So exactly what is an ocean biome? The marine biome description all begins with the fact that is an entire environment that is immersed amongst saltwater, in other words within our oceans. Marine biomes each with their own characteristics are found in all the oceans in the world and make up what is considered to be the largest biome in the world. The marine biome is home to thousands of animal species from tiny microorganisms to some of the largest mammals in the world, it also contains many varieties of plant species all creating a thriving underwater ecosystem.

Some more marine biome information that can help you understand what you may find there includes many different characteristics in which a marine biome can be recognized. Oceans near and far from the equator are all considered to have their very own marine biome filled with many different species according to the climate surrounding the oceans and the nutrients it can provide. The temperature within the ocean according to its location has a great impact on what kind of marine life can be found there. In order to be considered a marine biome, the water needs to be made up of around 96 percent fresh water and around 4 percent of dissolved compounds or salinity which is the saltiness of the water. The amount of salt present in each ocean is dependent on a number of variables including its depth, biological activity, and erosion. Sunlight is something that goes hand in hand with the marine biome as this is one of the primary sources for keeping the inhabited organisms healthy and able to retrieve the correct amount of nutrients for survival.


There is not much of a variety of plant species found in the marine biome open ocean, however, the main species that can be found in seaweed, this is again because of the sunlight which allows them to photosynthesize and reproduce, expanding its population within the ocean. Algae is also commonly found in the marine biome in which there are hundreds of different types and although it is not exactly considered a plant it acts of the same process of photosynthesis which helps to feed many fish species and keep the oceans cycle healthy and thriving.


The open ocean biome is home to thousands upon thousands of different animal species, even scientists are still discovering more and more each year, these animal species range from the smallest microorganisms to some of the largest on earth including the mammoth whale. However, most of the marine life lives in the higher parts of the oceans as this is where the most sunlight can e retrieved. There are also numerous types of plankton that can be found in the open ocean, these are tiny animals, protists, plants, or bacteria that can be seen floating in conjunction with the currents and tides. These plankton species are one of the most important aspects of the marine biome animal life as they sit directly at the bottom of the food chain and are the foundation of every marine life ecosystem. Of course one of the most prominent animals that can be found in the open oceans is fish. There are thousands of different species of fish some can be found alone and other swimming is massive schools, each with their own purpose and characteristics. Other animals that can be found in the open oceans include dolphins, octopus, squid, and sharks.

The temperature of the marine biome all depends on its exact location, the closer it is to the equator the warmer it becomes, however, the average temperature is around 4 degrees celsius. The species found within the marine biome are directly affected by the climate experienced within the location. The ocean also faces some extreme weather conditions including hurricanes and typhoons however many of the animal species such as fish, seals, and plankton are said to have adapted to these harsh changes in tides and currents and affectively migrate to safer parts of the oceans. Climate change is also impacting marine life as the higher the temperature becomes the more marine life is lost and also impacts coral by bleaching it causing it to lose life and sustainability that the ocean and marine life within it desperately needs.


definition of marine biome
  • The marine biomes cover around 70 percent of the earth’s surface.
  • Marine biomes are divided into three different types: Oceans, Coral Reefs, and Estuaries.
  • Around 90 percent of all life on earth lives in the oceans.
  • Most of the life found in the marine biome lives in the first 200 meters.
  • Most of the ocean has not been explored or discovered.
  • 200 000 species have been identified as inhabitants of the ocean.
  • Climate change and pollution are extreme threats to the sustainability of marine life.

As you can see there is so much to be discovered about the marine biome and its fascinating and extraordinary life.
