Ah, the ocean. Everyone loves to visit you and then tries not to think about what is in the water that they are swimming in (you do realize that the ocean is EVERY sea creature's toliet, right?). And yet, while everyone loves the ocean, we have explored very little of the ocean. In this unit we discuss what we do know about the ocean. We talk about its zones, the floor features and some of the creatures that live inside it.
