MIMICRY • One organism imitates another; resembles another organism in some way • Do you see a difference in these 2 butterflies? The butterfly at the top is a MONARCH; eats milkweed which gives it a bad taste so birds don’t eat them; The bottom butterfly is a VICEROY; birds leave alone b/c it looks like monarch

MIMICRY • What about these 2 snakes? The top snake is a coral snake, which is very poisonous. The bottom snake is a milksnake…harmless

BENEFITS • Because the harmless organism looks like a poisonous or bad tasting organism…predators

BENEFITS • Because the harmless organism looks like a poisonous or bad tasting organism…predators leave them alone! support FOR EVOLUTION Shows the organism has changed in order to “mimic” another organism or feature

 • Organisms have features that allow them to blend in with their environment

• Organisms have features that allow them to blend in with their environment • Therefore avoid contact with predators (BENEFIT!) • Do you see the organisms in these pictures? • In what way are these organisms camouflaged? • Supports evolution b/c organisms changed to blend in with environment CAMOUFLAGE
