Microscopic plants and animals called plankton live on the surface of. Ooze is described as the remains of that settle on the ocean floor. Separated into two new genera these organisms are a type of xenophyophores that live on the ocean floor and form elaborate shell like exoskeletons called tests from the environment around them. In total 4 4 10 20 nematodes inhabit the earth s topsoil or approximately 60 billion for each human with the highest densities observed in tundra and boreal forests.

A person who studies ocean life is called a marine biologist. In most of the world the ocean floor is very deep averaging 3 790 meters 12 430 ft in depth. Contrary to popular belief most of the sea floor known as the open ocean is not really a habitat for animals just a place they pass by on the way to somewhere else. The area along the ocean floor that consists of sand silt and dead organisms is called the benethic zone.

The ocean is also filled with lots of plants which provide food homes and protection for ocean animals. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.
