; class Aves, order Sphenisciformes)

A family of medium-sized to large, marine birds, most of which have black upper-parts and white under-parts. Their feathers are very small and dense, and some birds have crests above the eye. Their bills are short and stout to long and pointed, their legs short and set well back, with webbed toes. Their wings are modified into paddles which do not fold, and they have short tails. They are flightless and swim well under water, coming to land to breed. They walk upright on land, or slide on their bellies. They feed on fish and other marine animals, and nest in burrows or on the ground. There are six genera, with 18 species, found on the coasts of Antarctica, S. America, S. Africa, Australia, New Zealand, and sub-Antarctic islands.
