To ensure survival. Without adaptations, they would die to changing environments and prey. As with many animals in the sea, they are extremely sensitive when environments change too much. For example, with overfishing certain areas, sharks have the choice to starve to death or adapt. Sometimes, this forces sharks to search for food in new places and become more desperate. This can lead to higher shark attacks on people, since there is nothing left in the water. It is important for us to stop over-fishing the oceans because we are inevitabley risking our own lives.
