By 2010, scientists say they may find more than 2 million different species of marine life.
So far, the Census of Marine Life comprised 15,304 species of fish and 194,696 to 214,696 species of animals and plants, estimated to be roughly 10 percent of the world's total.
The census is adding about 150 to 200 species of fish and 1,700 species of animals and plants each year.
The scientists said they believe the oceans that extend across 70 percent of Earth's surface hold about 20,000 species of fish and up to 1.98 million species of animals and plants.
But still now we are struggling to live each other although all of us are in same kind.
