Great White Breaks Distance, Speed Records for Sharks

A female great white shark has completed the first documented round-trip ocean crossing by a shark, swimming farther than any other known shark, according to a new study.

Nicole, as the shark is being called, traveled from Africa to Australia and back-a total of 12,400 miles (more than 20,000 kilometers)-in nine months. The feat also set a second record: fastest return migration of any known marine animal.
