Summary
Colour and form evolve to hide or imitate other species, as in Batesian and Mullerian mimicry.
In depth
Crypsis blends with background; Batesian mimicry is harmless species resembling dangerous (hoverflies and wasps); Müllerian is shared warning signals among harmful species. Aposematic colours warn predators.
Colour change in cuttlefish uses chromatophores. Disruptive colouration breaks outlines. Warning colours advertise toxicity.
Key idea: predators exert strong selection on prey appearance.
Crypsis includes background matching (peppered moth), disruptive coloration, countershading (dark on top, light below), and masquerade (stick insects, leaf insects resembling objects). Cephalopods and chameleons change their appearance. Aposematism is warning colours in toxic animals (poison dart frogs, monarch butterflies, which sequester milkweed toxins).
Batesian mimicry has a harmless species copying a harmful model, and works only when the model is common enough; Müllerian mimicry has several harmful species sharing a pattern, as in Heliconius butterflies, where the shared signal speeds predator learning. Aggressive mimicry involves a predator disguised as harmless, such as anglerfish lures or Photuris fireflies.
Example: hoverflies with wasp stripes are Batesian mimics, lacking a sting.
