.

 According to Osaka City University, when he showed himself in the mirror on Honsome Wake Bella in a water tank, he first recognized it as another fish of the same type and repeated actions that seemed to be an attack, but eventually he realized that he was himself. Recognizing and stopping the attack, he began to look at himself frequently in front of the mirror.
In the case of chimpanzees, it is because they are self-aware that they often see them in the mirror, and the research group believes that Honsome Wakebera is self-aware at this stage.

 In addition, when he made a mark similar to a parasite on the throat that he could not see, he noticed the mark and showed a movement like rubbing the throat on sand or stone to remove the parasite.When I took the mark, I showed a gesture to confirm the throat.

 The ability to recognize yourself in the mirror has been discovered in animals with a high degree of social life, such as chimpanzees, dolphins, elephants, and crows, but this is the first time that it has been confirmed in fish.The research group believes that "it suggests that fish also have a high degree of intelligence and insight, such as self-awareness."
