Sharks star in blockbuster movies as bloodthirsty villains, but in reality, they’re far more engaging and complex than what they’re used to in popular culture.
Based on fossilized teeth and scales, scientists believe that sharks date back more than 400 million years, long before dinosaurs. The ocean’s top predators have evolved into about 500 species of varying sizes and colors, with different diets and behaviors. In this post, we have compiled a list of the most shocking facts about Sharks.
Sharks might not be a substantial chance to us, however we’re to them. Humans are accountable for drastic declines in shark populations. Overfishing is the most important chance. A hundred million sharks are killed every year, mainly to deliver a call for a luxurious Chinese dish known as shark fin soup. Some fisheries permit the capture of entire sharks, like some other fish, whilst others have outright banned shark fishing.
Sometimes fishermen reduce the fins off stay sharks and sell off the animals, finless, lower back into the ocean, wherein they`ll drown or bleed out. This exercise is known as shark finning, and it’s performed to shop area at the boat (the fins are the maximum treasured a part of a shark) and to keep away from surpassing fishing quotas.
