Why do some animals have a bright, unmasking color, while others, on the contrary, are protective?

Two types of coloring correspond to two variants of a behavior strategy. With one of them, the animal seeks to go unnoticed, trying to avoid meeting a predator or sneaking up on a prey. For this, a protective coloring is used, which allows merging with the background. On the other hand, animals that are dangerous or poisonous often emphasize this in every way. They use a bright unmasking color, warning: “Do not eat me.” In addition to poisonous organisms, this strategy is used to mimic harmless species under them. Organisms can have a unmasking color and for a completely different reason – in connection with the desire to attract a partner for reproduction (bright color of many male birds, fish, reptiles, butterflies, etc.). In this case, the task of procreation conflicts with the instinct of self-preservation, but it turns out to be more significant for the body.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
