The Ocen Biome

The ocean holds the largest of Earth’s biomes. It covers 70% of the planet’s surface.

Life in the ocean is diverse. The smallest creatures that call the ocean home are so tiny that they can only be seen with a microscope. The largest creatures are blue whales, which can be as much as 34 meters (110 feet) long. There are many different ways to live in the ocean, too. Some animals travel huge distances through ocean water. Others stay in the same place on the ocean floor their entire lives. Some burrow beneath the sand while others float near the surface.

The ocean is not the same everywhere. There are many different ecosystems within the ocean depending on conditions such as the water temperature, the amount of sunlight that filters through the water, and the amount of nutrients.

sunlight breaks through the top layer of ocean water. It can make its way as deep as 200 meters (656 feet). Almost all marine life (about 90%) lives within this top, sunlit layer of the ocean. There,phytoplankton, algae, and plants like seagrass make their own food through the process of photosynthesis, and are the start of most marine food chains


The temperature of ocean water varies depending on its location. Water near the polar regions is colder than water near the equator. Water that is deep in the ocean is colder than water that is near the ocean surface. Many animals and other organisms can only survive at certain temperatures. Others are able to survive at a range of temperatures and can live in more places in the ocean.

Plant life


  • Phytoplankton is the most abundant plant that exists in the ocean. Phytoplankton is a single celled plant that includes diatoms. They are free-floating plants living at the surface of the water. They usually exist in cooler waters where nutrients are abundant due to upwelling.


  • Kelp is an ocean plant that is located near the shore line where it holds onto rocks with roots called hold fasts. Kelp can grow extremely long, remaining upright with gas bladders that are attached to the leaf.


  • Seaweed lives in the intertidal zone of the oceans. Seaweed is rooted and can usually be found in water up to 40 meters deep, but may be found deeper in very clear water. We use seaweed as food and in products such as lotions, soaps and toothpaste.

Frilled Shark

Humans rarely encounter frilled sharks, which prefer to remain in the oceans' depths, up to 5,000 feet (1,500 meters) below the surface. Considered living fossils, frilled sharks bear many physical characteristics of ancestors who swam the seas in the time of the dinosaurs. This 5.3-foot (1.6-meter) specimen was found in shallow water in Japan in 2007 and transferred to a marine park. It died hours after being caught.

Mosaic Jellyfish

A mosaic jellyfish floats serenely in the waters of the Coral Sea, about 100 nautical miles from Cairns, Australia. Jellyfish are ubiquitous in the Earth’s oceans. They can thrive in warm water and cold, along coastlines or out in the deep. Their bodies are about 95 percent water. And though they have no brains, jellyfish have somehow been smart enough to survive for over 500 million years.

Common Octopus

The common octopus is anything but ordinary. This most intelligent of the invertebrates uses an amazing suite of abilities to avoid predators like sharks, eels, and dolphins. A master of camouflage, the octopus can change color and shape to remain unseen, and release a “smoke screen” of black ink when spotted. Even if an octopus has been nabbed, the game isn’t over—it can simply shed an arm to escape trouble and regrow the appendage later.
