  3. Introduction When you think of a polar bear, you probably think of a brown or black bear stomping their feet loudly on the forest floor. Have you ever heard of a Ursus Maritimus? I bet you haven’t. An Ursus Maritimus is the scientific name for a polar bear. Polar bears are bears that have a lot in common with brown and black bears. One of their similarities is that they both are carnivores. This is a polar bear staring off into the day. 1

  4. Body Mouth Polar Bears mouths are lined with 42 sharp teeth that can shred things like their prey easily . Also with their 42 sharp teeth is a black tongue. Their black tougue makes them unique. For example, if you were to look at a black or brown bears tougue it wouldn’t be black it would be pink like humans. When you put the black tougue and the 42 sharp teeth together, it turns out to be really dangerous . This polar bear looks cute and cuddly But when it’s teeth show it is a nasty sight. 2

  5. Blubber Polar bears (ursus Maritimu)has 4 inches of thick fat blubber. That helps the polar bear keep warm during the cold winter days. Blubber is a very important part of a polar bears body. If they didn’t have blubber they would probably freeze! Almost all polar and arctic animals have blubber. They all need blubber to survive. Blubber - This is a diagram of a polar bears fur. The yellowish part is the blubber. 3

  6. Black skin Black skin? Who has ever heard of black skin? Well, under all polar bears fur and fat is a dark , dark layer of black skin. It’s black skin helps it absorb and store heat. If a polar bear didn’t have black skin, they probably wouldn’t be as warm. These are 2 polar bears together. 4
