Killer “whales,” which are actually dolphins, are apex predators, and their diet includes fish, squid, seals, sea birds and whales larger than themselves, according to the Natural History Museum in London. They are the only known predators of great white sharks.
Indeed, orcas are the top predator in the ocean and small sharks are a target for some populations. Orcas will even attack and kill great white sharks just to eat their livers which are a high energy food source. A great white shark in the Gulf of Maine.
Their only known predators are certain populations of orcas and humans. White sharks are thought to have evolved 16 million years ago and are descendants from the megalodon shark, the largest shark to have ever existed.
Killer whales hunt great white sharks in packs. They work to flip the shark over to put them in tonic immobility, which means they cannot defend themselves. Humans are the shark's greatest threat.
Orcas, also known as killer whales, have been known to kill and eat several species of sharks. Since these whales possess a far superior bite force than a great white, as well as a deeper intelligence and greater speed, it is more than likely that an orca would defeat any great white in a one-on-one battle.
Orcas, commonly known as killer whales, are the only natural predator of white sharks.
Although the great white shark has a fearsome reputation, in a straight fight it is outclassed by the orca. Not only are orcas much bigger, they are also smarter. Great whites are now known to be warm blooded but orcas still have much higher metabolic rates because they breathe air.
A great white shark would win a fight against a saltwater crocodile. These deadly creatures are incredibly powerful, but the great white shark has an amazing advantage in the water. Not only would this animal probably notice the crocodile first, but it also has the speed to land a devastating attack.
Sharks and dolphins are two of the most formidable creatures in the ocean, but while sharks are often seen as fearsome predators, they are known to be intimidated by dolphins.
We know from other studies that the presence of orcas can drive great white sharks away pretty adroitly.
The giant sperm whale is almost comically larger than a great white shark and though a great white has razor-sharp teeth, a giant sperm whale could devour it if it wanted to.
Because of their intelligence and social nature, orca whales are unlikely to attack humans out of aggression or hostility. In fact, there have been numerous instances of orca whales coming to the aid of humans who were in danger, such as when a group of orca whales helped a diver escape from a shark attack.
Great White builds weaknesses are there average health and stealth. This means it is slightly hard to sneak on prey without getting caught, or simply they have to rely on fleeing and swimming away rather than hiding.
Overfishing. Overfishing is the biggest threat to sharks: more than 100 million shark are killed every year, with a large number of them being caught for their fins.
Orcas are the real apex predators of the ocean. Killer whales may be the only animals on our list that actually prey on great white sharks. Otherwise known as orcas, these intelligent mammals belong to the dolphin family and are probably the top predators in the entire ocean.
A shark would win in a fight against a dolphin. They are faster, larger, and more attuned to predation than others. Furthermore, their mouths are actually large enough to bite down on a dolphin and deal fatal damage.
A crocodile would win a fight against a Komodo dragon. Crocodiles are simply too large and too powerful for a Komodo dragon to fight back against. One likely outcome would be the crocodile waiting for the Komodo dragon in the water and dragging it beneath the waves to suffer a brutal death.
Great white sharks, to be exact. But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
When it comes to predator/prey relationships, the killer whale is an apex predator and isn't known to have natural predators. That is except humans, parasites, and diseases, which can significantly affect a killer whale's health.
Hour after hour of small bite after small bite, the orcas would slowly whittle megalodon down. Still, if there were a single mistake, megalodon would easily dispatch the orca in a single bite, but another would always be there to take its place.
It has traditionally been believed that sharks are repelled by the smell of a dead shark; however, modern research has had mixed results. The Pardachirus marmoratus fish (finless sole, Red Sea Moses sole) repels sharks through its secretions.
Their ability to sense these movements may lead people to believe that they can sense fear but ultimately the movements help them locate their prey while they're hunting. Sharks can sense the earth's geomagnetic field, but they can't sense fear.
It's pretty much common wisdom that the top predator in the ocean is the great white shark (that is, if there isn't a remnant population of megalodon hidden somewhere in the deep).
