How Sharks Work

Every summer, millions of overworked servants from around the world are absent from work, clean up their cars and spend a comfortable and relaxing family holiday at the beach. Small toe saltwater, a small amount of sun and sand is a healthy relief for overwork and overworking. When the children make a castle of sand, throw a Frisbee and swim in the sea, their parents will come back. A person is walking around the beach looking for love. Children gathering at university is the same as in 1999. It was full of sunshine and fun all before shouting the whistle by a watchman and beach comaer wanting to hear it - sharks!

If you see the news, you may think that the possibility of being attacked by a shark is very high. The truth is that noninvasive shark attacks are very rare - they are just attractive headlines. You may die with bees, bees, or snakes instead of sharks. The probability of thunderstorm of your death is 30 times that of shark attack [Source: International Shark Attack Archive]. However, since movie makers Stephen Spielberg brought the movie "White shark" to the big screen in 1975, vacationers who love the beach may avoid shark attack behind their heads.

There is no doubt that a shark is one of the most terrible creatures on the planet. However, they are also one of the most complex and long lasting. The oldest shark fossil dates back more than 300 million years ago before the dinosaur age. Several existing shark species like Horn Coral have maintained basic physical characteristics over 150 million years. Scientists believe that this amazing longevity is due to the excellent physiological development of sharks. Sharks have some special features that make them very effective, whether they are hunters or survivors

Sharks are an important part of the marine ecosystem, and unfortunately overfishing puts many shark species in danger of extinction. The International Conservation Union for Nature Conservation (IUCN) lists three shark species with vulnerable thighs worldwide. Mako sharks move from a place close to the threat to a fragile place, and fan-shaped hammers are almost in danger of extinction. If fishing methods are not subject to more stringent regulations, these are just a few of the nasty species.

The view of sharks as dangerous animals is prevalent by isolated deprecation attacks such as the shark attack on the Jersey Coast in 1916 and popular fictitious works on shark attacks such as the white sharks movie series. Peter Benchley, the author of the white shark, and Steven Spielberg, director of Jaws, later tried to break up the image of the shark into a monster that eat away. Until recently, only a small number of benthic sharks such as horn sharks, sturge sharks, and shark sharks survived for more than a year under a tank condition. This makes people believe that sharks are difficult to capture and difficult to capture and transport. More knowledge has allowed more species (including large marine sharks) to live with longer captive bodies and safer transport technologies, enabling long distance transport. For a long time [when?

The average life expectancy of sharks is 20 to 30 years. Certain sharks can take up to 18 years to fully mature. Adult sharks are different in size and weight because there are more than 250 types of sharks. The largest shark species, whale sharks can be up to 40 feet long, but the smallest sharks, short sharks are only 10 inches long

Most sharks are predators. Many shark species will become active after hunting at dusk or at night. Most sharks eat other fish. Large sharks such as white sharks (Carcharodon carcharias) and shark sharks (Galeocerdo cuvier) prey large marine mammals such as seals, sea lions, dolphins, large fish, turtles and even seabirds. Carcharias), Tiger shark (Galeocerdo cuvier), and bull shark (Carcharhinus leucas). 8 DoEE understand that shark species known to be harmful to humans do not use humans as prey It is thought that the shark is confused with usual prey.
