Research have shown that shark population has been declined by 70% since 1970s. Sharks are the keystone species of the ocean that creates balance in the ecosystem. Without them, the entire ocean organisms will be wiped out. Sadly, we as humans have been killing them off for years, and have put false images of them as the "devil" of the ocean. This is a comic that can hopefully give you slight better understandings of shark. *disclaimer: please don't actually approach sharks in wild!
