Inhabitants of the surface of the waters of the world ocean.

The fauna and flora of the surface waters of the world’s oceans has been fairly well studied, since the study does not provide great difficulties. Various types of cartilaginous and bony fish, protozoa, mammals, lower plants, corals, echinoderms and many other representatives live there. But the deeper you dive, the less explored the water layer will be. There were not many descents to the bottom of the oceans and into various depressions. Therefore, we can assume that space is much more studied than the bottom of the world’s oceans.
