Do Sharks Eat Dolphins & Octopus?

Sharks are often portrayed as mindless killers. In reality, they have a pretty sophisticated strategy for hunting their prey. And dolphins seem to know this. 

Many people believe that sharks eat dolphins, but this isn’t true. Dolphins are more closely related to whales than they are to sharks. It means they share a common ancestor and have many similarities in their anatomy. 

There has been a lot of misinformation on the topic that isn’t true. We’ll also be discussing the social life of dolphins and how they interact with sharks.

Interaction Between Sharks And Dolphins:

We’ll start by addressing some common misconceptions:

The first common misconception is that sharks and dolphins don’t interact with each other. It couldn’t be further from the truth. There have been many reports of such interactions in the wild. Some of these cases include swimming together.

Every creature has its way of adapting to ensure that it can obtain food. In the case of dolphins, their intelligence has evolved to allow them to hunt and learn from one another. As a result, they have been known to attack much larger prey together and occasionally succeed.

There have been many recorded instances of dolphin hunting sharks. They do this to drive sharks away from potential prey. Even bigger shark species are not safe from dolphins either. There have been numerous occasions where groups of dolphins were observed trying to hunt great white sharks too.

All these interactions between two different types of predators show that they are fully aware that each other has its limitation. It’s important to note that there is no documented case where dolphins go out of their way to kill sharks on purpose.

Unlike Sharks, Dolphins Are Cooperative:

When it comes to cooperating to hunt down large prey, it’s more of a joint effort. Dolphins are known to hunt together. And on some occasions, they have been seen attacking much larger prey. It’s likely that they do it sometimes by accident when trying to drive sharks away from potential food sources. 

If you think about it, this makes sense because the dolphins only get a portion of what would be an otherwise huge meal. And since they are so intelligent, it’s not difficult for them to realize that more food is available if they work together.

But dolphins don’t engage in this sort of thing all the time. It’s because the amount of energy expended in hunting is much higher than the energy obtained from eating prey. Dolphins also have their limitations, after all. So if they set out to hunt something that isn’t prey, they exhaust themselves. And there’s always the chance that they will be hunted down by larger creatures anytime.

But even outside these circumstances, dolphins are highly intelligent animals who have evolved over time. They know how to learn from one another and leverage it. The fact that two dolphin species often team up to coordinate their hunting efforts is indicative of how clever these creatures are.

Dolphin’s Hunting Instinct Explained:

One of the most misunderstood behaviors associated with dolphins is their hunting behavior. They are often portrayed as heroic creatures who go out of their way to free other animals from fishing nets. It isn’t true for all species of dolphins. Dolphins are apex predators. So if they try to set other animals free from traps, they run the risk of having an increased number of these creatures in their territory. 

It could then lead to more competition for food resources. If you’ve ever had the good fortune of swimming alongside dolphins, you’ll know firsthand how curious these creatures are. They often swim right up beside people to better look at them. They also sometimes approach from the rear to want a better look.

In this case, it’s not a sign of affection. There is a more practical explanation for this behavior. Dolphins have tiny hairs inside their nose that help them navigate and hunt in murky waters. So when they come up behind swimmers, all they’re doing is trying to get a closer look at us. It’s an interesting phenomenon, but it isn’t related to having any feelings towards humans. Rather it is simply showing curiosity about us as a species. It might look cute, but that’s all it is.

An Encounter Between Both:

When dolphins encounter sharks in their territory,  they often attack from the front. It is very risky because sharks have been known to bite dolphins as an immediate response. They also use their teeth and fins in this regard and will lash out with considerable force. It’s likely that they do this because getting attacked by sharks would severely weaken the dolphin’s chances of hunting for food in the future. 

It can also be very dangerous, especially when we consider how powerful a full-grown shark is. These creatures can use their bodies as battering rams and inflict serious damage. But despite this, dolphins take the risk and use their nimble bodies as weapons. It has been observed in many cases and is sometimes used to target sharks that are far too large for them to kill realistically.

It’s logical to assume that this is a safe way for dolphins to attack. We don’t know the true reason behind such attacks. Because we only observe them from afar, after all. We lack intimate knowledge about how dolphins think and operate. It might be a case of simply one individual trying to see how close they can get to a shark.

In most cases, dolphins won’t be able to kill the sharks because of the size difference between them. Sharks have been known to have enough force in their jaws that they could bite through bone. But these incidents are rare, and most dolphins will succeed only in injuring smaller sharks. Since both species live in very similar environments, it’s not surprising that we often find them competing for prey. Dolphins tend to love fish, but sharks prefer larger creatures such as seals.

As a result, there have been many documented cases where sharks actively try to attack dolphins out of sheer hunger. But it is very rare for them actually to catch their intended prey. It has led some experts to believe that sharks are using these attacks to practice their hunting skills.

But what needs to be considered here is that sharks are curious creatures as well. In some cases, they may attack out of a need to find out how tasty their prey might be. Since dolphins do resemble certain fish species, it’s certainly possible for them to make a mistake and bite one.


As dolphins approach sharks, they often create a bubble curtain to distract them. They might also slap the water as an instinctive warning sign with their fins. 

It’s hard to know for sure why dolphins attack sharks. But one thing is certain. These clever creatures are very capable fighters and will injure many of them during their lives. We can never observe this action firsthand. But we can be sure that these creatures are capable of using their bodies as weapons against some of the most fearsome predators in the deep ocean.

Dolphins Can Create An ‘Ambush’:

Great white sharks often tend to attack dolphins. Dolphins jump out of the water and land onto these creatures from above, which has been observed by several researchers. This behavior has been documented to occur mostly during mating season.

It might be a form of intimidation by dolphins because sharks are known for their aggressiveness. They could also use this tactic to scare off sharks that are approaching them too closely or even attempting to attack them. This way, they can avoid any unnecessary injury.

However, this kind of tactic is usually only used against the smaller species of sharks. Some scientists also believe that dolphins display this behavior after suffering from certain types of injuries. It leaves them unable to feed normally for unknown reasons. So they may do this out of desperation and pain.

It makes it even harder for us to understand what they are thinking or why they might behave this way. But it is important to note that dolphins have been known to save humans from sharks in the past. It tells us one thing for sure. Dolphins are quite intelligent creatures. And not only capable of planning but also understanding verbal commands and hand signals.

So if they display aggressive behavior towards something, then there must be a good reason behind it. It’s too bad that we can never truly know what’s happening inside their minds. Unfortunately, all animals tend to communicate differently with each other.

Most Sharks Are Selective Hunters:

To understand how sharks hunt and catch their prey, we need to first look at the dynamics of an ocean ecosystem. The ocean is home to many different predators that compete for food. For example, many fish species such as tuna and mackerel feed on smaller fish like sardines. 

Then there are bigger fish like swordfish that feed on those small ones. And finally, we get to the big guys: sharks and killer whales who can take down anything. Sharks have a diet mostly consisting of fish and crustaceans. Those animals provide more fat content, which is needed for energy due to their slow pace of life. However, they do not eat food every day. 

They will consume one big meal and then can go several weeks without feeding. This is why they are called ‘sleeping’ predators, as their metabolism is much lower than their size. It should be noted that sharks do not have the brains required for complex strategies. They are instinctual animals that can only think of what is necessary for their survival, nothing more.

What drives them to attack?

Many people think that sharks have an innate desire to attack humans due to their strength, but this is not true. It is true that adults do occasionally bite people on boats. They don’t go out of their way to try and hunt humans down on purpose.

The first thing you need to realize is the concept of ‘food’ in a shark’s mind compared to our own. Maybe you were stranded on an island with nothing else around except coconut trees. All you would need to do would be to climb a tree and grab one.

Do Sharks Eat Octopus?

Sharks will definitely eat octopus when they get the chance. However, it’s not typically a major part of their diet.
