The ocean is home to many different species of plankton, marine invertebrates, cephalopods, marine mammals and sea turtles. Other creatures that live in the ocean include numerous types of fish, sharks and corals.
The original four oceans are the Pacific, Atlantic, Indian and Arctic; however, the International Hydrographic Organization recognized the Southern Ocean as the fifth ocean on Earth in the spring of 2000.
There is only one ocean on the planet, but it is divided into five sections or five oceans. The five sections of the ocean are the Atlantic, Pacific, Southern, Arctic and Indian oceans.
An ocean current is "any more or less permanent or continuous, directed movement of ocean water that flows in one of the Earth's oceans," according to ScienceDaily.com. Currents are created by a variety of forces.
Although the ocean is one enormous and interconnected body of water, it is broken up into four regions. The four ocean regions are the Atlantic, Pacific, Indian and Arctic.
The Earth's five oceans are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean. These five oceans make up over 70 percent of the Earth's surface.
The Pacific Ocean is the largest ocean. The body of water encompasses roughly 59 million square miles, accounting for more than half of the Earth's water. All of the planet's six continents could easily fit into the Pacific Ocean.
