According to them, some seals were observed chasing, attacking and eating sharks that were mid-size to large.
The researchers believe that this discovery not only means that seals can also prey on their own predators, but it can also help scientists better understand the way the food web functions in the oceans.
Chris Fallows, an expert on great white sharks and their hunting habits discovered the seals that preyed on sharks.
Fallows came across a pack of fur seals attacking and killing blue sharks and then eating their internal organs.
He captured the seals’ behavior on camera in December 2012, while he was diving in the ocean 20 miles southwest from Cape Point, a peninsula near Cape Town, South Africa.
Fallows and his team were observing 10 blue sharks in their natural habitat when all of a sudden a male fur seal came out of the blue (ocean) and attacked the group of sharks.
According to Fallows, everything happened pretty fast and everyone was just staring astonished at what was happening in front of them.
The young male seal swam straight into the group of sharks and started to rip apart five of them. Some of the blue sharks measured up to 4.5 feet long, almost the same size as the seal.
Then, the seal snatched one of the sharks, tore open its abdomen and started eating the shark’s insides.
Fallows and his team were witnessing the shocking team and took photos while the seal killed and managed to devour five of the 10 blue sharks.
Usually, great white sharks prey on Cape fur seals, so it’s very uncommon for a seal to attack, kill and eat a shark. Seals usually eat small fish, crabs and squid. Although seals are known to attack baby sharks or eat dead sharks, it’s very rare for them to go after adult sharks almost as big as them.
The experts believe that seals attacking and eating sharks might mean that they are trying to lessen the competition for food in the ocean.
