Cassius, the largest living crocodile in captivity, could be even bigger than previously thought.

The saltwater crocodile — who is thought to be 120 years old — entered the record books in 2011, when he measured nearly 18 feet (5.48 meters) long. But his keepers haven't measured him since, meaning Cassius may have grown even bigger since then.
