3.10 Polar Bear Adaptations Quiz

**Passage:** Polar bears are amazing animals that live in the cold Arctic. They have special adaptations that help them survive in their icy home. One important adaptation is their thick fur. Polar bears have two layers of fur: a soft undercoat and longer guard hairs. This keeps them warm, even when the temperature is far below freezing. Their fur also looks white, which helps them blend in with the snow and ice, making it easier to sneak up on seals, their main prey. Another adaptation is their strong claws. Polar bears have large, sharp claws that help them catch and hold onto slippery seals. These claws also help them walk on ice by gripping the surface, so they don’t slip. Their claws are curved and powerful, perfect for digging through snow or breaking into seal dens. Polar bears also have strong teeth. Their sharp canine teeth help them bite through the thick skin and blubber of seals. Their back teeth are flat and wide, which helps them chew their food. All these adaptations—thick fur, strong claws, and sharp teeth—work together to help polar bears survive and thrive in the harsh Arctic environment. **Question:** What is one way polar bear fur helps them survive in the Arctic?

• It helps them swim faster.

• It keeps them warm in cold temperatures.

• It makes them look bigger.

• It helps them see better.
