Life is not easy when you are a two-headed tortoise!
Just ask Janus, the world's oldest two-headed tortoise. She celebrated her 25th birthday at Geneva's natural history museum in Switzerland. She is one of the most unusual attractions there.
Janus is named after the two-faced Roman god from mythology. She also has two hearts, two stomachs and four lungs. She munched on edible flowers and lettuce leaves to mark her birthday.
Janus would not have survived long in the wild, says museum director Arnaud Maeder.
Why not? Because she cannot pull her two heads back into her shell, so she would have been easy prey for predators.
