Megalodon shark
As far as we know, the megalodon (Carcharocles megalodon) is one of the largest sharks that has existed in this world. These sharks could grow up to 18m in length and ate more than a ton of food per day. The word megalodon in Greek means `big tooth`, which fully matches these creatures, as their bite was stronger than that of a tyrannosaurus. Megalodons lived from 25 to 100 million years ago, although these sharks can still be seen in various films.

Goblin shark
The goblin shark is a rare shark species. This shark has an unusually large snout.

Cookiecutter shark
The cookiecutter shark (Isistius brasiliensis) reaches only 50cm in length, but they can bite whales, submarines, and humans. They have a small patch on their body that makes others think in the dark that they are a small fish, rather than what they really are.

Frilled shark
The frilled shark (Chlamydoselachus anguineus) is very similar to a sea snake. In fact, these sharks are not that large, their length is usually 1.5 m. Frilled sharks are very flexible and can move in ways not typical for sharks. When it opens its mouth, it looks quite scary. This shark is rarely encountered by humans because it lives in the ocean depths.

Thresher shark
The thresher shark (Alopiidae) differs from others with its large tail, which makes up half of the shark`s size. Thresher sharks feed on small fish and sometimes use their tail to herd fish into narrow places to make them easier to eat. They can also kill fish with a tail strike. They are 3-4.5 m long, but can grow up to 6m.

Megamouth shark
The megamouth shark (Megachasma pelagios) was first noticed in 1976. It acts as a filter with very small teeth, but it swims with very wide-open gills to catch jellyfish and plankton. The megamouth shark is a rare animal and encountering it is very rare. There are only 41 cases where such sharks have been seen, including a recent case where fishermen from the Philippines caught and ate a megamouth shark.

Hammerhead shark
There are about 8-9 different types of hammerhead sharks (Sphyrna), named so because of their unusual shape. Scientists believe that the distance between the eyes gives these sharks the ability to see in 360 degrees. They can easily see what is happening behind them and have perfect binocular vision. Hammerhead sharks can judge distance solely with vision. These sharks also differ from others in that they usually swim in schools and can get sunburned under sunlight.

Basking shark
The basking shark (Cetorhinus maximus) is the second largest shark in the world. It usually grows to 6-8 m in length, but some can grow up to 12 m. The width of its mouth, which it always keeps open while swimming, can be up to 1m. The open mouth allows this shark to filter plankton, crustaceans, and small fish that end up in its throat depending on how it swims.
