The ocean covers nearly three-fourths of the globe and is home to many extremes from its surface to its depths. We've picked some of the most extreme facts the ocean has to offer. Happy sailing!

  1. (large) creature: The blue whale is Earth's creature, and probably the animal that has ever lived on this planet. It can measure nearly 100 feet (30.5 m) long and weigh 180 metric tons. Its heart is as big as a Volkswagen Beetle and its body is larger and heavier than the estimates for any known dinosaur.

  2. (large) living structure: Dwarfing even the mighty blue whale, the living structure is the Great Barrier Reef, a mass of coral off the northeastern coast of Australia that extends some 1,250 miles. The reef supports an amazing array of life that includes approximately 2,000 species of fish.

  3. (deep) point: The point on Earth is located in the Mariana Trench southwest of Guam. This point, the Challenger Deep, is estimated to be 36,198 feet (11 km) deep. That's enough to hold Mount Everest with more than 6,000 feet (1,800 meters) to spare.

  4. (tall) wave: In 1933 sailors on a United States naval ship recorded a 112-foot-tall (34 meters) wave in the Pacific Ocean.

  5. (small) fish: The female of the pygmy goby, found in the Philippines, measures less than one-quarter of an inch (6 mm) at full size.

  6. (scary, large) embrace: The giant squid, the world's invertebrate, grabs its lunch with tentacles up to 40 feet long and gazes upon its prey with eyes the size of basketballs. Fortunately, giant squids reside in the deep sea and there is no evidence that one has ever attacked a person.

  7. (long) migration: The gray whale migrates more than 10,000 miles (16,000 km) each year, tracing a path between the Bering Sea and lagoons off the coast of northern Mexico.

  8. (toothy) smile: Some sharks may grow, lose, and replace as many as 30,000 teeth in their lifetime. Several rows of replacement teeth continually develop behind the teeth a shark actually uses.

  9. (long) mountain range: The mid-ocean ridge wraps around the globe's oceans like seams on a baseball to create a continuous chain of mountains over 40,000 miles long.

  10. (valuable, important) commodity: The ocean is estimated to contain 10 billion tons of gold. Even at the bargain price of $200 per ounce, that comes to $640 quadrillion. But because nobody has figured out how to collect all of that gold, the ocean's economic products today include fish, salt, and offshore oil deposits.
