The few animals that live on the mainland are birds such as Antarctic terns, grey-headed albatross, imperial shag, snowy sheathbill and the most well known inhabitant of Antarctica, penguins. The inhospitable environment helps to deter predators ; the few predators that hunt on the mainland, including the south polar skua and the southern giant ...
Because animals living in cold climates need to conserve as much heat as possible, Allen's rule predicts that they should have evolved comparatively low surface area-to-volume ratios to minimize the surface area by which they dissipate heat, allowing them to retain more heat. For animals living in warm climates, Allen's rule predicts the ...
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.

On snow, cold-tolerant algae can bloom on the snow surface covering land, glaciers, or sea ice when there is sufficient light. These snow algae darken the surface of the snow and can contribute to snow melt. [18] In seawater, phytoplankton that can tolerate both very high salinities and very cold temperatures are able to live in sea ice.
These two species live on the seafloor from relatively shallow water to depths of 3,000 m (9,800 ft), and can grow to around 2 m (6.6 ft) long weighing up to 100 kg (220 lb), living up to 45 years. [ 23 ] [ 27 ] The Antarctic toothfish lives close to the Antarctic mainland, whereas the Patagonian toothfish lives in the relatively warmer ...
Wildlife park animals cope with winter weather. ... Oxfordshire, said this week was one of its coldest in recent history, with temperatures plummeting to -9 Celsius (16F).
The zoo, which is home to animals from all over the world, has seen temperatures drop below freezing at night. Speaking about the primates, Ms Bryant said: "Obviously they don't enjoy the cold ...
The weather station is in a valley between Oymyakon and Tomtor. The station is at 750 m (2,460 ft) above sea level and the surrounding mountains, at 1,100 m (3,600 ft), cause cold air to pool in the valley: in fact, recent studies show that winter temperatures in the area increase with altitude by as much as 10 °C (18 °F).
