Kyoto Aquarium and the Sumida Aquarium in Tokyo keep high-resolution maps that track the Penguins serious crushes and heartbreaks but also adultery and egg-stealing. Now this would make for an interesting reality show!

Penguins, the way they waddle around and protect their eggs, are often thought of as cute, cuddly and romantic. But those who observe them for extended periods know they have a dark side. Two aquariums in Japan, Kyoto Aquarium and Sumida Aquarium, keep obsessive tabs on their penguins and maintain an updated flowchart that visualizes all their penguin drama.

As Kyoto-based researcher Oliver Jia points out, penguin drama can include serious crushes and heartbreaks but also adultery and egg-stealing. And these Japanese aquariums have it all charted in a flowchart that can be studied for hours.
