we mentioned a lot about the great white sharks. so let’s take a look at them too. they can smell a single drop of blood floating in 10 billion drops of water they can detect movement from as far away as 820 feet and with powerful streamlined bodies and razor-sharp teeth, great white sharks are as scary as it gets. but don’t worry they generally don’t eat people and most attacks on humans aren’t fatal. anyway, nevertheless I recommend you to be sure that you’re not bleeding if you’re gonna get in the ocean. great white sharks prefer to Hunt sea lions, seals, dolphins, small toothed whales, sea turtles, sea birds and even the rotting flesh of dead animals. they can reach speeds of 43 miles 69 kilometres per hour. which allows them to surprise their prey and subdue it with a single bite. great white sharks can even leave the water completely breaching like whales. when attacking prey from underneath.
orcas will work together to catch larger prey or groups of prey such as schools of fish
. it’s difficult to imagine the voracious and predatory great white shark as prey could orcas really be overpowering them and removing their livers. in 2017 the bodies of five great white sharks washed up on the beaches of South Africa’s Western Cape Province the bodies ranged in size from nine feet to 16 feet but each had large sets of puncture marks near the pectoral fins. the murderer of these sharks knew exactly where to bite to get what they wanted. each of the Sharks was missing their liver. clearly, something even more formidable had been preying on them. 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. orcas are also apex predators and they can rival even the great white for their brutal killing efficiency orcas seemed to have developed a way to take on the great white safely. in 1997 an Orca was seen ramming into a great white shark off the coast of San Francisco the force of the blow stunned the shark and allowed the Orca to flip the great white over and hold it in that position 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 to breathe. so the Orca was essentially able to drown the shark before feeding on it. orcas are exceptionally intelligent animals and can even coordinate hunting behaviour in packs like wolves. they’ve proven that they can easily disarm a great white in an attack.
why killer whales attack sharks?
killer whales are a step above large predators. like the Orca tend to go after prey animals that have a lot of rich fat on their body. which means that most of the shark is unappealing as a meal certain parts of a shark, however, are appealing to killer whales. in each of the documented attacks, the orcas have made extremely precise bites on the sharks primarily they target the livers stomachs and testes of the Sharks and this might actually explain what’s going on. shark’s livers have very high concentrations of oil and fats. they are also very large compared to other animals. this potentially makes a great whites liver one of the best sources of quick energy in the ocean. orcas seemed to have learned this and are targeting sharks specifically for their nutrient-rich livers. there are documented accounts of killer whales targeting sharks that date back decades. it’s possible even that great whites may have been part of the killer whales diet well before then.
but the rising frequency of the attacks is a new development some scientists suggest that the answer could be the changes in the relative ranges of the animals. shark populations have been growing due to restrictions on fishing global warming is expanding the geographical areas these sharks can live in so sharks and killer whales may simply be sharing the water nearby more often. 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. the good news for sharks is that they seem to be learning to adjust to the threat. sharks have been seen leaving areas when they know that there are killer whales nearby.
Imagine being a shark flipped over by orcas and one of them says “get the liver”
