Marco Margaritoff is a Staff Writer at All That Is Interesting. Orcas are apex predators and they can rival even the great white for their brutal killing efficiency. But orcas have been known to hunt other, smaller sharks in the past, and sharks’ livers are “very energy- and nutrient-rich,” according to Live Science. More recently, after orcas passed by a South African beach, five great-white carcasses washed ashore. In 2017, the bodies of five great white sharks washed up on the beaches of South Africa’s Western Cape province. According to a new study, killer whales terrify great whites because they brutally hunt and disembowel them for their livers. The good news for sharks is that they seem to be learning to adjust to the threat. In previous instances, the whales opted for the sharks’ livers. Sharks have been seen leaving areas when they know that there are killer whales nearby. Clearly, something even more formidable had been preying on them. Nature Scientific Reports/Salvador J. Jorgensen et al.The spatial and temporal overlap of great white sharks, orcas, and seals in the northeastern Pacific and at the Southeast Farallon Islands. The mutilated carcass of a great white washed ashore near Gansbaai, South Africa. We know who the culprit is. Dyer Island Conservation Trust / Marine DynamicsThe mutilated carcass of a great white washed ashore near Gansbaai, South Africa. The prehistoric killers who never stop swimming, smell blood from afar and fear no other, do indeed, have an Achilles heel: the orca whale. They then squish the yummy treat out of the shark and leave the rest of the corpse. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. In each of the documented attacks, the orcas have made extremely precise bites on the sharks. Great whites are commonly thought of as the apex predators of the ocean, but orcas terrify the species to death — and with good reason. Killer whales are believed to be responsible for slaying several huge great white sharks off the coast of South Africa and removing their livers with "surgical precision". All of their livers were missing — with nearly surgical precision, and mystifying accuracy. Certain parts of a shark, however, are appealing to killer whales. But there’s good reason for the shark’s fear, namely, that orcas have a predilection for their livers and will utterly mutilate them for those tasty organs. The elephant seal. the unprecedented murder spree these killer whales were on, tiger shark feeding frenzy that obliterated a whale. It was the work of orcas, which kill the sharks then make a wound near the calorie-dense shark liver. Primarily, they target the livers, stomachs, and testes of the sharks. Nature Scientific Reports/Salvador J. Jorgensen et al. According to the fishermen who witnessed the incident 1997, the orcas mushed the shark to death from the tail and then proceeded to eat its liver. Experts reckon the predator whales have acquired a taste for the sharks’ livers, which are rich in oil and fats, providing a valuable source of energy for the huge marine mammals. Squalene is shark liver oil and shark livers are filled with it, along with other tasty nutrients that orcas apparently love. Sometimes, these beasts wash up ashore with their bodies ravaged. They’ve proven that they can easily disarm a great white in an attack. The reason they target the liver (and they do it with surgical precision) is because it contains large amounts of a compound called squalene. In October 1997, tourists in a whale-watching boat off the Farallon Islands, near San Francisco, witnessed two killer whales attack a great white shark and consume its liver. Then, check out why you should be more afraid of a mako shark than of a Great White. It has become one of the foremost killers in the sea. The scientific community has since begun to assess this phenomenon with more serious, large-scale analyses. Interestingly, there is one sea creature that benefits from the bullish behaviour of the killer whales. However, years that included orca appearances — 2009, 2001, and 2013 — saw that number drop by 62 percent from their previous years. The great white shark’s liver holds a high concentration of squalene, a steroid- and hormone-producing compound attractive to killer whales. After learning about how orcas are eating great white sharks, read about groups of killer whales attacking Alaskan fishing boats. Once in range, great whites strike with rows of razor-sharp teeth that are continuously replaced throughout their life. A great white can close in on its prey at 35 mph in short bursts but orcas can sustain speeds of up to 30 mph with their long bodies and powerful tails. It’s possible even that great whites may have been part of the killer whale’s diet well before then. Orcas are exceptionally intelligent animals and can even coordinate hunting behavior in packs like wolves. Head to head: Orca vs Great White Shark; Why orcas are more ‘caring’ than ‘killer’ whales; And it seems that they have good reason: not only have orcas been known to prey on great whites, they seem to have a terrifying Hannibal Lecter-like penchant for eating their livers by making an incision near their pectoral fins with surgical-like precision and then sucking out the organ like … Global warming is expanding the geographical areas these sharks can live in. Sharks’ livers have very high concentrations of oil and fats. Shark carcasses, which surfaced in 2017, showed orca-size wounds where the aggressive whales had apparently removed only the sharks’ livers. That’s certainly a truth that anyone can appreciate: even monsters have their fears. Two decades later, the beached corpses of five great white sharks appeared in South Africa. The attacks of great white's is a more recent trend among killer whale pods. In 1997, an orca was seen ramming into a great white shark off the coast of San Francisco. “It’s like squeezing toothpaste,” explained Jorgensen, in reference to the cooperative bashing of sharks that the orcas engage in. The missing livers point to possible orca attacks—as we’ve reported before, shark livers are full of the nutrient squalene, which the orcas seem to be after. In the first interaction between great whites and orcas ever recorded, a pair of killer whales were interrupted by a great white while feeding on a sea lion and the orcas subsequently demolished the shark. The prehistoric killers who never stop swimming, smell blood from afar and fear no other, do indeed, have an Achilles heel: the orca whale. ... You may also like. According to a new study, killer whales terrify great whites because they brutally hunt and disembowel them for their livers. It is unclear but scientists believe the orcas prey on the great white sharks for their juicy liver. Published in the journal, Nature Scientific Reports, research indicates that great whites are so fearful of orcas, in fact, that they leave an area as soon as a killer whale arrives. Certain parts of a shark, however, are appealing to killer whales. Naturally, Jorgensen and his team expanded their preliminary study to observe this fear more closely. Meet The Ken And Barbie Killers: Paul Bernardo And Karla Homolka, Rhinos And Elephant-Like Creatures Once Roamed Texas 11 Million-Years-Ago, According To New Study, What Stephen Hawking Thinks Threatens Humankind The Most, 27 Raw Images Of When Punk Ruled New York, Join The All That's Interesting Weekly Dispatch. It’s a rational instinct to have — even for the prime marine predator, the great white shark. ... an organic chemical compound found in abundance in shark liver oil. The situation they’d encountered could very well be a localized fluke — an anomaly that doesn’t represent the relationship between sharks and orcas on a bigger scale. Researchers are observing that this instilled instinct to avoid predators creates a “landscape of fear,” which can have substantial ripple effects on the ecosystem at large. How do sharks react to Orcas? Thus, the orca was essentially able to drown the shark before feeding on it. We need to remember that Orcas are very intelligent mammal predators, so i guess they could also like it because of it’s taste. The accuracy of these puncture wounds sent scientists into a spiral. The killer whales bite a large slit in the side of the great whites after attacking as a pair and then suck out the 600lb fatty liver, spurning … The killer whales dissected this great white shark with surgical precision. Advertisement Advertise with NZME. It was, at that time, the first documented sighting of killer whales eating white sharks.. More gravely, it could be that killer whales are running out of their usual source of nutrition and are instead turning to great whites as an alternative meal. There are documented accounts of killer whales targeting sharks that date back decades. But the rising frequency of the attacks is a new development. So it’s not particularly unusual that a killer whale might eat a shark if given the chance. Killer Whales Are Hunting And Mutilating Great White Sharks For Their Testicles, Livers, And Stomachs — Here’s Why. Jorgensen and his team had already hypothesized how this happens, and how frequently, of course. This potentially makes a great white’s liver one of the best sources of quick energy in the ocean. Why? Sharks are susceptible to something called “tonic immobility.” When they are held upside down in the water, sharks become paralyzed because they require water to move across their gills while they swim in order to breathe. PixabayA pod of orcas traveling together, likely scaring off nearby sharks. Some feed exclusively on fish, while others hunt marine mammals such as … This was shocking, as the great white can detect a drop of blood in 25 gallons of water from three miles away. Dyer Island Conservation Trust / Marine DynamicsOne of the five carcasses calculatedly massacred by the orcas. Some scientists suggest that the answer could be the changes in the relative ranges of the animals. But then again, it might not be. The elephant seals. Scientists determined then that only one other predator could pose such a danger to these killing machines, indeed the evidence was in their name: the killer whale. It’s “apparently” for now, since no one has actually seen the orcas extracting the shark livers. The bodies ranged in size from nine feet to 16 feet, but each had large sets of puncture marks near the pectoral fins. The great white, like the other sharks that washed up, had its liver removed with "almost surgical precision", according to South Africa's Sunday Times. In each of the documented attacks, the orcas have made extremely precise bites on the sharks. They will also target the heart, as well. In 2009, Jorgensen’s team radio-tagged 17 sharks around Southeast Farallon Island. The Greater Farallones National Marine Sanctuary — a refuge for marine and wildlife off the California coast — provided the perfect site to observe the predators and their behavior. “It turns out these risk effects are very strong even for large predators like white sharks — strong enough to redirect their hunting activity to less preferred but safer areas.”. A pod of orcas traveling together, likely scaring off nearby sharks. The spatial and temporal overlap of great white sharks, orcas, and seals in the northeastern Pacific and at the Southeast Farallon Islands. This time around, they ate the stomach and testicles, too. Startled whale-watching tourists watched a pair of orcas kill a great white before consuming its liver. “We don’t typically think about how fear and risk aversion might play a role in shaping where large predators hunt and how that influences ocean ecosystems,” said Jorgensen.

So sharks and killer whales may simply be sharing the water in close proximity more often. Primarily, they target the livers, stomachs, and testes of the sharks. The murderer of these sharks knew exactly where to bite to get what they wanted: each of the sharks was missing their liver.
