A king penguin has been observed trying to adopt the baby of its mortal enemy.

The adult penguin kidnapped a skua chick on Marion Island, in the sub-Antarctic, then attempted to raise it.

During the incident, reported in Polar Biology, the penguin vigorously defended the chick and tried to brood it upon its feet.

Penguins often try to raise chicks that aren't their own, but it's surprising for one to try raise the young of its natural predator, say scientists.
