When someone says the word â€śSHARKâ€ť most people think of a massive, grey, toothy, underwater animal; basically they are imagining a Great White. In fact sharks come in all shapes, sizes and even colours! Thatâ€™s why weâ€™ve made a top ten list with some of the planetâ€™s most amazing sharks, featuring everything from hammerheads to species with horns, saws and even frills.
Angel Sharks (Squatina squatina)
Location: North-eastern Atlantic
Size: up to 2.4m (3 feet 11 inches)
Status: Critically Endangered
What makes it unique? Their flat, wide bodies!
These sharks look more like a ray than a member of its own species. They have large flat bodies with big pectoral fins. This shape allows them to hide under mud or sand and wait for prey to come close. When it is the perfect time, these sharks shoot out of their hiding spot and catch their lunch.
Horn Shark (Heterodontus francisci)
Location: Along the Western Coasts of the Americas
Size: Around 1.2m
Status: Not Yet Evaluated
What makes it unique? The two large spines on their backs!
If a predator attempts to gobble up one of these sharks, it is certainly in for a surprise. As the predator bites down, the spines on the Horn sharkâ€™s back will stick into the predatorâ€™s mouth and the Horn shark can make its get away.
Great Hammerhead Shark (Sphyrna mokarran)
Location: In most of the worldâ€™s oceans
Size: up to 6.1m, making them the largest of the Hammerhead species (20 feet)
What makes it unique? Their heads!
It is easy to spot a Hammerhead because their heads are, well, shaped like a hammer. Their eyes are placed on either side of the hammer which allows them to see a much larger area than other sharks. Once theyâ€™ve spotted their prey of choice, stingrays, they use their heads to pin them down so they canâ€™t get away.
Basking Shark (Cetorhinus maximus)
Location: Arctic to temperate oceans of the world
Size: Basking Sharks are the second largest living fish in the world reaching 11m (36 feet!)
Status: Vulnerable to Endangered
What makes it unique? The way they eat!
There are three species of filter feeding sharks (Whale shark, Basking shark, and the Megamouth shark) but Basking sharks are unique among them. Where the other two suck in water and filter to collect their prey, Basking sharks leave their mouths open as they swim, filtering water passively.
Location: Indo-pacific and Atlantic oceans
Size: Can grow to 1.5m long (about 5 feet)
Status: Least concern to Near Threatened
What makes it unique? Their snouts!
Their snouts are long and lined with teeth which they use to slash their prey. About half way down their snouts are very sensitive catfish-like whiskers called barbels that Sawsharks use to find prey hiding out on the bottom of the sea floor.
Interesting fact: There is only one other fish that has long blade-like snouts: the saw fish. These two fish look very similar but you can tell the difference because sawsharks have barbels and the saw fish does not.
Common Thresher Shark (Alopias vulpinus)
Location: Temperate Oceans
Size: About 6m (about 19 feet and 8 inches)
What makes it unique? Their tails!
These sharks are big! But what makes them so big is the fact that about half of their size is made up by their tail. They use it as a whip to disorient, stun and even kill their prey!
Wobbegong or Carpet Sharks (Orectolobidae)
Location: In the Indo-Pacific Ocean
Size: 1.8-2.4m (6-8 feet)
Status: From Least Concern to Near Threatened
What makes it unique? Their appearance and the way they catch their food!
When Wobbegongs lay on the sea floor they look just like seaweed-covered rocks, which comes in handy for catching food. They lay still, waiting for some prey to swim by, then they pounce! Wobbegongs have special gills that allow them to stay still, while other sharks need to move in order to breathe.

Nurse Shark (Ginglymostoma cirratum)
Location: Tropical and Subtropical parts of Atlantic and Pacific
Size: Up to 3m (about 9 feet 10 inches)
Status: Vulnerable in Brazil, Colombia and US waters
What makes it unique? The way they eat!
Nurse sharks spend their days sleeping on the bottom of the sea but when the sun goes down, they go searching for food. Hunting at night allows them to sneak up unsuspecting sea creatures that are fast asleep. Like the Saw shark, they have barbels that they use to feel around on the sea floor to find the prefect snack. Nurse sharksâ€™ can literally suck their prey out of their hiding spots because they can hoover around the floor like a vacuum.
Goblin Shark (Mitsukurina owstoni)
Location: Parts of the Pacific, Indian and Atlantic Oceans but very rare
Size: about 3.8m (over 12 feet and 5 inches)
Status: Least Concern
What makes it unique? Their protruding jaws!
When swimming casually, these sharks look pretty much like any other shark. All that changes when they go to take a biteâ€¦ their jaw shoots out and they snap up their prey with their long sharp teeth. With their jaws fully extended, they truly look like monsters from the deep.
Frilled Shark (Chlamydoselachus anguineus)
Location: Found in most of the worldâ€™s oceans but it is very rare
Size: Up to 1.5m (4 feet 11 inches)
Status: Near Threatened
What makes it unique? Their bodies!
Frilled sharks have lizard-like features and snake-like bodies. Their gills meet on the underside of their throats so it looks like they have frills. Inside their wide mouths there are over 300 sharp three-pronged teeth. These definitely arenâ€™t sharks you would want taking a bite out of you!
