Seamounts often project into the shallower zone more hospitable to sea life, and thus provide habitats for marine species that are not found in the surrounding ocean. In addition to simply providing a bottom in this zone, the seamount may deflect currents and create upwelling. This brings nutrients into the photosynthetic zone, producing islands of food production in otherwise desert-like open ocean. Seamounts may thus be vital stopping points for migratory animals. There is also evidence that some animals, particularly the large whales, may use seamounts as navigational aids.
