A few years ago, the idea of an animal surviving the intense pressures of the deep sea was inconceivable. Today, it is a known fact that animals manage to survive at such depths. In fact, the deepest fish on record was found at 27,460 ft below sea level. Unfortunately, with current trends in pollution and deep sea fishing, many species may become extinct before they are even discovered! It is important to protect existing marine habitats, not only to protect a major resource of everything from food to tourism to coastal protection, but to ensure the survival of the creatures that make the world such a fascinating place.
