aposematismo 20
Biological term introduced in the late nineteenth century, derived from the Greek apo, far away, out, and sema semates, signal, warning: warning sign: "do not attack me and things will go well for everyone". Phenomenon that occurs in the animal world and less frequently in the vegetable with colors, smells or striking sounds of warning to predators that already observed the naturalist Alfred Russel Walace. In chromatic aposematism the warning colors are usually black, red and yellow as it happens in the monarch butterflies or in the common oil mill that abounds in my land.
