It's a pretty easy life when you are top of the food chain, right? Maybe not always.

Researchers who caught and tagged a 12-foot, 9-inch, 1,164-pound great white shark on Oct. 4 off Nova Scotia found teeth marks on its jaw and head.

One of the wounds was old and healed while the other appears to have happened recently.

Scientists believe the male shark was either bitten by a larger male while competing for a female or by a female who was not interested in mating.

Researchers with Ocearch named the big fish "Vimy" and tagged him with a tracker.
