The saiga antelope’s nose is undoubtedly its most distinctive feature. This bizarre, bulbous appendage is an adaptation that enables the saiga to survive the tough conditions and extreme seasonal temperature swings in its native habitat. The swollen nostrils filter out dust and cool the blood during hot, dry summers, and act as a radiator in winter to warm the cold air before it enters the saiga’s lungs. Other seasonal adaptations include a thick winter coat that the saiga sheds when the weather warms up.
