Have you ever wondered how animals survive in the freezing Arctic? It’s a place where it’s super cold, the wind is strong, and the amount of daylight changes a lot throughout the year. Despite these tough conditions, some amazing animals have special features that help them live there all year round. Today, we’re going to learn about one of the coolest Arctic animals: the polar bear!
Polar bears are incredible creatures that are perfectly adapted to life in the icy Arctic. To stay warm in the freezing temperatures, they have two layers of fur. The first layer is a soft and thick undercoat that keeps them cozy. On top of that, they have guard hairs that are hollow and help keep water away from their warm undercoat.
Even though polar bears look white, their fur is actually transparent! The hollow spaces in their hair scatter and reflect light, making them appear white. This is a great trick for sneaking up on seals. Underneath their fur, polar bears have black skin that absorbs heat from the sun, keeping them warm.
Besides their special fur, polar bears have a thick layer of fat called blubber under their skin. This blubber acts like a warm blanket, providing extra insulation. They also have big paws with long, sharp claws that help them catch their prey. Their powerful jaws and sharp teeth make them excellent hunters, and their large paws help them swim really well.
Polar bears are the largest land carnivores, which means they eat meat. They can grow up to nine feet tall and weigh almost a ton! Their size helps them hunt big animals like seals, walruses, and even whales.
Polar bears rely on floating sea ice to travel and hunt. Sadly, because of climate change, the ice is melting quickly. This makes it harder for polar bears to find food and survive. Although they are not endangered yet, their numbers are going down.
We can all do our part to help protect the planet and these amazing polar bears. By learning more about them and taking action to reduce climate change, we can make a difference. Thanks for learning with us today!

In the Arctic environment, conditions are extremely harsh for any organism to survive. It is bitterly cold, with strong winds, and the amount of daylight changes drastically from season to season. However, some organisms have fascinating adaptations that allow them to thrive in the Arctic for all or most of the year.
Today, we will explore one of the most well-known and formidable Arctic animals: polar bears. A worksheet related to this video can be found in the link in the description; you may want to download it now and complete it as you watch.
These remarkable animals are perfectly suited to the icy Arctic. To withstand the constant freezing temperatures, polar bears have two layers of transparent fur. They possess a soft and thick undercoat that keeps them warm, along with an upper layer of guard hairs that are hollow and help to repel water from the insulating undercoat.
Polar bears appear white, which is an excellent adaptation for sneaking up on unsuspecting seals. However, their fur is actually transparent and hollow. They appear white because the hollow air spaces in each hair scatter and reflect light of all colors, meaning no color within the visible light spectrum is absorbed. Beneath the guard hairs and undercoat is a layer of black skin, which absorbs heat effectively as sunlight passes through the transparent hairs.
In addition to their fur, polar bears have a thick layer of fat called blubber beneath their skin, providing further insulation. They also have large pores and long, sharp claws that help them catch and tear flesh from their prey. Their powerful jaws and sharp teeth assist in this process, and the large surface area of their paws makes them excellent swimmers.
As top predators, polar bears are the largest of all land carnivores, reaching heights of up to nine feet and weighing close to one ton. Their enormous size allows them to prey on other large animals, including seals, walruses, and even whales.
Polar bears depend on floating sea ice to move from place to place and to catch prey. Unfortunately, human-induced climate change is causing our planet to warm, leading to the rapid melting of sea ice. Although polar bears are not currently endangered, their numbers are declining.
Let’s all take action to protect our planet and the magnificent polar bear. Thank you for learning with us today!
