Blind Golden Moles Have a Blue-Green Iridescent Sheen, a Rare Example in Mammals


Golden moles, mammals forming the family of Chrysochloridae, which taxonomically is distinct from true moles but to which they resemble due to species convergence, are a small, insectivorous family of burrowing mammals native to southern Africa. It was recently discovered that they have a blue green sheen to their coats, which is a rare example of iridescence in mammals.
