This deer is sexually ambiguous. Biologically female, it is typically able to conceive, bear and nurse fawns. But this doe typically manufactures above-average levels of testosterone, giving it a masculinity expressed through the sprouting of antlers, that crown of bone that bucks—that is, male deer—grow each year ahead of mating season....Anecdotal reports suggest that antlered does are outcasts, wary of bucks and ostracized by other does, which tend to run in small packs.
The Academy of Natural Sciences of Drexel University has over 3 million specimens in its entomology collection, but one butterfly stands out from the rest. The butterfly is literally one in a million because it exhibits both the physical characteristics of a male and a female.
