A Journey Through the Tundra
Transcript of A Journey Through the Tundra
Welcome to the Tundra
Brrrr! It's cold out here. We are in the Arctic Tundra, or Polar Desert. This is one of the Extreme Environments of the world.
How Does This Creature Stay Warm in These Cold Temperatures?
You Want to Know? I'll tell you! After all, I am a Wolverou expert. Wolverou Adaptation #1.
What Are Its Adaptations?
Let's Start Our Journey Through the Tundra! Hope You Stay Warm!
Wait, I think I saw something move behind that bush! What is it?
Arctic Wolf Ears!
A Journey Through the Tundra
By Cassidy and Vanessa
Some reasons that this is such an extreme environment are sub-zero temperatures, short summers lasting about 50-60 days, wind reaching highs of 50-60 kilometers an hour or higher, and the low of precipitation makes the tundra very dry. The Arctic Tundra is located north of Canada, Russia, Norway, and Iceland on the northern tip of the world. The Arctic Tundra is also where Santa Claus lives.
Easy! Using many different arctic animal adaptations, this Wolverou can stay warm in freezing temperatures! This animal is also meant to be able to breath in the cold arctic air through it's mouth and it's nose. The Wolverou can smell, hear, taste, see, and touch. It can move all parts of its body in order to defend itself, walk, and eat. Walking is easy for the Wolverou with the adaptation of a special kind of hare's feet.
The Wolverou has caribou antlers so that it can fight any threatening predators. The Wolverou will lower his/her head and charge toward the predator. The antlers stick out from the Wolverou head, giving themselves a safe distance from the predator. The antlers typically have two separate groups of points, a lower and upper.
Arctic wolf ears help this amazing Wolverou stay warm because of it's smaller ears. An arctic wolf can hear up to 6 miles away in forests and 10 miles in open areas, including some high pitched sounds humans aren't able to hear. Even when an arctic wolf sleeps, this particular wolf’s ears stand straight up so it can catch sounds made by other animals at all times. This helps the wolf catch prey, and let it know when danger is near. These wolves can easily tell what direction sound is coming from by turning their ears side to side. The direction the ears are pointing when the sound is loudest tells the wolf which direction the sound is coming from. Their hearing ability is a great technique used for hunting and communicating with other wolves.
The Wolverou has a wolverine head to eat whatever they can kill. The powerful jaws and large teeth of the wolverine are able to destroy frozen carrion and bones. The wolverine, a larger cousin to otters, weasels and mink, has a broad head, small eyes and often has a lighter-colored face mask. The largest member of the weasel family, wolverines are fierce hunters, feeding on small rodents and even weakened caribou.
Polar bears have thick layers of fur to help keep them warm. Even though their fur is white, the skin beneath their fur is black. This came as a surprise to most people. The polar bear's black skin is completely covered by a dense under wool and long, hollow guard hairs. These guard hairs can absorb and store heat from the sun's rays. Water easily runs off the polar bear's fur because it is coated with a layer of natural oil. That means that after swimming, the bear's hair doesn't stay matted down to its body, which could easily mean a risk of freezing. Beneath their super-warm coat, polar bears have about 4 inches of blubber to help keep warm. This blubber keeps them so warm that if they don't move slowly, they can overheat. Sometimes polar bears go swimming to cool off. A polar bear's body shape differs from other bears in that its hind legs are longer than its forelegs, so its rump is higher.
It's a Wolverou!
Adaptation #5 and #6....
We'll have Cassidy guess! Let's give
her a hint. The adaptation has to do
with the feet and camouflauge of a hare.
It has the name "snowshoe" because of the large size of its hind feet and the marks its tail leaves. The animal's feet prevent it from sinking into the snow when it hops and walks. Its feet also have fur on the soles to protect it from freezing temperatures. For camouflage, its fur turns white during the winter and rusty brown during the summer. Its flanks are white year-round. The snowshoe hare is also called the varying hare because of its seasonal fur color change.
And the Final Adaptation (#7...)
An Arctic Fox Tail!
The arctic fox lives in some of the most frigid environments on the planet. Among its adaptations for cold survival is its deep, thick fur on their tail. Some ways they use their tail are they wrap their tail around their face when they are asleep to protect their face’s from the frigid arctic wind. Also, like a cat’s, this fox’s thick tail helps the arctic fox with its balance. An arctic fox tail (or brush) is especially useful as warm cover in cold weather.
