Senses

A. Hearing.
A polar bear's hearing is probably as sensitive as human hearing. Humans can hear sounds with frequencies as low as 0.02 kHz and as high as 20 kHz.

B. Eyesight.
The eyesight of polar bears appears to be similar to human's. Polar bears have a protective membrane over their eyes, that may help shield the eyes from ultraviolet light.

C. Tactile.
Little is known about a polar bear's sense of touch; however, polar bears have been observed delicately moving or touching objects with the nose, tongue, and claws.

D. Taste.
Polar bears prefer certain foods, but researchers don't know how acute the sense of taste is or how important it is in food preference.

E. Smell.
A polar bear's sense of smell is acute, and it is the most important sense for detecting prey on land. A polar bear can smell a seal more than 32 km (20 mi.) away .
