ATLANTA, Mrs. – Let's be honest: Sharks seem to be the closest ones you can get in real marvels.
Perhaps they are not entirely in line with the legend of "Jaws", but with the big whites grows up to 20 feet long and most species are broken with several types of teeth, they are quite intense.
But the stories of their terror were very exaggerated.
Sharks, though incredible predators, do not pose much danger to humans. In fact, people are more likely to kill sharks than the other way round. According to one study, people are responsible for the death of approximately 100 million sharks a year.
For a day of awareness about the sharks, take a look at some of the surprising facts of sharks.
They fight more and more about global warming than your metal straws
Sharks are doing more work than they have most awakened among us. At the top of the marine food chain, they are biologically charged with the control of the population of the prey.
For example, they are fed with animals, such as sea turtles, enjoying large quantities of seaweed. Sea grass stores large amounts of carbon from the atmosphere. However, when the turtle population is expanded with an unsustainable level, this essential carbon storage is compromised. Sharks, natural predators with sea turtles are the only ones who can keep it. But it's hard work when people kill sharks in astronomical numbers.
They survived the dinosaurs
Sharks did not live only after a period of dinosaurs, but they were created in time before these giants even walked through the Earth. Shark fossils have been found for 450 million years, indicating that they were in the Silurian period, in the early part of the Palaeozoan era. It was 190 million years before the dinosaur appeared.
They would give the dentist a nightmare, but they will not be circumcised
With an average of 45 teeth and seven backup lines, the shark mouth would give everyone nightmares. Sharks in their lifetime lose up to 30,000 teeth, so the sea floor is with them.
Their teeth and jaws are a rather nasty duo, with a large white shark having a bite of nearly 17,790 newtons (about 4,000 pounds per square inch). However, these bad guys rarely find the way to human flesh. You have about 1 in 3,748,067 likelihood that you are a victim of a shark attack.
Their scales help them move faster
In fact, sharks are covered with teeth, even outside. They have "dermal toothbrushes", ergonomic scales that help them to glide over water with greater ease and speed. These scales help shift the shark around the sharks to rationalize their movement.
Fish are food, not friends, but sharks still do not eat much
"No Search" might try to tell us differently, but science says it's a lie. Sharks actually consume up to 3 kilograms of fish per day and are opportunist savings banks. They can use their hearing and hearing sensations to search for prey, as well as to use "side lines" on the body to sense vibrations in the water.
They have long gestation periods and some breeds where they were born
This is more weird than astounding, but it is new enough to be worth mentioning. According to a long-term study on lemon sharks, this species returns to the place of birth to steam.
And if you think it's a bad nine months, then a 43 year old shark survives pregnancy is the worst horror. Shark gestation periods can range from five months to several years, and some sharks can store sperm for months.
The only things that compete with their noses are their ears
Not only are sharks known for their acute scent, but their hearing is incredibly powerful. Sharks can hear a prey, up to one kilometer, even those bitty sounds, such as water disorders and muscle contraction.
Although people do not have 7 types of teeth, they are still worse
For every person killed in shark attack, people kill about 2 million sharks. In fact, the US average for annual sharks attacks is 19 years, with one death every two years. By comparison, lightning strikes killed 37 people a year.
