6 Shark Species That Will Kill You


Here the most dangerous shark species. These deadly sharks are responsible for more attacks on humans than any other underwater creature known to man.

6: Hammerheads

Although they can range in size, the great hammerhead shark is able reach a whopping 20 feet long, weighing up to 1,300 pounds & armed with razor sharp teeth. The shark’s name comes from the hammer-like structure on its head. Not only is this unusual piece of anatomy a sensory scanner, but it allows the shark to have better all-around vision. The head becomes a useful tool when they need to hunt as well. Hammerhead sharks can be found near the islands of Hawaii, in Colombia, & Costa Rica. The upper sides of the hammerheads are usually grayish-brown or olive-green, while their bellies are white. The shark’s eyes are specifically located on each end of the hammer to help the shark scan more area quicker than other predators & maximizing the fish’s ability to find its prey. Hammerheads prefer hunting alone & usually eat stingrays as their preferred meal, which they attack by using their wide head to pin them down against the seafloor. Their mouths are found on underside of their heads, with their serrated teeth looking similar to that of the edge of a saw blade. A female hammerhead can give birth to anywhere from six to 50 pups at one time. The heads of their newborns are more round than that of their parent’s. Additionally, there have been a recorded 34 human attacks in total by hammerheads over the years.

5: The Shortfin Mako

The shortfin mako shark is a member of the mackerel shark family tree, which includes the prehistoric megalodon & the great white shark. Its name is derived from the fact that it has shorter pectoral fins than its long-finned relative. They easily blend in with the ocean when cruising as their body color is blue at the top & fades to white under the belly, giving them an extremely useful camouflage for their surroundings. A full-grown shortfin mako can reach between 10 – 15 feet long & weighs close to a ton. This shark is known to reside throughout deep, tropical waters worldwide with reports of them residing off the coast of Cuba, the Indian Ocean, & the Pacific & Atlantic Oceans. In fact, because it’s not a picky eater (with a diet consisting mainly of tuna, swordfish, & herring), it’s actually capable of living in both warm & cold waters. The shortfin mako is also well-known for its speed, reaching up to 46 miles per hour & capable of making incredible leaps out of water. There have been several occasions in which this shark leaped out & landed on a boat, injuring the boat’s passengers. Although they may be small in comparison to their other family members, they have been known for their vicious attacks. There have been several human attacks throughout history that have resulted in death due to the shortfin mako shark species.

4: Blacktip Sharks

Weighing between 40 to 220 pounds, blacktip sharks are a fairly smaller shark reaching no longer than 5 feet in length on average. It gets its name from the black tips & fringes located on its fins & tail. Swimming in tropical or subtropical shallow waters of only 10 feet deep, they can soar out of water as well while pursuing schools of fish in a feeding strategy designed to stray fish in order to focus on a specific target. Additional creatures they include in their diet are stingrays, squids, & some crustaceans. It’s confirmed by DNA evidence that a female blacktip is able to impregnate herself from fertilizing her own egg without the help of a male. This rare process is known as parthenogenesis & scientists are still unsure how it works to this day. Blacktip sharks are generally not human hunters. But in the state of Florida, they’ve been responsible for 16% of all deadly shark attacks. Its wound is not as horrific as other, larger species of shark counterparts; thus, they are easier to treat. Other places they’ve been known to attack are the waters off South Africa, the Caribbean, the Gulf Coast, & the Atlantic Coast of the United States.

3: Great White Sharks

The great white shark is one of the planet’s most dangerous shark species, accounting for between half to a third of all annual reported shark attacks worldwide. As one of the largest & easily the most aggressive predatory fish, they can weigh up to two to three tons; in some instances, four to five tons. Their length reaches anywhere from 15 feet to 22 feet long. Great whites are camouflaged in the ocean by both their dorsal & ventral sides, making it easier for them to hunt prey on the surface while surging from below. Additionally, they can swim up to 35 miles per hour; which is significantly faster than the fastest human being in the world is capable of running. Their mouths are filled with rows of triangular, arrowhead-shaped teeth along either side of its jaw that are three inches long & look similar to a serrated knife. These teeth are meant for carving & devouring big chunks of the prey at any given time. Furthermore, when a tooth breaks, another one from the row behind it will replace it. Unlike the other shark species on this list that feed primarily on fish, great white sharks are oftentimes found near seal colonies as they love hunting these types of animals. They’re a versatile shark species; capable of residing in a range of water temperatures from 50 to 75° Fahrenheit in both shallow coastal waters as well as the deep sea. Thus, they’re adaptability & prevalence throughout many bodies of water throughout the world has led to over 270 documented human attacks whose fatality numbers are well in the double digits.

2: Bull Sharks

Bull sharks go by many names (such as river shark, Ganges shark, or Swan River whaler), which is one of the reasons why its fierce reputation is not as familiar as that of the great white shark. Bull sharks have a unique kidney that allows them to live in both salt- & freshwater. Reaching 11 feet long & weighing up to 700 pounds, they’re armed with serrated arrowhead-shaped teeth that give them the same biting capacity as that of the great white shark & tiger shark. It gets its name from its flat snout & stocky build. The bull shark is a highly territorial species. They’ll defend their territory by attacking any dweller that happens to venture into its vicinity, including humans. As a social species, they’ll also hunt in groups. These ruthless eaters like to implement what’s known as the “bump-and-bite” technique in which they initially bump their prey to find out exactly what it is before using their powerful jaws to bite into it. The bump is actually meant to make up for the shark’s poor vision; being nearly blind. Due to their freshwater-adaptive trait, humans are far more likely to encounter a bull shark than any other shark species due to the fact that they can travel thousands of miles up rivers & into lakes, all of which are places humans would never expect to find them. Of the 104 recorded bull shark attacks in the world, about one third of them have been fatal.

1: Tiger Sharks

Tiger sharks get their name from both their aggressive nature & the stripes running down the sides of their bodies. They’re independent, individual hunters & thus will not bother socially interacting with other sharks; even their own species. Their nickname is “the garbage can of the sea” as they will eat anything they come across in the vast ocean. In fact, marine biologists have dissected a tiger shark’s stomach before & found clothes, pigs, horse heads, bottles, & even tires. But their main diet consists of seals, fish, birds, dolphins, & turtles. Being the fourth biggest of all shark species, tiger sharks can grow to well over 16 feet long & weighing over a ton with skin eight times thicker than cowhide. But they are the fiercest of all the shark species due to their wide mouth that proportionately gives them longer serrated teeth. They’re found all over the world throughout the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, & the Mediterranean & Adriatic seas. This shark is responsible for the majority of human attacks in both Australia & Hawaii, making it the most dangerous shark in these tropical areas. Additionally, tiger sharks have an infamous reputation as man-eaters. Since they rarely miss their target, they have among the highest fatality rates per attack.
