Ocean Biome

The Ocean Biome

Approximately 70% of the world is ocean. Many believe life derived from the ocean and was formed 3 million years ago. The 5 oceans are the Atlantic Ocean, Pacific Ocean, Indian Ocean, Southern Ocean, and the Arctic Ocean. The ocean covers the whole world and is home many plants and animals. The Ocean also has it’s own special weather pattens and many geographical locations.

Animals in the Oceans


There are many animals in the ocean such as whales, sharks, octopus, dolphins, sea cucumbers, and squids. This is just a handful of the thousands of animals the ocean. The ocean is home to the most diverse group of species. Some animals like the whale shark or the blue whale eat krill and plankton whereas animals like sharks and dolphins eat other fish. Some ocean animals are even herbivores and live in shallow water so they can eat sea plants and some types of algae. Most ocean animals have gills to breathe underwater although some can just hold their breath for a very long time and will come to the surface every couple of hours for a breath. Fish come in every size. from to the size of the tip of your finger to 42 ft. in length. The ocean is home to a diverse range of animals.


The ocean is home to many plants even though they are underwater they can grow and this is how they grow. Sunlight can extend down into the ocean up to 660 feet. In murky waters it only extends 50 feet. This zone is called the sunlit zone but it is also called the euphotic zone or epipelagic zone. Plants grow in this zone where they can get sunlight, below is a diagram. Some of the most important plants are phytoplankton, kelp, algae, sea grasses, and sea mats. Phytoplankton are small plants which clean carbon dioxide from the air, there are hundreds of thousands of species of phytoplankton. Kelp are enormous plants that grow up to 90 feet tall and grow in huge underwater forests.Like terrestrial forests, kelp forests grow in layers, with a canopy and several layers of understory plants. Seagrass and sea mats basically provide food and shelter for small animals. Algae are photosynthetic eukaryotes that are either unicellular, colonial, or multicellular. As you can see there are many plants in the ocean biome and are very helpful to the environment.


The ocean biome is the largest biome. It covers 71% of the whole world and still 95% of the underwater is unexplored. Coral reefs all around the world are found in warm shallow waters such as in the Great Barrier Reef. Corals are the dominant organism in coral reefs. They are composed of algae and tissues of animal polyp. The Great Barrier Reef is on the coast of Australia. Surrounding the Great Barrier Reef is the Coral Sea. From Cairns, Australia on the coast you can access the Great Barrier Reef and its mangroves, rocky reefs, open ocean and the deep sea floor. Snorkeling, diving and fishing are things to do, or just relax and enjoy the Great Barrier Reef. Malanda, Atherton, and Bird World Kuranda are all attractions to see at the Great Barrier Reef. Also, landmarks like Lady Elliot Island Lighthouse on Lady Elliot Island, Sandy Cape Lighthouse on Fraser Island, and Maheno Wreck also on Fraser Island are great places to enjoy as well.


An Oceanic climate is the climate typical of the west coasts, and is generally warm. It has warm summers and cool winters. The Ocean has a relatively narrow annual temperature range. It typically lacks a dry season. Precipitation is more evenly dispersed throughout the year. Precipitation is both adequate and reliable throughout the year in oceanic climates, except in certain tropical highland areas. The average temperature of all oceans is about 39 degrees Fahrenheit but the oceans in different parts of the world can have very different climates. Tropical oceans near the equator are warm and clear on the surface. The best time to go to the Great Barrier reef is in the spring or summer.
