What Eats Sharks?

Sharks are apex predators in the ocean, known for their sharp teeth and powerful jaws. However, even these fierce creatures have predators of their own.

Many species of sharks fall prey to other sharks, as well as larger marine animals such as killer whales and crocodiles.

In addition to these natural predators, humans have also been known to hunt sharks for their meat, fins, and other body parts.

Natural Predators of Sharks

Sharks are top predators in the ocean, but they are not invincible. There are several natural predators of sharks that can prey on them.

In this section, we will discuss the different types of predators that feed on sharks.

Marine Mammals

Marine mammals such as killer whales, orcas, and dolphins are known to prey on sharks. Killer whales, also known as orcas, are apex predators that feed on a variety of marine animals, including sharks.

They have been observed attacking and killing great white sharks, which are known to be one of the most powerful predators in the ocean.

Dolphins are also known to attack and kill sharks, especially when they are protecting their young.

Sea lions are another type of marine mammal that can prey on sharks. They are known to attack and kill smaller sharks, such as leopard sharks and horn sharks. Sea lions have sharp teeth and powerful jaws that can crush the bones of their prey.


There are several types of fish that can prey on sharks. Tuna, mackerel, and anchovies are known to feed on small sharks and shark eggs.

These fish are fast swimmers and can easily catch their prey.

Rays are another type of fish that can prey on sharks. Some species of rays, such as the eagle ray and the manta ray, have large, powerful jaws that they use to crush the shells of crabs and lobsters.

They can also use these jaws to attack and kill small sharks.

Other Sharks

Believe it or not, sharks are also known to prey on each other. Larger sharks, such as great whites and tiger sharks, are known to attack and kill smaller sharks.

In fact, cannibalism is not uncommon among sharks.

Sharks also have a unique feeding strategy called “intra-guild predation,” where they feed on other sharks that occupy a similar ecological niche.

For example, the blacktip shark feeds on other small sharks, such as the sharpnose shark and the bonnethead shark.

Humans as Predators

Humans are one of the top predators of sharks. They hunt sharks for their meat, skin, teeth, and fins.

Shark meat is consumed in some countries, while shark skin is used to make leather products, and shark teeth are sold as souvenirs.

However, the most significant threat to sharks is the demand for shark fin soup, a delicacy in some cultures.

Shark Fishing

Shark fishing is a widespread practice, and it is estimated that up to 100 million sharks are killed by humans every year. Sharks are caught using various methods, including longline fishing, gillnetting, and trawling.

Longline fishing involves using a long line with baited hooks to catch sharks, while gillnetting uses a net that traps sharks by their gills. Trawling involves dragging a net along the ocean floor to catch sharks.

Shark fishing is a highly profitable industry, and many species of sharks are overfished.

Some species, such as the great white shark and the hammerhead shark, are also threatened by sport fishing, where they are caught for recreational purposes.

Shark Fin Soup

Shark fin soup is a traditional dish in Chinese cuisine, and it is considered a symbol of wealth and status.

The soup is made by boiling shark fins, which are then served in a broth. The demand for shark fins has led to the practice of shark finning, where sharks are caught, their fins are cut off, and the rest of the body is discarded back into the ocean.

Shark finning is a cruel and wasteful practice, and it has led to a significant decline in shark populations.

Many countries have banned shark finning, and some airlines have stopped transporting shark fins. However, the demand for shark fin soup remains high, and it is still served in some restaurants.

What predators are known to kill sharks?

Sharks are apex predators and usually do not have any natural predators. However, there are a few exceptions. Some of the known predators of sharks include killer whales, crocodiles, and larger sharks.

What is the most common predator of sharks?

The most common predator of sharks is other sharks. In fact, cannibalism is not uncommon among certain shark species, such as the sand tiger shark.

Do dolphins or orcas eat sharks?

Yes, both dolphins and orcas are known to eat sharks. Orcas, in particular, are apex predators and have been observed preying on great white sharks.

Do humans consume sharks?

Yes, humans consume sharks, particularly their fins, which are considered a delicacy in some cultures. This has led to overfishing and endangerment of several shark species.

What animals are known to prey on tiger sharks?

Tiger sharks are apex predators and do not have many natural enemies. However, larger sharks and killer whales have been known to prey on tiger sharks.

What are some natural enemies of sharks?

Apart from larger sharks and killer whales, there are not many natural enemies of sharks. However, sharks may fall prey to diseases, parasites, and other environmental factors that can weaken or kill them.
