This July 13 photo shows a short-tailed weasel. Short-tailed weasels or ermines wear brown summer coats but white coats in winter. The animals are among the dozens of species that make up the family Mustelidae. The long, slender body form of weasels is well-suited for these predators to pursue voles and mice into narrow tunnels and tight spaces. (Courtesy Photo / Kerry Howard)

This photo available under the Creative Commons license shows a gynandromorph of a common blue butterfly. Gynandromorphy, meaning female-male-morphology, is well-known, apparently, among birds, including chickens and several songbirds of the eastern U.S.; these individuals have one half with male plumage and the other half with female plumage. They also occur in reptiles, amphibians and fishes (as well as a variety of insects and other invertebrates.) (Courtesy Photo / Burkhard Hinnersmann)
