Where is a open ocean?

The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed. It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths.

What happens in the open ocean?

Many open ocean organisms live out their existence without ever coming into contact with the shore, the seafloor, or the water's surface. They spend their entire lives surrounded by water on all sides and do not know that anything else even exists. In the case of the deep open ocean, organisms never even see sunlight.

Is the open ocean full of life?

The open ocean is home to a huge array of organisms, from microscopic plankton to the largest animal to have ever lived, the blue whale, and every size, shape and spectacular creature in-between. However, life is not evenly distributed throughout the open oceans and much of it is referred to as a biological desert.

Do fish live in open ocean?
