While low in species diversity the animals present in Svalbard are highly abundant, especially in the summer. The Svalbard reindeer, the Arctic fox and polar bears are just some of the species adapted for the extreme conditions in Svalbard. With a population of more than 3000, there are times when the polar bears outnumber humans. Strongly tied to sea ice and proficient swimmers this great predator can easily be viewed from the comfort and safety of the deck of a large boat cruise. Ringed seals, bearded seals, and walruses abound in populations of thousands. Cruises are also great way to capture narwhals, beluga whales and even the incredibly rare bowhead whale almost hunted to extinction during the whaling era.
