The oceans life contains 99 percent of the living space on the planet. The life in ocean is classified into three types.
The first type is plankton. Plankton Creatures drift, rely and float to move from one area to other and they are either microscopic or zooplankton.
The Nekton is the second type animal that can able to swim without help of tides. It has streamlined bodies to help them swim more efficiently and it can able to swim vast distances very speedy. The blue whale, Balaenoptera muscular, is the largest known animal ever to have lived on sea or land. Life begins in the seas 3.1 billion to 3.4 billion years ago. Land dweller appear 400 million years ago a relatively recent point in the geologic time line.
The architecture and chemistry of coral are very close to human being bone, coral has used to replace bone grafts in serving human bones to heal rapidly and cleanly. Alginates, derivative from the cell walls of brown algae used in beer, adhesives, boiler compounds, ceramics, explosives, paper and toys.
Benthos is the third type of organisms that live on, in, or near the seabed, also known as the benthic zone. They live in or near marine sedimentary environments and the main food; sources for benthos are plankton and organic runoff from land.
