Shark Cannibalism? New Video Shows One Shark Eat Another in Florida

Add another level to the fearsome ruthlessness of sharks. A large shark was captured on video eating a smaller shark on Jacksonville Beach Pier in Florida recently, proving the occasionally cannibalistic nature of the fearsome sea creature.

According to a report from News 4 Jax, it was Darrell Ruger who shot the video and posted it on Facebook Live. Other bystanders estimate that the smaller shark seemed to be about two feet long, while the predator appeared to be roughly six to seven feet long.

The smaller shark was supposedly caught on a fishing line when its bigger fellow shark pounced on him and ate him, a report from USA Today revealed.

This isn't the first time that a shark attacking its own have been spotted, or even recorded. Just last June, another Florida resident named Pete Hinck was fishing on his paddleboard with two friends on a kayak when they accidentally caught a small shark, the Daily Beast reported.

Just as they were preparing to let the creature go, a huge bull shark suddenly appeared and ripped the smaller one in two.

"I'm sitting here looking down and see a shark coming up, and next thing you know, it's just- all heck breaks loose," Hinck said in the video. "This thing comes out out of nowhere and just rips this shark in half."

While the fishermen all escaped unscathed from their shark encounter, the small shark can't say the same.

Sharks are known to feed on other sharks - it's brothers and sisters - even before birth. A report from Live Science in 2013 revealed that shark embryos are well-documented to cannibalize their littermates in the womb. One embryo, often the largest ones, eat everyone else except for one other embryo.

It's sibling rivalry to the extreme as the babies of different fathers compete to be born. It's also a way for the fathers to establish paternity and dominance.
