On land, we can jump, duck, and cartwheel, but, for the most part, we live in two dimensions. Underwater, it’s a different story. Organisms float up, hover, and sink to the sea floor. This is called 'buoyancy,’ which is an important part of aquatic life. A positively buoyant animal will float, while one that is negatively buoyant will sink. When we see a fish swimming midwater or a jelly drifting in the current, they have achieved a neutral buoyancy.
