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.

Penguins are highly social species. They like being with others and, like humans, this can often lead to polyamorous and sometimes scandalous situations. Penguin drama can include serious crushes and heartbreaks but also adultery and egg-stealing. Penguins may even develop crushes on their caretakers. And these Japanese aquariums have it all charted in a flowchart that can be studied for hours.
