To spite the exaggerated killer, man eating image that sharks have gotten over the past few years, sharks are an extremely important part of the oceans ecosystems. Unfortunately, nearly a quarter of the various species of sharks around the world are currently over exploited; many to the point of probably extinction.
Like many different species of marine life, sharks have fallen victim to habitat loss, pollution, and decreasing food supplies as well as sports fishing where they are slaughtered by trophy hunters. This along with fear and little understanding about the true nature of sharks and their vital role in the ocean's ecosystem has lead to a disturbing drop in the number of shark species around the world.
To spite the blood thirsty hunters that people often associate with sharks, most sharks present no threat to humans and in fact there are some that are not even hunters at all. In this look at endangered sharks from around the world we will take a brief look at three such sharks which are known as filter feeders including the basking shark, the whale shark, and the megamouth shark.
Filter feeders are so named because they have rather large mouths with a jaw that allows them to use their mouth like a type of net. They take in the water around them and then filter out of it the food that they need for their survival which include plankton, krill, and algae.
