It's difficult to think of a creature that is more amazing in the natural world than the shark. Although sharks have a negative reputation, you might be surprised by these facts and start to think of them as sea monsters. Explore these fascinating shark facts to learn more about the most fearsome marine animal.
1 - Sharks don't have bones.
1 - Sharks don't have bones.
Sharks do not have bones, but they will still fossilize. As most sharks age, they deposit calcium salts in their skeletal animal tissue to strengthen it. The dried jaws of a shark seem and feel serious and solid; they are very similar to bones. These same minerals permit most shark skeletal systems to fossilize quite nicely. Because the teeth have enamel, they can be found in the fossil record as well.
2 - Sharks have a sixth sense.
With their killer sense of smell, sharks can also find prey by sound in the little electrical fields that these alternative animals generate. tiny organs referred to as the ampullae of Lorenzini. These small pores near their nostrils, around their head, and below their snout are a type of parapsychology. The pores are connected to long, jelly-filled bulbs, which are connected to nerves beneath their ability.
3 - They can find electricity.
Sharks use their ability to find electrical currents to track the tiny movements created by their prey. This is often referred to as electroreception. The sensors, called ampullae of Lorenzini, are little pores on the snout and other areas of the body.
4 - Shark skin feels like sandpaper.
Shark skin feels like sandpaper because it is made up of small, tooth-like structures known as planar scales, also known as dermal denticles. These scales point toward the tail and facilitate scaling back friction from close water once the shark swims.
5 - Hammerhead sharks even have 360-degree vision.
The strange head of a hammerhead shark requires incredible vision. A 2009 study found that the location of their eyes provided them with spectacular vision and, therefore, the ability to check 360 degrees.

6 - Each whale shark’s spot pattern is as exclusive as a fingerprint.
Whale sharks are the largest fish in the world's oceans. According to some estimates, they will grow to 12.2 meters in length and weigh up to forty tons! Basking sharks are the world's second-largest fish, reaching lengths of up to 32 feet and weighing up to 5 tons.
7 - In reality, blue sharks are blue.
The blue shark usually has snowy white underneath and a dazzling blue tint on the top of its body. The blue coloration of the mako and porbeagle sharks is also present, but it is not nearly as vivid as that of a blue shark. Usually sharks are brown, olive, or grayish in color in life.
8 - Great white sharks have only two blind spots.
If you would like to remain hidden from the good man-eater, position yourself either right within the front of its snout (really scary) or directly behind its head (ah, this is often a much better alternative).
9 - Not all sharks have the same teeth.
Mako sharks have terribly pointed teeth, whereas white sharks have triangular, saw-toothed teeth. Each leaves a distinct, distinguishing mark on their prey. A sandbar shark can have around 35,000 teeth over the course of its lifetime!
10 - Sharks have completely different eye colors.
Sharks living deep within the water tend to have white eyes to help them attract additional lightweights, whereas sharks living near the surface have darker-colored eyes to protect them from the sun.
