While they were in close geographical proximity to the ostrich, their closest living relatives are kiwi, suggesting that ratites did not diversify by vicariance during the breakup of Gondwana but instead evolved from ancestors that dispersed more recently by flying.

The only non-bird vertebrates on the island are seals, specifically the southern elephant seal and Antarctic fur seal, which both breed on the island. In 1998–99, there were 88 elephant seal pups and 13,000 fur seal pups at Nyrøysa. Humpback whale and killer whale are seen in the surrounding waters. Bouvetøya is one of three dependencies of Norway.
