The two Fulmars are closely related seabirds occupying the same niche in different oceans. The Northern Fulmar (Fulmarus glacialis) or just Fulmar lives in the north Atlantic and north Pacific, whereas the Southern Fulmar, (Fulmarus glacialoides) is, as its name implies, a bird of the southern oceans. These birds look superficially like gulls, but are unrelated, and are in fact petrels. The northern species is grey and white with a yellow bill, 43–52 cm (17–20 in) in length with a 102–112 cm (40–44 in) wingspan. The southern form is a paler bird with dark wing tips, 45–50 cm (18–20 in) long, with a 115–120 cm (45–47 in) wingspan
