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.
Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
The great auk was one of the 4,400 animal species formally described by Carl Linnaeus in his eighteenth-century work Systema Naturae, in which it was given the binomial Alca impennis. [16] The name Alca is a Latin derivative of the Scandinavian word for razorbills and their relatives. [ 17 ]
Tourism, fishing and research are the main human activities in and around Antarctica. During the summer months, about 5,000 people reside at research stations, a figure that drops to around 1,000 in the winter. Despite the continent's remoteness, human activity has a significant effect on it via pollution, ozone depletion, and climate change.
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.
Bergmann's rule - Penguins on the Earth (mass m, height h) [1] Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions.

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.
