Sharks worldwide are in trouble! Big trouble, and they desperatley need our help. Well, not only are sharks some of the most beautiful and misunderstood creatures on the planet, but they are incredibly important to the global ecosystem. We often forget that salt water oceans make up more than 70% of the Earth! While humans are at the top of the ecosystem on land, Sharks are the kings of the Ocean. When the most important species of the majority of the worlds ecosystem is in trouble, everyone is in trouble!
More than 450 types of sharks exist in the world today and thousands of shark species have come and gone over the course of millions of years! Sharks are without a doubt one of the oldest creatures this planet has ever known. In fact, they envolved long before dinosaurs! The fossil record of cartilaginous fish goes back 450 million years to the Paleozoic era and sharks themselves began to appear about 400 million years ago, during the Devonian period, which is often called “The Age of Fishes”.
Sharks are threatened by human activities such as overfishing, exploitation for certain body parts, habitat degradation, and sometimes, outright slaughter. A major conservation challenge is that we are missing basic information. Although many species are widespread, a lack of fisheries data makes it impossible to assess the status of most species.
Sharing information about these splendid animals can only help to raise awareness of them!
