Top 10 Biggest Sharks in the World
There are about 460 known species of sharks, making them one of the most prolific of marine animals.
Some of them are quite small, no bigger than a house cat, yet some of them can grow to be very
massive. Today we will be looking at 10 of the largest sharks in the world. Make sure you stay tuned for
number one, it is the perfect example of a gentle giant.

Number 10. The Bigeye Thresher Shark
There are three known species of thresher sharks, all of them share characteristics that make them
easily identifiable; their long whip-like tails. This long curving, upper tail lobe is nearly as long as the
entire fish’s body. The bigeye thresher shark, however, has something that sets it apart from the other
two; its big bulging eyes that allow it to see better in the pitch dark depths where it hunts.
Male Bigeye Thresher sharks mature at about 3 meters while females mature at 3.5 meters, big enough
to take the tenth spot on this list. These sharks are pretty much widespread and inhabit tropical as well
as temperate waters including the Atlantic Ocean and Mediterranean Sea. They can also travel huge
distances, with one tagged individual travelling 2,767km between New York and the Gulf of Mexico.
They can be found close to the shore, where it never shies away from humans, as well as in the open
seas.
Their prey typically consists of small predatory fish, and squid.

Number 9. The Bluntnose Sixgill Shark
The Bluntnose Sixgill Sharks are primitive sharks belonging to the Hexanchidae family, otherwise known
as Cow Sharks. These deep-water predators are distinguished by the following features: they have six
pairs of long gill slits on each side of their broad head, comb-like, yellow lower teeth, and a long tail.
Their average length is roughly 4.8 m, a fact that landed them the ninth spot on this list, although some
reported sightings suggest that individuals can grow longer.
The sixgill shark is a slow but strong swimmer. Although it is a fierce hunter, it still has to stay aware of
its own predators. Potential threats include the Stellar’s sea lion, the killer whale, and the great white
shark.
The Sixgill is one of the widest ranging sharks, inhabiting continental as well as island shelves of the
world’s temperate and tropical seas. This makes it one of the highly migratory marine species. It prefers
deep sea habitats, below 90 meters. Adults exhibit a daily vertical migration cycle, which means they
stay in deeper waters during the day, and swim up to shallower waters at night.
Males reach maturity at 14 years while female reach sexual maturity at 18 years, and they are believed
to live up to 80 years in the wild.

Number 8. The Common Thresher Shark

Also known as Fox Shark, the Common Thresher Shark obtains its name from its characteristically large
caudal fin, which in most cases can be as long as the fish itself. The Common Thresher Shark is the
largest of its kind and can grow up to 6.1 meters and weigh up to 500 kilograms. They eat pelagic
schooling fish such as sardines, mackerel or juvenile tuna.
Like many shark species, they are ovoviviparous which means that fertilization of the eggs and
embryonic development occur internally, resulting in small litters of two to four large, well-developed
offspring, up to 150 centimeters at birth. When the young fish exhaust their yolk-sacs while they are still
inside the mother, they begin feeding on the mother’s unfertilized eggs; this is known as oophagy.
Threshers Sharks commonly inhabit the Indian and Pacific Oceans. They reach maturity between 9 and
14 years old and can live for up 22 years in the wild. Thresher Sharks are largely solitary and only get
into groups when mating or hunting. They mostly hunt schools of fish in open waters and prefer
Mackerels, Tuna and seabirds.

Number 7. The Great Hammerhead Shark
Possibly one of the most known sharks around, the Great hammerhead sharks obtains its name from the
flat, T-shaped snout that makes it stand out. Its eyes are wide-set to enhance its visual range. In
addition, its head is covered by tiny organs called ampullae of lorenzini which they use to detect the
vibrations made by their prey in the water.
The great hammerhead shark can grow up to 5.5 meters long and weigh 450 kilograms. Its coloration
can range from grey-brown to green on the dorsal fins, and cream-white on its ventral sides.
Their teeth, which are jagged and triangular, are the perfect tools for devouring their chosen prey which
includes crabs, squids, other sharks, herrings, sardines, jacks, guitar fish, sting rays and eagle rays. They
hunt twice a day, once at dawn and one more time at dusk.
