  Norway has a larger number of different habitats than almost any other European country. There are approximately 60,000 species in Norway and adjacent waters (excluding bacteria and viruses). The Norwegian Shelf large marine ecosystem is considered highly productive. The total number of species include 16,000 species of insects (probably 4,000 more species yet to be described), 20,000 species of algae, 1,800 species of lichen, 1,050 species of mosses, 2,800 species of vascular plants, up to 7,000 species of fungi, 450 species of birds (250 species nesting in Norway), 90 species of mammals, 45 fresh-water species of fish, 150 salt-water species of fish, 1,000 species of fresh-water invertebrates, and 3,500 species of salt-water invertebrates. About 40,000 of these species have been described by science. The red list of 2010 encompasses 4,599 species. Norway contains five terrestrial ecoregions: Sarmatic mixed forests, Scandinavian coastal conifer forests, Scandinavian and Russian taiga, Kola Peninsula tundra, and Scandinavian montane birch forest and grasslands.
  
  Seventeen species are listed mainly because they are endangered on a global scale, such as the European beaver, even if the population in Norway is not seen as endangered. The number of threatened and near-threatened species equals to 3,682; it includes 418 fungi species, many of which are closely associated with the small remaining old-growth forests, 36 bird species, and 16 species of mammals. In 2010, 2,398 species were listed as endangered or vulnerable; of these 1,250 were listed as vulnerable (VU), 871 as endangered (EN), and 276 species as critically endangered (CR), among which were the grey wolf, the Arctic fox, and the pool frog.
  
  The largest predator in Norwegian waters is the sperm whale, and the largest fish is the basking shark. The largest predator on land is the polar bear, while the brown bear is the largest predator on the Norwegian mainland. The largest land animal on the mainland is the elk (American English: moose).
