When the animal's patterns generally match their environment
(ex: American bittern - cattail marshes, fawns, grouse - forest floor) - ✔✔Background
matching
A type of mimicry in which a harmless species (mimic) looks like a species that is poisonous
or otherwise harmful to predators (model).
# models > # mimics - ✔✔Batesian mimicry
strongly contrasting markings such as spots or stripes break up an animal's outline -
✔✔Disruptive patterns
When disruptive patterns are aligned by body posture
(ex: American bittern or butterflies mimicking milk snake) - ✔✔Coincident disruptive
patterns
When the animal is lighter on one side of its body than the other
(ex: whirligigs) - ✔✔Bicolouration
protective coloration of some animals in which parts normally in shadow are light and those
exposed to the sky are dark. - ✔✔Countershading
Matching the environment with shape and colour
(ex: angle winged butterfly) - ✔✔Masquerade
bold and often colourful patterns that are exposed suddenly to startle a predator;
sometimes serve a deflection or distraction role
(ex: underwing moth) - ✔✔Startle patterns
, Patterns that mimic eyes used on some startle patterns. Make an animal appear 'larger than
life'
(ex: sphinx moth) - ✔✔Eyespots
Structures exposed suddenly to startle a predator
(ex: 'snake tongue' osmetarium of giant swallowtail caterpillar, wingtails, bright tongue of
five-lined skink) - ✔✔Startle structures
turtle shell - ✔✔Carapace (top) & plastron (bottom)
warning coloration - ✔✔aposematic coloration
Animals getting poison from plants - ✔✔Sequestering
Group of defended, unrelated animals that look similar - ✔✔Mullerian mimicry
Increasing in size to intimidate
(ex: toads, hognose snake) - ✔✔Bluffing
playing dead - ✔✔Thanatosis
Small birds attacking larger birds - ✔✔Mobbing
advertise awareness - ✔✔Flags
being alert and scanning the environment - ✔✔Vigilance
Larger ears capture more sound, ears pivot to scan all directions, membranes to pick up
vibrations - ✔✔Auditory vigilance
