There are 400 known fish species living in Arctic seas and adjacent waters, most living on or near the bottom. So, based on global fisheries and the overall biodiversity of coral reef ecosystems, the Pacific Ocean wins for most marine life.
Where is marine biodiversity highest?
A new study finds that sea surface temperature, as well as the size and variety of habitats are the main factors responsible for the proliferation of marine life in the Coral Triangle – the most biologically diverse marine region in the world.
Which sea contains the world’s richest marine biodiversity?
Introduction. Why is the Central Indo-Pacific (CIP) so diverse? This region, including the coral reefs of Southeast Asia and Australia, contains more species than any other in the world’s oceans, across diverse taxa .
Does the ocean have the most biodiversity?
The world’s oceans contain somewhere between 500,000 and 10 million marine species. bacteria, other microbes and viruses. Much of the biodiversity in the ocean, particularly in the deep sea and in the microbial ocean, is unknown, and up to 2,000 new species are described per year.
Where is the most biodiversity found on Earth?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
What is the richest sea on earth?
Covering 169.2 million square kilometers, it is larger than all of the Earth’s land area combined. The Pacific contains 25,000 islands (over half the islands in the world), most of which are south of the equator. The Pacific’s greatest asset is its fish.
Which ocean zone has the least biodiversity?
The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round.
How much biodiversity is in the oceans?
Oceans cover 70% of our planet and represent over 95% of the biosphere.
Which ocean basin has the most coral reefs?
The Pacific Ocean has the most coral species.
Generally, there are about twice as many coral species in Pacific Ocean reefs as in Atlantic Ocean reefs.
Is there more sea than land?
The more granite there is, the more continent there is, and the more of the Earth’s surface rises above the ocean basins. Water fills the basins. Right now, there is more basin than continent, and so more ocean surface than land surface.
