Chinstrap penguin. Penguins are birds in the family Spheniscidae in the monotypic order Sphenisciformes. [1] They inhabit high-productivity marine habitats, almost exclusively in the Southern Hemisphere; the only species to occur north of the Equator is the Galapagos penguin.
In 2003 there were an estimated 1,351 penguins [22] and as of 2018 there are around 1,200 mature penguins left. The Galapagos penguin is currently one of the rarest penguin species, [23] next to another penguin species, the yellow-eyed penguin. The population size on average is about 1,500 individuals per year, depending on the climate events. [24]
Sphenisciformes (from the Latin for "wedge-shaped") is the taxonomic order to which the penguins belong.
