Aquatic Biomes

  • Aquatic biomes are biomes found in water.
  • Water covers 70 percent of Earth’s surface, so aquatic biomes are a major component of the biosphere.
  • However, they have less total biomass than terrestrial biomes.
  • Aquatic biomes can occur in either salt water or freshwater.
  • About 98 percent of Earth’s water is salty, and only 2 percent is fresh.
  • The primary saltwater biome is the ocean. Major freshwater biomes include lakes and rivers.
