Fun Facts:

The oceans occupy nearly 71% of our planet's surface making it the largest biome, with lots of fun and interesting facts here are a few:

  1. More than 97% of all our planet's water is contained in the ocean
  2. The top ten feet of the ocean hold as much heat as our entire atmosphere
  3. The average depth of the ocean is more than 2.5 miles
  4. The oceans provide 99 percent of the Earth's living space- the largest space in our universe known to be inhabited by living organisms
  5. More than 90% of this habitat exists in the deep sea known as the abyss
  6. Less than 10% of this living space has been explored by humans.
  7. The Monterey Bay Submarine Canyon is deeper and larger in volume than the Grand Canyon
  8. The Antarctic ice sheet that forms and melts over the ocean each year is nearly twice the size of the United States
  9. The average temperature of the oceans is 2ºC, about 39ºF
  10. Water pressure at the deepest point in the ocean is more than 8 tons per square inch, the equivalent of one person trying to hold 50 jumbo jets.
  11. The worlds oceans contain nearly 20 million tons of gold
  12. The color blue is least absorbed by seawater; the same shade of blue is most absorbed by microscopic plants, called phytoplankton, drifting in seawater
  13. The blue whale, the largest animal on our planet ever (exceeding the size of the greatest dinosaurs) still lives in the ocean; it's heart is the size of a Volkswagen
  14. The gray whale migrates more than 10,000 miles each year, the longest migration of any mammal
  15. The Great Barrier Reef, measuring 1,243 miles, is the largest living structure on Earth. It can be seen from the Moon.


16.The oceans occupy nearly 71% of our planet's surface

17. There are two types of oceans, saltwater, and freshwater.

18. Natural events such as hurricanes, and tsunamis occur.

19. Growing season last all year round, but there are different season depending on the species.

20. Sand covers the ocean floor.

21. Ocean Biome layers:

More than 90 percent of the trade between countries is carried by ships and about half the communications between nations use underwater cables
  1. More oil reaches the oceans each year as a result of leaking automobiles and other non-point sources than was spilled in Prince William Sound by the Exxon Valdez
  2. Fish supply the greatest percentage of the world's protein consumed by humans
  3. Most of the world's major fisheries are being fished at levels above their maximum sustainable yield; some regions are severely overfished
  4. Eighty per cent of all pollution in seas and oceans comes from land-based activities.
  5. Three-quarters of the world's mega-cities are by the sea
  6. Death and disease caused by polluted coastal waters costs the global economy US$12.8 billion a year. The annual economic impact of hepatitis from tainted seafood alone is US$7.2 billion.
  7. Plastic waste kills up to 1 million sea birds, 100,000 sea mammals and countless fish each year. Plastic remains in our ecosystem for years harming thousands of sea creatures everyday.
  8. Tropical coral reefs border the shores of 109 countries, the majority of which are among the world's least developed. Significant reef degradation has occurred in 93 countries.
  9. Although coral reefs comprise less than 0.5 per cent of the ocean floor, it is estimated that more than 90 per cent of marine species are directly or indirectly dependent on them.
  10. There are about 4,000 coral reef fish species worldwide, accounting for approximately a quarter of all marine fish species.
  11. Nearly 60 per cent of the world's remaining reefs are at significant risk of being lost in the next three decades.
  12. The major causes of coral reef decline are coastal development, sedimentation, destructive fishing practices, pollution, tourism and global warming.
  13. Less than one half a per cent of marine habitats are protected -- compared with 11.5 per cent of global land area.
  14. Although there are some treaties that protect ocean-going species such as whales, as well as some fisheries agreements, there are no protected areas in the High Seas.
  15. More than 3.5 billion people depend on the ocean for their primary source of food. In 20 years, this number could double to 7 billion.
  16. Populations of commercially attractive large fish, such as tuna, cod, swordfish and marlin have declined by as much as 90 per cent in the past century.
  17. Each year, illegal longline fishing, which involves lines up to 80 miles long, with thousands of baited hooks, kills over 300,000 seabirds, including 100,000 albatrosses.
