An Adélie penguin encountering a human during the Antarctic summer. Penguins have no special fear of humans and will often approach groups of people. This is probably because penguins have no land predators in Antarctica or the nearby offshore islands. They are preyed upon by other birds like skuas, especially in eggs and as fledglings.
The great auk (Pinguinus impennis), also known as the penguin or garefowl, is an extinct species of flightless alcid that first appeared around 400,000 years ago and became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus.
The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
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.
The flightless penguins are almost all located in the Southern Hemisphere (the only exception is the equatorial Galapagos penguin), with the greatest concentration located on and around Antarctica. Four of the eighteen penguin species live and breed on the mainland and its close offshore islands.
These animals have originated with these adaptations, and animals that live in these regions are accumulating adaptations to be able to live in this type of environment. Some of these adaptations may be to be big and insolated, have a lot of fur, and to be darker. Also, many animals live in groups to be able to protect themselves from the cold.
The arctic tundra often lacks sunshine. Summer days last 24 hours, yet the sun remains low on the horizon. During the winter, the opposite occurs, and the entire landscape is dark.
