Scientific name for polar bear: The polar bear is one of the most famous and beautiful predators in the world. It is perfectly suited to the harsh, frozen conditions of the Arctic. If you're interested in nature, learning about how species like the polar bear are officially classified is a great place to start. There are about 26,000 polar bears living in the circumpolar Arctic region right now.
This marine mammal, which is the biggest type of bear, has a lot of problems, mostly because of climate change, which is causing sea ice to melt. So, knowing the right scientific name for a polar bear can help us understand its place in the animal kingdom better and why it needs to be protected right away.

Interesting Facts about Polar Bears
Polar bears are amazing examples of evolution because they have special adaptations that let them live in one of the harshest places on Earth.

1. Marine Mammal Classification
Not many people know ‘Where do polar bears live?’ These bears are the only kind of bear that lives in the ocean and needs sea ice for food and shelter. They mostly eat seals.
2. Insulating Fur and Skin
Even though their fur looks white to blend in, each hair is actually clear with a hollow center. Beneath the fur, their skin is jet black, which helps absorb sunlight and warm them.
3. Exceptional Swimmers
Polar bears are great swimmers. They can swim for a long time and move through the water at speeds of up to 6 mph.
4. No True Hibernation
Unlike their black and brown bear cousins, polar bears (except for pregnant females in dens) do not undergo true hibernation in winter, as this is their crucial season for hunting seals on the ice.

The scientific name for a polar bear, Ursus maritimus, really shows how well it lives in the ocean. These beautiful carnivores, which belong to the Ursidae family and depend on ice, are a very important indicator species for the health of the Arctic ecosystem. It is important to keep working to protect this famous "sea bear" so that it can continue to roam the northern ice floes for many generations to come.
