If you have seen us before, you will know that we usually have a long body, which is rounded and tapered at both ends. This shape makes it easier for us to move, cutting through water like a plane cuts through the air and this way, we need less energy to swim.
Most sharks living at the bottom of the ocean, like the angelshark, have flat bodies that let them hide in the sand on the ocean bed. These slower swimming fish usually hide on the ocean floor and burst out of the sand to surprise their prey. A little bit scary if you ask me. Batoids, a type of shark such as the famous Manta Ray, are also flattened, with mouth and gill openings on their bottom side, near their stomach. I think they look like someone's stepped on them!
