What is short-faced bear vs polar bear?

Short-faced bear (Arctodus simus):

• The short-faced bear, also known as the bulldog bear or the giant short-faced bear, is an extinct species of bear that lived in North America during the Pleistocene epoch, around 2.5 million to 11,000 years ago.
• It is called the short-faced bear because of its relatively short snout compared to other bears.
• Short-faced bears were the largest mammalian carnivores to have ever lived on land, with an estimated weight of up to 900 kg and a height of up to 3.4 meters.
• They were known for their incredible speed and agility, and were able to run at speeds of up to 56 km/h, making them one of the fastest bears, as well as one of the fastest land animals of their time.
• They were likely apex predators, feeding on large mammals such as bison, horses, and mammoths, as well as scavenging on carrion.

Polar bear (Ursus maritimus):

• The polar bear is a species of bear that is found primarily in the Arctic region of the Northern Hemisphere, including Canada, Greenland, Norway, Russia, and the United States (Alaska).
• It is known for its white fur, which provides excellent camouflage in its snowy habitat, as well as its large size, with males weighing up to 800 kg and standing up to 3 meters tall on their hind legs.
• Polar bears are excellent swimmers, able to swim for long distances and dive to depths of up to 4.5 meters to catch prey such as fish, seals, and other marine mammals.
• They are also opportunistic eaters, and will feed on carrion, as well as raiding bird nests and scavenging on human garbage.
• Polar bears are threatened by climate change, which is causing the melting of sea ice and reducing their hunting grounds and food sources.
