Use mimicry to startle their prey or create false target
Usually mimic poisonous or dangerous animals (harder to catch)
Some eggs use mimicry
How does camouflage work?
Camouflage used by animals to hide from predators and prey
Many animals have colourings of their surroundings but some change colour to match surroundings and texture of their surroundings
Some animals change colours for different seasons
How camouflage works (continued)
animals that change colour have skin cells of every colour that they can change size of to appear one certain colour
Some changes occur faster than others depending on the animal
Some animals two toned depending on the light from a certain angle
Why does mimicry work so well?
Many animals learn to avoid a certain plant or animal from on experience
Animals also won’t risk attacks against deadly / more dangerous animals
(hawk moth appears to be a snake when it’s a caterpillar)
Why does camouflage work so well?
Since many animals use camouflage they appear to be invisible to their predator or prey
Allowing a change of colour is even more affective for two toned areas
Mimicry: An anti-predatory device where a species copies the appearance, sound or form of a model species in order to survive.
Camouflage: A survival technique in which an otherwise visible organism may be unseen or indiscernible from its surrounding environment.
Batesian Mimicry: A type of mimicry where the mimic resembles a model species that has spines, stingers, toxic chemicals or another form of defense from predators. The mimic has none of these.
Muellerian Mimicry: A type of mimicry where an entire group of organisms bear similar markings or colours that distinguish them as inedible by predators. This means that every species with this appearance is unpalatable or toxic, not just one model species.
Chromatophores: Pigment containing or light reflecting cells that generate colour in certain animals. Chromatophores in camouflaging animals (like chameleons) change size and shape (by the muscles surrounding it) creating different colours in the animals skin.
