1) No, not all. Most sharks are simply too small to be a threat to humans.
Large white sharks are not very fond of people, although they sometimes mistakenly attack people, mistaking them for sea lions or seals, which are their favorite prey. In addition, they live at a depth where encounters with people are unlikely.
2) The most dangerous shark species is the Most dangerous shark in the world. Of all the predatory marine life, sharks are the most feared. Many horror films have been shot on the theme of their attacks on humans. However, scientists still cannot come to an unambiguous conclusion about which shark is considered the most dangerous. In total, science knows about 400 species of living sharks. Of these, the greatest danger to humans is represented by 2 species: the most dangerous great white shark, the Great white shark and the Tiger shark. It is impossible to answer the question which of them is the most dangerous shark in the world, because each of them is dangerous in its own way, and both types of sharks are fast.
3) The largest living shark is the whale shark, so named because it is the size and shape of a whale. They reach 12.6 meters in length and can weigh about 15 tons. Whale sharks are peaceful fish and feed exclusively on plankton and sometimes fish.
