Are there arctic penguins

Adept swimmers that chase after krill, fish, and squid, penguins have no need to fly thanks to a lack of natural predators on the Antarctic ice.

Read about penguin mega-colonies discovered in Antarctica. In the ocean, though, penguins most contend with leopard seals , formidable hunters that specialize in warm-blooded prey.

Dubbed the unicorn of the sea due to their long, spiraled tooth, narwhals are a beloved Arctic animal that, like other porpoise species, can be spotted swimming in groups of dozens or even hundreds of animals. The narwhal is a year-round Arctic resident, summering in ice-free coastal waters. When faced with impenetrable coastal ice, these marine mammals move offshore, into deeper waters, to feed under shifting pack ice.

They use cracks and openings in the ice to breathe. Read more about the mystery of the sea unicorn. The predators, which have a life expectancy of at least years , eat whatever they catch or scavenge, from unwary fish or seals to carcasses of polar bears or caribou. The icefish species Chaenocephalus acteratus are also notable as the only vertebrates with no red blood cells; their white blood gives them a ghostly appearance. Read about a new species of see-through fish discovered in Antarctica.

Orcas , or killer whales, live in many oceans worldwide, including those around Arctic and Antarctica. About 70, orcas live in southern waters, where they specialize in different foods. Eisert has observed Type C orcas swimming at least a mile under a sheet of ice—a risky behavior for air-breathers.

See exclusive footage of rarely seen Type D orcas. Its black tail gives it a tuxedo-like appearance. Travel with us to Antarctica to see these animals and more. In the Arctic, on the other hand, seals are aware of their place on the food chain—a notch below terrestrial predators like polar bears, foxes, wolves, and humans. In the Arctic, you can't walk closer than about feet to a ringed seal before it flees.

Weddells also birth their pups right on the ice, while ringed seals hide them in a snow-covered lair. Emperor penguins are the largest of all penguins. An average bird stand about 45 inches tall. Penguins are often called 'flippered flyers' because of their effortless movement through the water. This bird is not able to fly; its wings are developed for swimming rather than flying. Underwater, they can reach speeds of up to 15 to 25 miles per hour.

Emperor penguins can reach depths of up to to 1, feet! A group of chicks are called creches, and are left when the adults fish. A group of penguins is called a colony. The average penguin weighs about 88 pounds. That's a lot of insulation! Increasingly scientists and policy-makers speak of the Antarctic as no longer remote in any sense. And vice versa. What remains to be understood is how rising temperatures, and the rise is not uniform across the Antarctic, is having varied consequences for ice cap stability and biodiversity.

What to do? The governance of the Antarctic is so much more complicated than it once was in the s. In the late s, the Antarctic Treaty stood largely untroubled by other kinds of international legal entanglements.

This is no longer the case. The Antarctic is ensnared in a complex mix of legal regimes involving terrestrial and marine environments. The Antarctic is no longer exceptional in that regard, and that troubles claimant states and even non-claimants such as the United States. The good news is that all the parties working in the Antarctic accept that there should be no mineral exploitation.

This ban is in place for at least three decades. There is no evidence that mining is coming any time soon. The Arctic is on the front line in that regard. The bad news is two fold. Scientists worry that the Antarctic ice sheet is being destabilized by ongoing climate change. This will have consequences for the region and the wider world. And political co-operation might be undermined if states and other stakeholders continue to make money from Antarctic related activities.

When they return to the colony, they carry a stomach full of food to regurgitate to their young. Polar bears occasionally inter-breed with grizzly bears creating a hybrid bear known as a pizzly bear, prizzly bear or grolar bear. The existence of these hybrid bears in the wild was only confirmed in , but they are expected to become more common as polar bears extend their hunting grounds due to scarcity of pack ice.
