The Seafloor
Do you ever find it hard to believe how many different kinds of aquatic life there are? We all know some types of marine life, like fish, sharks, and jellyfish. But what about all the other types of marine life that haven’t been found yet? Because of its size, variety, and depth, the ocean is still a very mysterious place.
There aren’t many exceptions to this rule, but most of the world’s oceans have never had holes made in them by people. Why is there still so much about the ocean that we don’t know? You might think that after so many years of research, we would know more about the ocean by now.
