Imagine not eating for a whole year or being pregnant for 2 years! Bizarre Shark Facts You’ve Never Heard Before!
9. Sea Slackers
When it comes to the title of sea slackers, the Greenland shark takes it home. It's the slowest moving fish in the world and it could rival the whale shark in terms of size. The Greenland shark can stretch out to 24 feet lengths and averages 8 to 14 feet in size. The ectothermic animal loves within frigid waters which could explain its 0.8 mph cruise. To put it into perspective, it moves at a speed that's one third less than the average human stride and even if you walked at half your normal speed you could still outpace this shark.
However, they don't slack off when it comes to food and they use their great sense of smell to track and locate sleeping seals attacking them through an ambush.
8. Sea Garbage Cans
The bottom of the sea is undoubtedly littered with thousands of years of waste, but at least the Tiger sharks are trying to minimize it. These sharks have been nicknamed the sea's 'garbage cans' because researchers have found odd objects from license plates, tires, clothes and even gasoline tanks intact within their stomachs.
7. Don't Have Bones
Many of us have believed for a long time that sharks have more bones humans. It's actually untrue and in fact, the bodies of sharks don't have bones. They do have a skeletal structure that's made up of cartilage. Given that cartilage has half the density of bones, it does help sharks swim faster. The flexibility of cartilage also accords sharks the elasticity to bend more compared to other boned fish.
6. Eats Tiny Krill
You wouldn't think that the Megamouth is your friendly shark just based on its name, but surprisingly its diet primarily comprises of krill. Its megamouth does come in handy when the shark is cruising through schools of krill and capturing several of them at a go. The shark is also still quite the mystery because the megamouth is rarely spotted and the first time it was documented was in 1976. However, scientists have caught and tagged 46 megamouth sharks since then and scientists keep studying the strange species.
5. Sense A Drop Of Blood In The Ocean
If you've watched Jaws and other shark-based movies then you must have the idea that sharks are drawn to blood. The sea mammals can actually taste blood within a two and a half mile radius. In fact, they can sense blood in the ocean water over a hundred miles range.
In fact, sharks have a very keen sense of smell and they impulsively act rather than think just based on what they smell. Two-thirds of a shark's brain is dedicated to the sense of smell.
4. Creepy Flesh Biters
When envisioning swimming with the sharks, you definitely do not want to encounter the Cookiecutter. This shark has the creepy tendency of biting off small cookie-sized chunks of flesh from other marine mammals, some of which are several sizes larger like the great white. They leave their victim with a circular wound that looks like something made by a cookie cutter, and that's how they got their name. They don't discriminate and even go after cables and other gear used by U.S. Navy marines. The Navy had to switch to using bite-proof, fiberglass coating on their equipment and vessels.
3. World's Largest Eggs
They are the largest known shark species and they also currently rank as the world's largest fish. The whale shark stretches out to 40 feet in length and that dwarfs the 6 to 8-inch long lantern shark which is the smallest shark in the world. For their sheer size, it only makes sense that the whale shark would also snag the world's largest egg title. One egg belonging to a whale shark discovered about the Gulf of Mexico measured 14 inches. The eggs hatch inside the mother and gives birth to around 300 live young.
2. No Food for weeks
Who would have thought that a massive sea creature like the great white could go for weeks without eating? The great white is known to hunt down the bigger marine mammals including dolphins, elephant seals, and even other sharks when pushed to it. Shockingly, the shark can go for 3 months without eating and there are some other sharks that can make it through a year without food! They are able to achieve the enviable feat by feeding off of the oil they've stored in their livers.
1. Called the Vampire Shark
The Goblin Shark is also sometimes called the Vampire Shark because it lives deep down in the sea to avoid light. These sharks are known to live at 890 to 4,300 ft depths where there's virtually no light. The goblin's pinkish/red color is due to its blood vessels showing through its skin. It works as a perfect camouflage in the depths of the sea where red appears black.
To top it all off, the goblin has an accordion jaw which it uses to sweep up prey along its way. It also has a snout-like nose resembling a giant blade filled with electroreceptors, and its function is to detect prey.
