For Komodo dragons, there’s no place like home

Komodo dragons, the prehistoric-looking lizards that can grow up to 3 meters in length and weigh more than 140 kilograms, have no problem traversing their island surroundings. But more often than not, they choose to stay close to home, The New York Times reports. Researchers observed 10 populations on four Indonesian islands over a 10-year period and found that the lizards never left the area where they were born, they report today in the Proceedings of the Royal Society B. When the scientists transported several Komodo dragons kilometers away from their homes, they all eventually found their way back, even swimming between islands. The researchers suspect staying close to home might offer some survival benefits, including familiar territory and easy access to food and mates.
