Sharks are apex predators living in oceans, and they also devour a lot of food due to their large size. Daily Star reported another human-shark encounter that left two fishermen terrified. They witnessed how the massive shark emerged from the water to take a chunk of the tuna left hanging in their boat.

A Great White Shark is attracted by a lure on the 'Shark Lady Adventure Tour' on October 19, 2009 in Gansbaai, South Africa. The lure, usually a tuna head, is attached to a buoy and thrown into the water in front of the cage with the divers.

Monstrous Shark Tears Off Hanging Tuna

The shark was caught on camera circling the small boat of amateur fishermen off the coast of Mallorca in Spain in June last year. The video of the terrifying encounter with the hungry shark just recently resurfaced, which caught the attention of many people on the internet.

The two fishermen waited patiently and gently shook the fish a few times to see whether the shark would return. They were shocked when the monstrous shark suddenly appeared and dragged the 5-foot tuna hanging on their boat.

The gray shark wrangled the head of the tuna fish a few times before disappearing into the water. They added that the hungry shark dragged the fish to the back of the boat as it thrashes to get another bite. 

The fishermen were able to take a video of the incident, which was shared by a local media outlet and spread online via WhatsApp.

Meanwhile, a separate human-shark interaction also happened in Cape Cod Bay, Massachusetts. A family of five was terrified upon seeing a shark swimming along with their boat during a lobster-hunting trip.

The video was shared on the Facebook page Billingate Charters on June 14. The family could be heard screaming in the footage, "Holy smokes, that thing is huge, dude!" The shark was estimated to be about 15 feet long.

 Despite the terrifying experience, the company owner, David Stamatis, said the family was thrilled with their trip. They not only caught a bunch of fish and lobsters but also had a close encounter with a shark.

Shark's Diet: How Much Do They Eat?

Sharks have preyed on almost all animal life in oceans, from the smallest fish to enormous whales. But these apex predators also have a particular preference for their food, including certain species of fish and seals.

According to American Oceans, sharks' prey depends on their species and where they live. 

Even small sharks sometimes end up being food to bigger sharks. Some common fish species they hunt include tuna, salmon, bass, rays, and redfish. They hunt using sensory receptors called lateral lines, which are located on their sides and are almost common in all fish.

Sharks also eat seals and sea lions who spend a significant amount of time in the water, making them perfect prey for large sharks, such as great white sharks. They thrust themselves toward the surface and grab seals or sea lions with their powerful jaws.

Great white sharks can sometimes jump out of the water, reaching up to 10 feet. Seals and sea lions have high fat due to their blubber, making them extremely nutritious for a large shark.

Other marine species they eat are mollusks, like squid and octopus; crustaceans, such as crabs, lobsters, and other shellfish; dolphins and small whales; and plankton.

A shark eats depending on how big they are. In general, sharks eat between 0.5% to 3% of their total body weight each time they hunt. 

However, their stomachs are not the best at digesting their food, even if they have teeth made for tearing up food. They usually need a couple of days to fully digest their food before hunting again.
