企鹅是生活在南半球,而且善于游泳和潜水的海鸟。它隶属于鸟纲、楔翼总目(Impennes)、企鹅目(Sphenisciformes)、企鹅科(Spheniscidae)。企鹅主要分布在南极洲沿岸。寒冷给南极造成一种特殊恶劣的生活环境,使得一般生物无法在那里生活。可是,企鹅在南极附近地区却安然无恙,这有其历史发展上的因素。也有人认为与企鹅具长期绝食能力(达4个月之久),它们在陆地上常常直立行走,并且站在海岸上远眺企望,因而有了“企鹅”的名称。企鹅的英文名称是penguin,penguin导源于拉丁文的penguis,意思是肥 Penguins are seabirds that live in the southern hemisphere and are adept at swimming and diving.

The cold creates a particularly harsh living environment for the Antarctic that prevents the average organism from living there. However, penguins are safe and sound in the vicinity of Antarctica, which has its historical development factors. Others think that with penguins having a long-term hunger strike (up to 4 months old), they often walk upright on land and stand on the shores of the sea looking into their hopes, thus giving them the name “penguin.” Penguin’s English name is penguin, penguin derived from Latin penguis, meaning fat
