Monster shark rises from deep to chomp another shark

This is the incredible moment a boat full of anglers watched in horror as a monster shark rose from the deep to chomp the tail of another shark which they were trying to reel in.

The remarkable clip, which was filmed off the coast of Miami, Florida in April, shows a female angler reeling in a bull shark when suddenly the much larger shark lurches into view and bites off the entire tail of the hooked fish.

Amazingly, the hooked shark continues to thrash about with no tail even as other sharks start to circle the bloody water.

The incident came as a huge shock to the fishing party who were attempting to catch tarpon, not sharks.
