Polar bears have dark brown eyes.Their eyes are quite close together and face forwards.
'External features' means the outside parts of the thing so, for the polar bear, it will be nose, skin, legs, hands, eyes, and lips.
The visual answer is that the face is white, and the only black on a polar bear's face is its eyes, nose and mouth. The more technical answer is that a polar bears fur in all actually transparent. Their skin underneath is black. See the related link for a polar bear face picture.
The grizzly or brown bear and the polar bear are basicly the same size.
why does the polar bear helps the polar ice
The Polar Bear has eyes with an additional inner eyelid, or second eyelid. This makes it possible for the Polar Bear to be exposed to the glare of the sun on the ice and snow, without blinding them. They also keep their eyes open under water, and can see very well under water. For more details, please see sites listed below.
On moonless nights, the bear relies on its eyes to see at night. Optical receptors called rods and cones are needed to distinguish light and dark and colour, respectively. At night an animal, like a polar bear, must have more rods than cones when seeing things at night in its eyes.
