Why is studying the deep ocean and ocean floor important?

It allows us to understand the effects of pressure and aquatic living conditions. It enables us to see how some fish can withstand pressure that is guaranteed to crush metal and kill humans but fish can live there unaffected by it. Also the techniques they use to navigate the ocean floor and find food. One last reason is to understand plants and how their photo receptors are different from the plants that are on earths surface.
