Accepted Answer

Reindeer have eyes that change colour seasonally: golden in summer (selective light transmission), blue in winter (UV amplification). The only known mammals with this adaptation — to function in endless polar twilight.

Rendieren hebben ogen die seizoensgewijs van kleur veranderen: gouden in zomer (selectief licht-doorlaten), blauw in winter (UV-versterking). De enige zoogdieren bekend met deze aanpassing — om in eindeloze polaire schemering te functioneren.
