In both polar regions of the Earth, whether southern or northern, the ocean is home to numerous marine mammal species: seals, walruses, whales, to name a few.
Around Svalbard, the most common marine mammals are walruses, ringed and bearded seals, and beluga whales.
Only three land mammals live in Svalbard: the polar bear, the arctic fox and the reindeer — all three perfectly adapted to the harshness of the climate.
Svalbard is home to a great many birds, and what stands out most is not so much the variety of species but rather the sheer numbers within a handful of common ones, such as certain Brünnich's guillemot colonies numbering over 150,000 pairs. Most birds are migratory, and the only one to reside in the archipelago year-round is the Svalbard rock ptarmigan.
