| | Digimorph - Eudyptula minor (Little Penguin) |
 | | Penguins in general (see also Spheniscus demersus, the jackass penguin, Aptenodytes forsteri, the emperor penguin, and Pygoscelis adeliae, the Adelie Penguin) are highly derived avians with no clear relatives among other living birds, although most studies suggest that they are related to one among a number of seabirds. |
 | | Penguins are entirely aquatic and have evolved numerous associated adaptations, including specialized salt glands (which allow them to drink salt water), extremely flattened wing bones, and a unique system of water-proof feathers (Davis and Renner, 2003). |
 | | Little penguins, although not listed as threatened or endangered, are in decline due to extreme predation by introduced mustelids (ferrets, stoats, and weasels) and dogs, as are many flightless New Zealand birds. |
