Fish ‘are scared of their own reflections’

Fish are scared of their own reflection and try to fight themselves when they look at a mirror, a new study has revealed.

They become even more frightened when they see their reflection making the same moves as them and appearing to fight back, found researchers.
Scientists believe the research indicates that the brains of fish are surprisingly similar to those of humans.

In both cases the fish tried to fight the ‘other’ fish, resulting in 20-minute long ‘sparring’ sessions.
Afterwards, the scientists tested blood samples for testosterone and other aggression-inducing hormones. All the fish showed high levels of testosterone.
The fishes’ brains were also examined but only those that fought with their reflection showed high activity in the amygdala, the brain region crucial to fear.
