Not all animals use camouflage because there are situations where it is good to show themselves off. One case is the need to find and keep a mate. Many male animals have some bright colours during the mating season, or change their behaviour and come out into the open. Without this, they might not succeed in mating. Their females, on the other hand, are usually dowdy and camouflaged. This pattern occurs in almost all animals where the male displays and the female chooses. There is at least one good reason the female stays camouflaged. The moment she is fertilized she carries the precious cargo: the eggs that will form part of the next generation.
