The sailfish is the fastest animal in the ocean and can swim at a speed of 68 miles per hour while the marlin is the second fastest animal in the ocean swimming at speeds of approximately 49 miles per hour. The cheetah is considered the fastest land animal and can run at speeds of 70 miles per hour
Scientists believe that there are over 1 million species of animals and plants living in the ocean. Some speculate that there are 9 million species that have not yet been discovered.
Animals that live in the ocean include marine mammals such as dolphins and whales and many kinds of marine fish. Crustaceans such as lobsters, crabs and shrimp also live in the ocean, as do mollusks such as squid and octopuses.
Octopuses, jellyfish, sharks, sea stars and sea turtles are a few of the numerous animal species that inhabit the oceans. Since most plants need sunlight to carry out photosynthesis, many underwater plants make their homes close to the shore. Phytoplankton is one of the most common plant types.
The ocean is important to life on Earth because of the role it plays in both the hydrologic cycle and the carbon cycle. The hydrologic cycle, also known as the water cycle or H2O cycle, refers to the relationship that exists between the circulation, evaporation and precipitation of water on the plan
The biggest animal in the ocean, and possibly the largest animal ever to live on Earth, is the blue whale. The maximum recorded weight for a 98-foot blue whale exceeded 209 tons. Longer whales, up to 110 feet, have been seen but not weighed.
Oceans lay claim to about 70 percent of the surface of the earth, and ocean life accounts for 94 percent of living things. Despite this, scientists have yet to explore most of the ocean, as its average depth surpasses 12,400 feet and is mostly cloaked in darkness.
The Indian Ocean, like many of Earth's oceans, serves as home to a diverse number of species, including anenomefish, Great White sharks, bottlenose dolphins, blue whales, sea turtles, jellyfish, stingrays, sea anemones, sea snakes, worms and stonefish. Creatures inhabiting the Indian Ocean range in
Some animals that live in the Southern Ocean include Hoff crabs, sea cucumbers, icefish and starfish. Other animals that live in the Southern Ocean include Antarctic toothfish, Patagonian toothfish, elephant seals, krill and giant squid.
Animal life from the topmost to the lowest oceanic zone ranges from sharks and other fish to deep-sea squid and echinoderms such as the sea pig and sea cucumber. The oceanic or pelagic zone has every form of animal life that lives away from the coastal regions.
