OCEAN LIFEThe oceans contain 99 percent of the living space on the planet.The blue whale, Balaenoptera musculus, is the largest known animal ever to have lived on sea or land. Individuals can reach more than 110 feet and weigh nearly 200 tons_more than the weight of 50 adult elephants. The blue whale's blood vessels are so broad that a full-grown trout could swim through them, and the vessels serve a heart the size of a small car.Hydrothermal vents, fractures in the sea floor that spew sulphur compounds, support the only complex ecosystem known to run on chemicals, rather than energy from the sun. Gigantic tubeworms and mussels thrive in densities of up to 65 pounds per square foot around vents.The oarfish, Regalecus glesne, is the longest bony fish in the world. With its snakelike body_sporting a magnificent red fin along its 50-foot length_horselike face and blue gills, it accounts for many sea-serpent sightings.Green turtles can migrate more than 1,400 miles to lay their eggs.A group of herring is called a seige. A group of jelly fish is called a smack.

Facts about the World Oceans There are 328,000,000 cubic miles of seawater on earth, covering approximately 71 percent of earth's surface.By volume, the ocean makes up 99 percent of the planet's living space- the largest space in our universe known to be inhabited by living organisms.About 97 percent of all water on earth is in our oceans, 2 percent is frozen in our ice caps and glaciers, less than 0.3 percent is carried in the atmosphere in the form of clouds, rain, and snow. All of our inland seas, lakes and channels combined add up to only 0.02 percent of earth's water.The Antarctic Ice Sheet is almost twice the size of the United States.Earth's ocean is made up of more than 20 seas and four oceans: Atlantic, Indian, Arctic, and Pacific, the oldest and the largest.

Water is the common link among the five biomes and it makes up the largest part of the biosphere, covering nearly 75% of the Earth’s surface. Aquatic regions house numerous species of plants and animals, both large and small. In fact, this is where life began billions of years ago when amino acids first started to come together. Without water, most life forms would be unable to sustain themselves and the Earth would be a barren, desert-like place. Although water temperatures can vary widely, aquatic areas tend to be more humid and the air temperature on the cooler side.

Most of the water on our planet is in the oceans that cover 71 percent of Earth's surface. Less than 1 percent of all the water is considered freshwater, and most of that is frozen in the polar ice caps. The study of freshwater aquatic ecosystems , limnology, has often been separated from the study of marine systems, oceanography. Although freshwater and marine ecosystems are extremely diverse in structure, all of the plants and animals must live in or on water. The physical constraints and opportunities for life in water, and how all of these living organisms interact with each other in a liquid medium, give a unifying theme to aquatic studies.
