Cripsis, mimicry and aposematic
The crypsis or camouflage is a phenomenon whereby an animal has adapted to go unnoticed. That is, it camouflages with the environment, because it uses similar colors to the surrounding natural elements, patterns of colors that hide its outline, to stand still, etc.
mimicry, however, is the ability of certain animals have to look to others around. The purpose of mimicry may be the crypsis, pass unnoticed by predators and the survival.
The opposite is aposematic: Some organizations have very striking features to understand that predators are dangerous. For example, the coral snake has red, black and yellow showy. Another example is the bees or wasps, with their colors warn that dangerous.
The aposematic is used by other animals, there is a type of camouflage called Batesian mimicry, where harmless species taken the appearance of another dangerous, thus gaining an advantage defensively, as the false coral, or flies that look like bees or wasps.
For example, this kind Syrphidae fly or flower fly, is much like a bee. animal camouflage photos:
