- Sharks were on Earth before trees
- They reproduce slowly
- They have incredibly healthy teeth
- They are very good at finding food thanks to their electro-sensors
- His skin is really thick
- The whale shark is the largest of all sharks
- Thresher sharks use their tails as a weapon
- Shark attacks on humans are really rare
- Humans kill 100 million sharks every year
- The director of ‘Jaws ’ regrets the image that his film gave of white sharks
- Oceans are better because sharks live in them
Sharks were on Earth before trees
Sharks first appeared about 400 million years ago; 50 million years before the first tree did. They were here before dinosaurs (170 million years), mammals (205 million years), crocodiles (150 million years) and flowers (275 million years).
They reproduce slowly
The gestation of these animals is longer than that of humans. The eel shark, for example, takes 3 and a half years to gestate their young. For dogfish it is approximately 2 years. And many other species take 1 to 2 years to bring their babies into the world. Although the young are born more prepared to fend for themselves, this also means that the shark takes a long time to recover its population.
They have incredibly healthy teeth
For these creatures, teeth are so important to their survival that they need to have excellent teeth. They have several rows of teeth to avoid losing any of them while hunting. In addition, they are coated with natural fluoride that helps them last longer and be healthier and stronger..
They are very good at finding food thanks to their electro-receptors
This is an important sense for sharks. It is located on its nose and with it they are able to perceive the conductivity of the water; when discovering something that upsets it, they recognize where it is and can thus find its food.
His skin is really thick
Because males bite females during mating, they have developed thicker skin. In addition, it is not covered with scales but with dermal denticles. As a result, they have a smoother and more hydrodynamic skin..
The whale shark is the largest of all sharks
They are usually about 12 meters tall and this species feeds by filtration. The smallest shark lives in the Caribbean, it is called a lantern shark and when it is adult it reaches only 20 centimeters.
Thresher sharks use their tails as a weapon
This type of shark whips its prey with its long tail. From the impact they are stunned and so you can easily hunt them.
Shark attacks on humans are really rare
Of the hundreds of millions of people who swim in the oceans each year, only between 50 and 70 people are bitten. Of all the encounters, an average of 6 are fatal; nothing compared to what we do to these animals.
Humans kill 100 million sharks every year
Most are killed by fishing vessels or caught in their nets. About a quarter of all shark species are endangered. Fortunately, many countries have already passed laws that protect these animals.
The director of ‘Jaws ’ regrets the image that his film gave of white sharks
The population of white sharks has been threatened after the novel and the film that recounted the attack of a shark on the population of an island. The fishermen saw it as a great trophy, just like Moby Dick. After that, its creator became a great defender of these animals.
Oceans are better because sharks live in them
Being predators, they maintain balance and control the population of other animals. Without them, the other species would grow so large that there would be disastrous consequences for the food chain.
