Zebrafish are Hopelessly Obsessed with Robotic Clones of Themselves

Zebrafish would rather hang out with other zebrafish than with anything else, even if that means looking at robotic replicas of themselves.

A team of researchers at NYU Tandon School of Engineering, funded by the National Science Foundation, printed 3D robotic models of zebrafish to study how real zebrafish would react to the robots in comparison to other living organisms. The models not only looked like actual zebrafish, but were designed to move like them, too.
