Hammerhead sharks can be found in tropical waters worldwide. They are most commonly found in schools around the Islands of Darwin and Wold in the Galapagos.
But they can also be found off the coast of Florida, Australia, and many other places in which many people reside.
For this reason, there are many people who are looking to learn more about hammerheads, and specifically are hammerhead sharks aggressive?
In short, hammerheads are not aggressive toward humans, but they are very defensive and will defend themselves if provoked.
Let’s take a closer look…
Are Hammerhead Sharks Truly Aggressive?
The Great Hammerhead usually feeds on prey on the seafloor, such as Stingrays, Octopuses, and sometimes other Sharks.
In the wild, hammerheads are aggressive hunters. The ocean is a dangerous place, even for sharks, so they need to be fierce and aggressive in order to survive.
After all, hammerheads are carnivores, which means they need to hunt and kill other animals in order to eat.
The hammerhead shark’s distinctive head is designed for agility and panoramic vision, which makes the hammerhead an exceptional hunter in the wild.
Hammerheads will aggressively hunt their prey by scanning the seafloor for any signs of life.
Although Stingrays and Octopuses are excellent at hiding, they cannot hide from the excellent hunting sensors of the hammerhead shark.
The shark uses all of its powerful senses to detect prey, and once it finds what it is looking it will strike by using its hammer-shaped head to pin its target to the seafloor.
Once the prey is pinned, it will take a good bite and tear its prey to shreds before finishing its well-deserved meal.
Are Hammerhead Sharks Aggressive Towards Humans?
Hammerhead sharks rarely ever attack humans. Much like other sharks, they are intelligent enough to know that we are not on their menu.
They are typically considered harmless to humans. That said, their huge size and defensiveness can make them dangerous and not a shark to be messed with.
The average size of a hammerhead shark is 13.1 feet (4m) and has a weight of 500 pounds (230kg).
They can be very intimidating sharks, with the largest ever recorded being 20 feet (6.1m) and weighing 991 pounds (450kg).
Thankfully, we humans really aren’t an impressive-looking dish for sharks, full of bones with little flesh and a lot of kicking and screaming to go with it.
Why would hammerhead sharks want to attack us when they can easily take out prey that has a lot more to offer for them?
Hammerhead sharks have never killed anyone. In fact, there have only been 16 unprovoked attacks on humans around the world, non of which proved fatal.
That said, there is no question that if a hammerhead wanted to kill a human, it certainly could. They are wild animals after all, and should be treated with the utmost respect.
Despite their large size, a hammerhead would much more likely bolt into the depths than attack a human, which is why they almost never attack people.
Only three of the nine hammerhead species (Great, Scalloped, and Smooth) have ever attacked a human, the vast majority of the time these sharks are safe for humans.
Can Hammerhead Sharks Be Friendly?
Hammerheads are known to be shy sharks, and they are not particularly friendly towards humans.
They are inquisitive by nature, and will sometimes swim close by, but oftentimes will flee once they see humans around.
These sharks are not aggressive towards humans, and often totally ignore divers when in the wild, but that doesn’t mean they are friendly.
You should never approach a hammerhead if you do encounter one in the wild, if the shark is friendly and inquisitive it will come to you.
Is It Safe To Dive With Hammerheads?
Hammerhead sharks are easily spooked, and they will often swim away to avoid divers or fishermen.
However, hammerheads sometimes swim in large schools, and when in the comfort of a school they are more inquisitive and will swim right up to divers to check them out.
When with a school of hammerheads, they typically ignore humans and are very unlikely to take a bite, which makes them safe to dive with for the most part.
As always, they are wild animals and extreme caution should be taken when around hammerheads in the wild.
They are large, powerful, and defensive animals that if threatened may strike.
They have large teeth that could easily do a lot of damage to a human, so you should always make sure you’re with a professional and be incredibly careful.
What Makes Hammerhead Sharks Aggressive?
It’s incredibly rare for hammerheads to be aggressive toward humans, and they typically will only do so if they feel threatened or in danger.
Hammerheads may also show aggression if they are in the presence of food and they feel they need to compete.
These are generally a safe species of shark for human divers and are not nearly as aggressive as some other sharks such as Bull or Great Whites.
Hammerheads, like most sharks, can sometimes show aggression when they are confused or curious. If they see something splashing in the water, they may swim up to it to investigate.
Final Thoughts
So, are hammerhead sharks aggressive? No, not really.
They are timid, shy sharks that are unlikely to ever bite a human, but much like all wild animals will do so if they feel they need to protect themselves.
They are much less aggressive than the likes of Bull Sharks, Great Whites, and Mako Sharks. In fact, they are probably one of the least aggressive species of shark.
That being said, this doesn’t make them any less dangerous when in the wild. Sharks can sometimes be unpredictable so it’s wise to always be incredibly careful when around hammerheads.
They are large, powerful sharks that could easily cause injury to humans if they want to.
Hopefully, this post has been helpful and you’ve learned a thing or two about the hammerhead sharks’ aggression.
