Worlds Most Bizarre Sharks

#9 Horn Shark
The horn shark isn’t a typical shark. Instead of swimming in pursuit of large prey, this slow-moving fish scrapes along the ocean floor in search of clams and oysters. Its teeth arent big and sharp enough to keep away enemies, so the horn shark has two spines on its back that are primed with venom and make great defensive weapons.
Shell Cracker:
The Horn Shark spend its feeding time on the seabed, grabbing crabs, sea urchins and mollusks with the rows of small, sharp teeth in the front of its jaws. It uses blunt teeth on the back of its mouth to crack open the hard shells of its prey.
Double Trouble:
This shark has two dorsal fins on its back, with a shark spine growing in the front of each one. The shark can jab enemies with these, and each is connected toa gland that squirts stinging venom in a victims wound.
Hard to Crack:
Horn sharks have some of the most unusual-looking eggs (shown left) in the wild kingdom. The eggs are green to gold in color and have a spiral ridge wrapped around them, like a screw. When the female lays an egg, she takes it in the mouth and wedges it between two rocks. She then gives it a couple of turns to fasten it in place so egg-eating predators cant pull it loose. The baby horn shark looks like a tiny adult when it hatches, and its venomous spines are already shark and ready to protect it.
Walk Like A Shark:
The horn shark is not a great swimmer, so it cant chase after agile prey in the water. When feeding, this fish is known to “crawl” along the ocean floor, using its pectoral fins like legs.
Color-Coded:
These sharks come in different colors, ranging from white to green or brown, and are marked with black spots or stripes. These colors and patterns help the horn shark stay hidden among rocks and plants as it rests during the day.

Creature Features:
Genus/Species: Heterodontus / Various
Size: Length up 6ft
Habitat:Mostly Coastal areas of the Indian Ocean and Pacific Oceans
Prey: Crabs, urchins, and small fish

Did You Know?
Horn Sharks that eat alot of purple sea urchins end up with purple stained teeth.

#8. Basking Shark
The basking shark is the second-biggest fish in the world, just behind its cousin the whale shark. Like its bigger relative- but unlike predatory shares-this creature doesn’t slash at prey with razor sharp teeth. Instead, it opens its huge mouth like a giant vacuum, sucks in vast amounts of seawater and swallows the millions of tiny organisms floating there. The basking shark can look frightening because of its size, but its harmless to anything much bigger than the average tuna fish.

Great What?
Because of their size and body shape, basking sharks look dangerous. In fact, many boaters mistake them for great white sharks. Basking sharks are bigger than great whites and will not harm people.
Built In Armor:
The basking sharks skin is made of rough, tooth-like scales called denticles. This shark cant bites enemies but can rub its body against them like sharp sandpaper to cause nasty wounds.
Open Wide:
The basking shark has tiny teeth, so it cant hunt down prey and tear them into bits. This beast does have huge jaws, though- up to 3.5 feet wide when fully open! The shark swims into ocean currents often near the surface, and opens up its wide mouth to let seawater pour in, and along with it thousands of tiny animals known as zooplankton. The water flushes out of the animals gills, but the plankton are caught in stiff, comb-like hairs called gill rakers, and from there enter the sharks belly.
Liquid Diet:
When feeding, a basking shark can filter through about 400,000 gallons of sea water an hour. On an average day, the shark strains and swallows about 500 pounds of food.
Deep Diver:
During the winter, basking sharks dive down to deep waters, where people can no longer observe them. Scientists used to think the Sharks went down there to hibernate but now they think this is where the creatures breed.

Creature Features:
Genus/Species: Cetorhinus Maximus
Size: Length up to 5 feet, weight over 13,400 lbs.
Habitat: All warm oceans and seas around the world.
Prey: Mostyl zooplankton
Lifespan: 40-50 years

Did You Know?
The basking shark got its name from its habit of swimming slowly at the ocean’s surface, as if it were basking in the sun.

#7. Hammerhead Sharks
Hammerhead sharks are not only the most unusual looking sharks in the ocean, but they are also one of the most dangerous. Their wide, flattened heads are loaded with sensors that help them detect the slightest movement or the faintest scent. This deadly predator not only tracks down fish, squid and shellfish, it also has been known to attack humans.
Water Wings:
Pectoral fins help the shark steer, but this creatures flat head acts as a kind of extra fin. By moving its head, the shark can change direction and make extra-tight turns when chasing prey.
A Shark With Radar:
The hammerhead sharks unique head helps track down prey. Electroreceptors stretch across the snout and help the shark pick up electrical impulses from prey that might be trying to hide. This form of radar combines with creatures eye and nostrils to give the Hammerhead a multiple sensing systems that has a broader range than any other r shark.
No Trespassing:
Hammerhead sharks can become very defensive if another predator is in the area. They are known to attack other sharks, and even human divers when they feel threatened.
Diner At The Reef:
Hammerheads swim through all parts of the ocean, but often feed near coral reefs, where there’s an abundance of prey. Stingrays are among their favorite foods.

Creature Features:
Genus/Species: Sphyrna/Various
Size: Lengeth up to 20 feet, weight up to 1,000 lbs
Habitat: All tropical and subtropical seas
Prey: Fish, squid, and jellyfish
Lifespan: Up to 30 years

Did You Know?
A hammerhead shark can sense an electrical signal as low as one-millionth of a volt.

#6. Big Mouth Shark
The first recorded discovery of a megamouth shark was in 1976 when a fishing boat dragged it up from the oceans depths. The shark was soon named for its most distinguishing feature- a big mouth.
Casual Diner:
Unlike hunting sharks, the megamouth doesn’t attack. Instead, it prefers to scoop up its prey by simply swimming with its huge mouth wide open, much like some whales.
Lights on:
The inside of the sharks mouth is thought to give off a faint glow. The light is used to attract curious prey. Once inside the sharks mouth, its lights out!
A Shy Shark:
The megamouth is a big, lumbering shark that stays deep in the ocean by day and feeds near the surface at night; This shark is not a great swimmer. It has the flabby body and soft rubbery fins.
Don’t Pick On Me!
Slow-moving megamouths make big, easy target for more aggressive ocean predators, such as sperm whales, whish have been seen attacking the megamouth.
Teeth Galore:
The megamouth has about 50 rows of teeth, but each tooth is small. Since the shark eats by swimming with its mouth open, it doesn’t need sharp teeth to snag a meal.

Creature Features:
Genus/Species: Mehachasma pelagios
Size: Length up to 17 ft, weight up to 2,200 lbs
Habitat: All tropical oceans and seas
Prey: Plankton, jellyfish, squit

Did You Know?
According to fossil records, megamouth sharks have been swimming the oceans for 20 million years.

#5 Whale Shark
Holding the title as the biddest fish in the world and with a name like “whale shark” this creature would seem certain to strike fear. But this gentle giant doesn’t bite and is interested in any creature bigger than a shrimp. It lumbers along with its huge mouth open and swallows tons of small seafood.
Stomach Turning:
Through a process called gastric eversion, the whale shark can turn its stomach inside out and push it partway out of its mouth. Anything the fish cant digest floats away.
Bite-Lite:
Like all sharks, this giant does have teeth, about 3,000 of them. They are only about one-eighth of an inch long and arent used for biting.
Mighty Mouth:
Rather than chomping down on prey, the whale shark swims with its huge mouth open up to 4 feet wide and swallows masses of seawater filled with plankton. Rakers in the sharks gills filter all the food through a relatively small stomach opening, and anything that isn’t swallowed passes back into the ocean through its gills.
Super Suction: When it finds an area that’s rich in plankton, the whale shark can turn its body vertical, stay stationary and suck the food-filled water into its mouth.
Cant Miss It:
The whale shark is easily recognizable by its unique markings. It has ridges along the sides of its back, and the tops of its body is covered with white and clue spots and stripes.

Creature Features:
Genus/Species: Rhincodon typus
Size: Length up to 66 ft, weight up to 37 tons
Habitat: Warm oceans ans seas
Prey: Animal plnkton and small fish
Lifespan: More than 100 years

Did You Know?
A whale sharks skin is about 4 inches thick- a humans skin is only 4 millimeters at its thickest.

#4 Angel Shark
Most sharks hunt food by chasing down prey and slicing the victims to bits. Not the angel shark. This fish’s flat body and dull brown color enable it to lurk on the ocean floor and launch a surprise attack. This creature likes to hide in the sandy seabed and spring out at an unsuspecting victim. That’s when this shark becomes the “angel of death”.
DeathTrap:
An angel sharks teeth are small, but this hunter has several rows of these shark weapons. When the shark bites down on prey, the ensuing struggle impales the victim even further.
Angel Wings:
Wide pectoral fins make up the bulk of this sharks body and help it glide gracefully near the ocean floor. These fins look like wings, which gave the angel shark its name.
Its No Angel:
The angel shark constantly hunts and goes after part in two different ways. During the night, this predator swims near the ocean floor and searches for crabs, lobsters and other small creatures with touch-sensitive barbels under its nostrils. During the day, it turns into an ambush hunter. It buries itself partially in the sand so its hidden from view. When fish or squid swims near, the angel shark bursts from its hiding spot with a boost from its tail and devours the victim.
Take a Breath:
Most sharks have to swim continuously to keep water flowing through their gills. The angel shark, however, has two openings called spiracles behind its eys that suck water in when the animal rests on the seabed.

Creature Features:
Genus/Species: Squatina/Various
Size: Length up to 6 ft; weight up to 180 lbs
Habitat: Shallow waters near the coasts of all continents except Antartica
Prey: Fish, squid, crabs, and lobsters.

Did You Know?
Angel Shark skin was once used as sandpaper, and its meat was thought to cure itching.

#3 Carpet Shark
Its best to tread lightly around carpet sharks. These rug look-alikes blend in perfectly with the sand, pebbles and plants on the ocean floor. They use their camouflage to set up an ambush for prey and strike victims with teeth as sharp as needles.
Hidden Jaws:
Carpet sharks jaws don’t look threatening from the outside but don’t be fooled. When attacking prey, these sharks can thrust their jaws outward grabbing victims with dozens of long, fang-like teeth and swallowing bodies whole.
Carpet Crawler:
These sharks have strong, wide pectoral fins. The predators use these to crawl over the seabed in search of mollusks and crustaceans, and also to prop themselves up to dangle the fleshy tassels and lure curious prey.
Shag Shark:
With brown bodies covered with light spots, carpet sharks blend in with the sand on the ocean floor. Dozens of fleshy tassels grow from the sides of its jaws and head, breaking up the sharks profile and making it even more difficult to see. These tassels look like the fringe of a carpet, which gives the shark its name. With such fancy camouflage, potential victims cant distinguish the sharks from the seabed and swim within range of this predators deadly jaws.

Creature Features:
Genus/Species: Orectolubus/Various
Size: Length up to 11.5 feet
Habitat: Tropical waters of the South Pacific, between Asia and Australia
Prey: Fish, squid, octopus, mollusks, and crustaceans.

Did You Know?
Fossilized teeth that look almost identical of the carpet shark have been dated back to almost 200 million years ago.

#2 Cookie Cutter Shark
The cookie-cutter shark could also be called the sneaky shark. This small predator feeds on other sharks and large marine creatures, even whales. The fish lures its victims near its body with trick lighting, then as they draw near, takes a quick bite out of the victim. The mark that’s left is perfectly circular- like a cookie cutter. The sharks then slip away to pull its trick again.
Suction Cup:
The cookie-cutter shark uses big “lips” to create powerful suction against the skin of big sharks and marine mammals. Once attached, the shark sinks its lower teeth into the victim and spins around like a can open to cut out a perfect circle of flesh.
Glow In The Dark Shark:
The cookie cutter shark cant swims up to its victims without fear of being eaten, so it has a clever way to lure them close to its dangerous teeth. Part of the fish’s belly lights up with a green glow. To any creature below, this blends in with the sun and moonlight that filters down from the surface-disguising most of the sharks body and making the rest of it look like small easy prey. The predators then swim up to eat it, but the cookie-cutter manoeuvres around them and latches on.
Going Down: This shark travels up and down like an elevator in the ocean. It spends its days in waters up to 11,500 feet deep then migrates up at night to about 1,000 feet.
Recycler:
The cookie cutter relies on super sharp teeth to be able to slice flesh from its victims quickly before they can strike back. It constantly re-grows teeth and swallow the old ones so it can re-use the calcium to build new ones.

Creature Features:
Genus/Species: Ididyius brasiliensis
Size: Length up to 2 ft, Weight up to 10 lbs
Habitat: Depths down to 11,500 ft, mostly in tropical waters
Prey: Flesh from large marine animals

Did You Know?
The disk of flesh that the cookie-cutter shark bites from its victims is about the size of a scoop of icecream.

#1 Golbin Shark
One of the scariest-looking sharks ever discovered haunts the dark depths of the ocean. The goblin sharks long snout and pointy teeth make it look like a true sea monster. This fish cant swims well compared with other sharks, but it has a wide variety of tools and skills that make it a giant predator.
Suck it up:
The goblin shark sets a unique trap for prey. The creature can push its jaws outward and widen its throat to create a strong sucking action.This pulls the victim into the sharks jaws so they Predator can stab it with needle-sharp teeth.
Hanging Out:
With short round fins and a skinny tail, the goblin shark is a very fast swimmer. The shark usually stays motionless, just hanging in the deep waters and waiting for prey.
Acting on Impulse:
The goblins sharks weirdest feature is its long nose. Soft and rubbery, this snout is full of pores called ampullae of Lorenzini. Most sharks have these prices, which are filled with nerves that can sense electric fields. All living creatures give off a little bit of electricity, and this shark can emit. With so many of its long snout, the goblin can tell exactly where other creatures are in the dark depths of the ocean.
Pretty In Pink:
The goblin sharks skin is very thin, so its blood vessels show partly through it. This gives the shark a pinkish color when it is alive. Most goblin sharks that have been observed by humans have been dead, and turned gray.
Third Eye:
A white spot on top of the goblin sharks head, called pineal window, gathers light and sends it to the sharks brain. The amount of light collected alerts the shark to whether it is day or night and acts as a kind of internal clock.

Creature Features:
Genus/Species: Mitsukurina Owstoni
Size: Lengthup to 12.5 feet
Habitat: Deep areas of the oceans
Prey: Fish, squid, and crustaceans

Did You Know?
A goblin shark bit into a cable on the ocean floor at a depth of 2,500 feet. Scientists believe the shark was attracted by the elctrical pulse running through the cables.
