Many species use their dull colours as camoflage to hide from predators. Others can spray a foul smelling and tasting liquid to stop predators from eating it.
Perhaps you're looking for the word camouflage.
Camouflage is the most appropriate answer.
Because of cryptic coloration, a form of camouflage. It is a defense mechanism used by Walking Sticks, or phasmatodea, to protect themselves against predators by blending in with their surroundings.
Yes they do. Stick Insects tend to be more active at night because there are less predators around.
Their predators include mostly spiders but if they live in an area that is well populated by assassin bugs, those too can take down a walking insect. Though some consider prey mantises as walking insects also, they are natural predators also. But mostly birds.
The number of stick insects is very low when comparing with other insects, such as grasshoppers, which live in similar habitat. Though it seems that nothing stop the grow of the population of stick insects, walking sticks are rare. Being rare is another survival factors of stick insects. The predators cannot depend on stick insects as a constant food source and have less chance to learn how to recognize the stick insects. Being rare could be considered a way of camouflage.
Both walking sticks and beetles are both insects and arthropods, as all insects are arthropods.
the Mexican walking fish defends itself against predators by camouflaging itself in the surroundings.
The same as all horses predators.
Neither. Walking sticks are insects.
I am not sure what you mean. Insects adapt to their environment in a variety of ways. Some adapt by their coloration-- for example, certain insects, like the walking stick, are brownish in color so they can blend in with trees and not be seen by predators. Other insects like ladybugs adapt by how they taste; because ladybugs are bitter-tasting, predators that see them often do not want to eat them. Other insects adapt to their environment with the ability to trap prey despite being small in size (like spiders trapping prey with a slender and very sticky web).
There is a fly that looks like a bee so that it fools predators to stay away.
Guff
Certainly. Birds.
