Fisherman captures shark viciously attacking another shark

These fishermen weren't the only ones looking for their next catch.

Peter Hinck captured amazing footage of a shark attack from his paddleboard near Hutchinson Island in Florida.

Hinck's friend caught a 4-foot-long black tip shark and intended to release it. As he was reeling in his catch, a large bull shark attacked and bit the black tip shark in half. Hinck was able to film two sharks finishing their attack.
