Were you aware that male polar bears are twice the size of their female counterparts?
While it may seem like these magnificent creatures are simply white, furry, and inhabit cold regions, there is so much more to learn about them.
In fact, polar bears are incredibly complex and have evolved over time to adapt to their environment.

International Polar Bear Day is celebrated on February 27th each year.
The Latin name for polar bear is “ursus maritimus”, which means “maritime bear” in English.
Polar bears can be found in North America and Eurasia, primarily around the Arctic Circle. Although some have been spotted traveling as far south as Alaska and Canada’s Hudson Bay.
During the winter months, polar bears usually reside on the ice or near it, although they have been known to migrate up to 124 miles (199 kilometers) inland from the shore.
As the ice melts, these bears will migrate within their “home range”, which ranges from 50,000 to 135,000 square miles (129,499 to 349,648 square kilometers).
Polar bears can travel more than 1,800 miles (2,896 kilometers) in a year to follow their food supply.
These bears can jump over ice cracks as wide as 19 feet (5.8 meters) while traveling across the ice.
Polar bears are the only bear species classified as marine mammals, as they spend the majority of their time on sea ice.
Although their fur is white, their skin is actually black. The fur reflects light, making them appear white.
Their paws have small hairs on the bottom to provide traction on the ice, rather than simply keeping them warm.
While swimming, polar bears can reach speeds of up to 6 mph (9.6 kph).
Polar bears can swim continuously for hours, and sometimes even days, due to their large paws, which function as paddles, and their feet, which act as rudders.
Despite spending half their time hunting for food, polar bears are rarely successful, with less than a 2% success rate.
Seals and bearded seals are their primary prey, but they will also scavenge carcasses, eggs, and vegetation.
As “hypercarnivores”, polar bears have diets consisting of over 70% meat.
The Grolar Bear or Pizzly Bear, a Grizzly Bear-Polar Bear hybrid, was discovered in 2006 through genetic testing.
These bears are only birthed by polar bears and have brown fur, but they grow up living like polar bears.
The population of wild polar bears is divided into 19 sub populations, with only one on the rise, five stable, and four in decline while nine remain uncertain. Male polar bears can weigh up to 1,764 lb (800 kg) and grow to be 9.8 feet (3 meters) long, making them the largest land carnivores in the world. Female polar bears are around half the size of males. Polar bears have an incredible sense of smell, enabling them to detect prey up to 0.6 miles (1 kilometer) away and locate seal breathing holes in the ice. They track down seals and wait by their holes, attacking when they rise for air. Despite having a still hunting technique, they can also attack prey from 50-100 feet (15-30 meters) away and reach speeds of 25 mph (40 kph). Polar bears are threatened by climate change and are expected to decline by 30% by 2050. It has been discovered that polar bear DNA can be retrieved from their footprints in the snow. Other than pregnant polar bears, they are the only bear species that do not hibernate during winter. The largest polar bear ever recorded weighed 2,209 lb (1,002 kg) and was found in northwestern Alaska in 1960. While polar bears have adapted to survive in their habitat, global warming and climate change are negatively affecting them, potentially leading to extinction. However, conservation projects are helping some polar bear populations increase, and efforts to reduce the effects of global warming can aid in saving polar bears.
FAQ
1. What is the scientific name for polar bears and where can they be found?
The scientific name for polar bears is Ursus maritimus, which means “maritime bear.” Polar bears can be found in the Arctic regions of Alaska, Canada, Greenland, Norway, and Russia.
2. What is the average size of a polar bear?
The average size of a male polar bear is about 8-10 feet long and can weigh up to 1,500 pounds. The average size of a female polar bear is about 6-8 feet long and can weigh up to 550 pounds.
3. How do polar bears stay warm in the cold Arctic environment?
Polar bears have a thick layer of insulating fat, which can be up to 4.5 inches thick. They also have a dense fur coat that helps to keep them warm. They also have the ability to regulate their body temperature by changing the rate of their metabolism.
4. What do polar bears eat and how do they catch their prey?
Polar bears mainly eat seals, but they will also eat fish and other marine animals. They catch their prey by waiting at the edge of the ice, where the seals come up to breathe. When the seal comes up for air, the polar bear will grab it with its powerful jaws.
5. How long can polar bears go without food?
Polar bears can go without food for several months, especially during the summer months when the ice melts and their hunting grounds disappear. During this time, they will rely on their fat reserves to survive.
6. Are polar bears endangered?
Yes, polar bears are listed as a threatened species. The main threat to their survival is the loss of sea ice due to climate change. Without sea ice, polar bears are unable to hunt for their food and their populations are declining. Conservation efforts are underway to protect polar bears and their habitats.
