Researchers have discovered the world's oldest European hedgehog in Denmark.
- The animal -- which was found by the Danish Hedgehog Project -- has been confirmed to be 16 years old, which is seven years older than the previous record holder, according to lead researcher Dr. Sophie Lund Rasmussen. The two runners-up are 13 years old and 11 years old, respectively, Rasmussen says. Most hedgehogs live an average of two years, researchers say.
- In recent years, the number of European hedgehogs living in urban environments has dropped by 30 percent, while the number living in rural areas has fallen by 50 percent, researchers say.
