Off the coast of Australia, a fisherman grabbed a massive shark that was being eaten by another, even larger beast.

According to Sammy Hitzke of Sammy Hitzke Fishing, he and his other fisherman put the bait at a depth of roughly 1,500 feet in the hopes of catching a swordfish.

"We believed it was either an extremely huge one or foul hooked," he added, explaining that the shark they hooked originally felt like a swordfish.

Two fishermen were left speechless after pulling in a catch for over five hours only to discover a massive shark missing the majority of its body, as per Metro.

In the depths of the ocean, the half-eaten "monster of the deep" was apparently assaulted by an even larger predator.

Sammy Hitzke and his companion Shaun Whale are seen in footage straining to land the beast in Australia.

During a journey off the coast of Queensland, the two guys thought they had discovered a giant fish.

They discovered they had already been reeling in a massive shark when they eventually brought their capture near to the boat.

"We were both a little bit astonished," Hitzke said. "Neither of us had ever seen a thresher shark in person, so it was a shock to witness one, and the fact that it had been half-eaten made it much more shocking, the remains were around 100kg [220lb]," as per Newsweek.

Because Shaun isn't particularly strong, he had to raise most of the shark alone, and there was a point where he didn't believe he'd be able to get it in at all.

Several huge marine animals, including great white sharks, bull sharks, tiger sharks, and giant squid, may be found in the seas off the coast of Australia.

Tony Walker, an Australian commercial fisherman, was working in the Coral Sea off the coast of Australia in March when he picked up three enormous fish with unusual bite marks.

He believed the fish was attacked by a gigantic squid.

The giant squid has enormous suckers on their limbs that they use to draw victims to their beaks, where they cut the meat into bite-sized bits.

Walker claimed that he had always suspected the presence of huge squid in the vicinity, but that he had never seen one.

Despite being the world's largest invertebrate, experts are still baffled by the enormous squid, as per the National Geographic.

The largest of these elusive monsters ever discovered was 59 feet long and about a ton in weight.

Their inhospitable deep-sea environment, on the other hand, has made research extremely difficult, and practically all scientists know about them comes from carcasses that have washed up on beaches or been brought in by fishermen.

Scientists investigating these enigmatic critters' fortunes have just begun to flip. Researchers in Japan captured the first photographs of a living giant squid in 2004.

A live 24-foot female giant squid was caught and brought to the surface by scientists from Japan's National Science Museum in late 2006.

The biggest eyes in the animal kingdom are those of giant squid and their relative, the gigantic squid, which measures 10 inches in diameter.

These huge organs enable them to identify items in the dark where most other creatures would not be able to see them.

They have eight arms and two larger feeding tentacles, just like other squid species, to assist them to deliver food to their beak-like mouths.

Fish, shrimp, and other squid are most likely on their menu, and some speculate that they may even assault and consume tiny whales.
