The Saltwater Biome

By Troy Jordan and Sierra Summers

The Ocean

  • 70% of the Earth's surface is covered in ocean water. There are five saltwater biomes: Atlantic Ocean, Pacific Ocean, Indian Ocean, Southern Ocean, and the Arctic Ocean. Since there is so much living underneath the waves that we cannot see, here is a small idea of what the saltwater biome contains...


  • Almost all creatures in the Saltwater biome live near at the top layer of the ocean, (where the sun breaks through.)
  • Maine animals found in the ocean are, whales, sharks, octopus, dolphins, squids, and jellyfish.
  • Some of the largest and smallest creatures live in the ocean.
  • Each creature adapts to the environment in which it lives. *Example: Whales have layers of blubber that help keep them warm in the cold waters.

Climate and Location

  • As you move closer to the equator, the temperature warms and as you get closer the the poles, the temperature cools.
  • The currents of the ocean will effect all coastal areas.
  • Depending on the water's temperature, it will match with the temperature of the wind on land.
  • The average temperature of the saltwater biome is 39 degrees Fahrenheit.
  • Also, the ocean makes up 3/4 of the world.


  • There are three layers of the ocean, the Euphotic, Disphotic, and Aphotic zone.
  • Temperatures may increase or decrease depending on the depth of where you are at in the ocean.
  • The water in the biome is always moving.
  • The pull of the sun and the moon will affect the times of the tide changes as well as their severity.
