- Thick fur: Polar bears have a thick, white coat that helps them stay warm in the cold Arctic waters. The fur is made up of two layers: a dense undercoat that traps heat and a longer, outer coat that sheds water and snow.
- Large paws: Polar bears have large, webbed paws that help them distribute their weight on ice and snow. The paws also help them swim and hunt in the water.
- Long neck: Polar bears have long necks that allow them to reach into the water to catch prey. The long neck also helps them scan the horizon for prey and predators.
- Strong sense of smell: Polar bears have a strong sense of smell that helps them track prey and find food. They can detect the scent of seals from several miles away.
- Keen eyesight: Polar bears have keen eyesight that helps them spot prey in the snow and water. They can also see objects in low-light conditions, which is helpful for hunting at night.
- Sharp claws: Polar bears have sharp claws that help them grip ice and snow. The claws also help them catch and kill prey.
- Ability to store fat: Polar bears can store large amounts of fat in their bodies, which helps them survive through periods of fasting when food is scarce.
- Ability to withstand extreme cold: Polar bears can withstand extremely cold temperatures, thanks to their thick fur, large paws, and ability to store fat. They have been known to survive in temperatures as low as -50 degrees Fahrenheit.
