Procellariiforms range in size from the very large wandering albatross, at 11 kg (24 lb) and a 3.6-metre (12-foot) wingspan, to tiny birds like the least storm petrel, at 20 g (0.71 oz) with a 32-centimetre (13-inch) wingspan, [27] and the smallest of the prions, the fairy prion, with a wingspan of 23 to 28 cm (9.1 to 11.0 in).

Mollymawks have the largest range in size of all the albatross genera, as their wingspans are 180 to 256 cm (71–101 in). [9] Mollymawks have what has been described as gull -like plumage , with dark black backs, mantle and tails and lighter heads, underwings and bellies.
They are large, black-and-white or completely black, with long wings and deeply forked tails. The males have colored inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.
