Looking at themselves in a mirror is enough to scare some fish, a new study finds.
Fish looking at a mirror showed increased brain activity in regions linked to fear than fish faced with an actual fish separated by glass, the study showed. However, in both instances the fish responded the same physically, engaging in a routine of combative gestures to try to fight the other fish – be it a reflection or an actual opponent.
"It seems like something they don't understand," said Julie Desjardins, researcher and post-doctoral biologist at Stanford University. "I think this stimulus is just so far outside their realm of experience that it results in this somewhat emotional response.
