List of marine ecoregions (WWF) Wikipedia
This is a list of marine ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions.
The WWF/Nature Conservancy scheme for marine ecoregions 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. The marine realms are subdivided into 62 marine provinces, which include one or more of the 232 marine ecoregions. The WWF/Nature Conservancy scheme currently encompasses only coastal and continental shelf areas; ecoregions of the deep oceans have not yet been delineated.
