"It's Me!"
In the latest finding about wildlife cognitive ability, Japanese researchers say they have found that a common fish can recognize itself in photos.
A team from Osaka Metropolitan University writes in the journal Proceedings of the National Academy of Sciences that the Labroides dimidiatus, commonly known as a cleaner fish, demonstrated the ability, but only when it could see its face and not just its body. The species had already been proven to recognize itself in mirrors. “This study is the first to demonstrate that fish have an internal sense of self,” concluded study lead author Masanori Kohda.
