The little penguin (Eudyptula minor) is the smallest species of penguin. It grows to an average of 33 cm (13 in) in height and 43 cm (17 in) in length, though specific measurements vary by subspecies. It is found on the coastlines of southern Australia and New Zealand, with possible records from Chile. In Australia, they are often called fairy penguins because of their small size. In New Zealand, they are more commonly known as little blue penguins or blue penguins owing to their slate-blue plumage. They are also known by their Māori name: kororā.
The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies E. m. variabilis and Eudyptula minor chathamensis are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin is sometimes considered a subspecies, sometimes a distinct species, and sometimes a morph. As the Australian and Otago (southeastern coast of South Island) little penguins may be a distinct species to which the specific name minor would apply, the white-flippered birds indeed belong to a distinct species, although not exactly as originally assumed.
and nuclear DNA evidence suggests the split between Eudyptula and Spheniscus occurred around 25 million years ago, with the ancestors of the white-flippered and little penguins diverging about 2.7 million years ago.
Like those of all penguins, the little penguin's wings have developed into flippers used for swimming. The little penguin typically grows to between 30 and 33 cm (12 and 13 in) tall and usually weighs about 1.5 kg on average (3.3 lb). The head and upper parts are blue in colour, with slate-grey ear coverts fading to white underneath, from the chin to the belly. Their flippers are blue in colour. The dark grey-black beak is 3–4 cm long, the irises pale silvery- or bluish-grey or hazel, and the feet pink above with black soles and webbing. An immature individual will have a shorter bill and lighter upperparts.
