The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
In addition to providing many benefits to the natural world, marine ecosystems also provide social, economic, and biological ecosystem services to humans. Pelagic marine systems regulate the global climate, contribute to the water cycle, maintain biodiversity, provide food and energy resources, and create opportunities for recreation and ...
The global classification system Marine Ecoregions of the World—MEOW was devised by an international team, including major conservation organizations, academic institutions and intergovernmental organizations. [1] The system covers coastal and continental shelf waters of the world, and does
Marine organisms such as clams and crabs living in this zone are called benthos. Just above the benthic zone is the demersal zone. Just above the benthic zone is the demersal zone. Demersal fish can be divided into benthic fish , which are denser than water and rest on the bottom, and benthopelagic fish , which swim just above the bottom.
One way of mapping terrestrial (land) biomes around the world. A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1] [2] Biomes may span more than one continent.
Marine biologists divide the intertidal region into three zones (low, middle, and high), based on the overall average exposure of the zone. [2] The low intertidal zone, which borders on the shallow subtidal zone, is only exposed to air at the lowest of low tides and is primarily marine in character.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [1] The marine environment supports many kinds of these habitats.
