Adaptive features of four animals in polar region

Context As students approach this Animal Adaptations lesson, bear in mind that, according to research, most lower elementary school students are still forming a basic understanding of how animals survive in their respective environments.

Adaptive features of four animals in polar region

The former is more of a rocky dweller, while the latter prefers wetter areas. Lemmings survive the cold primarily for two reasons. First, they are furry, very furry. In fact, from a distance, they can appear almost round in shape. Kind of gives new meaning to the term "fur ball.

In the winter, they burrow down into the snow. The snow traps the air, and it becomes an excellent insulator. Sadly for the lemming, many arctic predators find these little guys to be tasty treats, all that long fur notwithstanding.

As a result, time spent in snow tunnels also keeps them safe. Lemmings Wikipedia Commons 5. However, they do share a common approach to surviving the arctic cold - they hang out in groups. In fact, the hares do so in a big way. There may be literally hundreds of them huddling together for both warmth and protection.

When a noise is heard they act a little like crooks after a robbery; they scatter in all directions. Arctic Ground Squirrels These particular ground squirrels probably hang out in their dens laughing as they think about all those hares huddling out in the cold. Before the arctic winter arrives, they wisely line their burrows with great insulators like Musk Ox hair, leaves, and lichens.

While they sleep, their body temperature drops to just a tad above freezing, and their heartbeat slows way down.

This particular ground squirrel still does use insulators, including the ground itself. It also adapts to the cold by slipping into a virtually vegetative state.

Unlike the snowy owl, arctic hare, article fox, and many other arctic animals that blend into the white snow, this massive beast could care less. His fur may be dark, but it is also warm, for a number of reasons: It is thick It is very long It has hollow hairs Air is a wonderful insulator, and the hollow hairs of the Musk Ox keep the air warmed by body heat close by where it is needed.

And, when it comes to this citizen of the tundra, there is a whole lot of that hair. It hangs almost to the ground, creating a tent of sorts. The area directly beneath the animal is kept warm. That layer of warm air adds to comfort.

Finally, as is true of many arctic animals, the fur is very thick.

Relatively warmer air is not only trapped inside the hollow hairs, but all around them as well. During spells of extreme cold, they huddle together.

Collectively, all the body heat they emit helps to warm the surrounding air just a little. Some of us run around in the cold to stay warm; it appears that the sedentary Musk Ox is not too keen on that idea.

That huddling is for protection as well. Wolves are always on the prowl for smaller calves. Therefore, the adults form a circle around their young, with their prominent horns pointing outward for protection. Like the Polar Bear, the Musk Ox has one defense after another against the arctic cold, helping them to maintain their core temperature.

Tundra and Arctic Wolves Compared to other species of wolves, these inhabitants of the far north have evolved some rather interesting ways to minimize heat loss. Their legs are shorter, their ears are smaller and more rounded, and they have a shorter muzzle.Answers many questions about the polar bear and has reliable information from Seaworld Polar Bear pages.

Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere, and it contains land and the islands that surrounds it.
