Final answer:
Camouflage rules include blending with the environment and avoiding detection by predators through adaptations like body shape and coloration. The tropical walking stick and the chameleon are classic examples, using these methods not just at night, but throughout the day to gain a survival advantage.
Step-by-step explanation:
The general rules of camouflage involve organisms using their body shape and coloration to blend into their environment and avoid detection by predators. Mimicry and camouflage are crucial survival adaptations that provide a significant advantage to individuals that have developed these mechanisms.
For instance, the tropical walking stick resembles a twig, making it hard to differentiate from actual twigs when it remains stationary. On the other hand, organisms like the chameleon can actively change their coloration to match their surroundings.
These strategies are not confined to the night but are effective during the day as well. Examples include using drab colors to avoid drawing attention (drawing attention to oneself), matching the hues and patterns of the environment (blending with the surroundings), avoiding vibrant colors that stand out (wearing vibrant colors), and employing camouflage during all times of the day to avoid predation (using camouflage only at night).
