why do polar bears have black noses
some canines and bears do have diminished noses, so there would desire to be a rationalization why the polar undergo has a black nostril. this is not any. some canines and bears do have diminished noses, so there would desire to be a rationalization why the polar undergo has a black nostril. this is not any longer because of the fact there is not any fur - it somewhat is that coloration for a reason. I assume it somewhat is black instead of diminished to soak up warmth - perhaps the experience of scent is extra efficient at greater temperatures. this may be fairly damaging to the camouflage of the undergo, yet in nature there are various compromises.
Because they stick out like a sore nose on the Ice pack The skin of the polar bear is black, something that is not easy to see.
Its white fur actually all ows light to reach this skin and the dark skin absorbs the heat from the sun, another adaptation of the polar bear to living in the extreme cold of the Arctic.
The white fur of the polar bear is camouflage against the ice allowing them to blend into their environment and sneak up on their prey. This fur provides excellent insulation from the cold, even when they are swimming in the Arctic Ocean. The outer guard hairs form a layer that protects the inner fur from getting wet when the polar bear is in the ocean.
These guard hairs are hollow and filled with air. Thus, they always have a layer of trapped air surrounding their bodies. After a swim they need only give a quick shake and they are nearly dry. There is also a thick layer of blubber that helps insulate the polar bear from the cold. Their whole body is white but their noses are black. So they camouflage their noses to prevent hunters from noticing them and hunting them down.
