Why is there no penguin in the Arctic
4hw.com.cn: penguins have been seen by many friends. We all know that penguins live in the extremely cold area of Antarctica. A friend asked, the Arctic is also extremely cold. Why is there no penguin in the Arctic? Now with this question, let's take a look.
First of all, penguins have never lived in the Arctic for a long time.
Penguins were born in the southern hemisphere. The earliest known Penguin fossil was in New Zealand 62 million years ago. Moving from the south pole to the north pole is through hot tropical waters, which is too difficult for penguins without planes and air conditioning. Basically no penguin can tolerate temperatures above 30 degrees.
In fact, penguins have been making great efforts to march north. About half of the penguin species actually live in the southern temperate zone. The famous 213 penguin, the Galapagos penguin, even marched to the equator and became the only penguin species across the northern and southern hemispheres (although there are only dozens of penguins in the North of the equator), but it was only exposed to the light of the Peruvian cold current You can't live without it.
There used to be a kind of bird near the Arctic called Pinguinus impennis, a little like penguin. Although Neanderthals began hunting them 100000 years ago, the real threat is that a large number of Europeans have hunted them since the middle ages, plucking their hair to make pillows. When the great puffin became endangered, its specimens and eggs became a rare collection. The last known pair of great auks were strangled and their eggs crushed on July 3, 1844. Later, in 1852, a lone great puffin was seen in Newfoundland. This was the last time that human beings saw it alive. The great auk has nothing to do with the penguin, the former is the shorebird, the latter is the penguin.
In addition, penguins have to stay on land for a long time during their brooding period, which is very unfavorable to resist the attack of polar bears. So even if penguins cross the tropics, they may not be able to survive in the Arctic.
However, although there are no penguins to live long, humans have indeed found a single penguin in the northern hemisphere, and not in the Zoo & hellip; & hellip; more famous is that on July 18, 2002, fishermen caught a Humboldt penguin in Alaska, 55 degrees north latitude, about 10000 kilometers away from its origin. It may have escaped from a nearby zoo, but it may have swam by itself or accidentally brought by a fishing boat.
