Animals, plants, birds, and insects display many different colors; blue, red, yellow, green, and more. Some living creatures are patterned, while others are multicolored. Their colors serve to ensure the survival of their species.
There are many reasons why animals appear in various colors. One reason is that an animal’s coloring can help it to blend in. Animals that use this defense strategy include zebras, lions, and insects. This helps them to escape from predators and harm or even to hunt their prey.
Some animals can also change their appearance to match the environment they are in, called camouflage. Camouflaging is a way of disguising or mimicking. Species that do this include chameleons, octopuses, weasels, fish, eagles, and even Brazilian tapirs. Other examples of camouflaging insects are the stick insect and the leaf insect.
Similarly, poisonous animals usually have colors that act as a warning. They are typically red, white, green, or black. These creatures use camouflage to keep safe from other living things, like the flower mantis and the bee orchid plants.
Animals and even plants use color to express warnings, to communicate, or even to escape from predators. Imagine how different the animal kingdom would be if the world were black and white!
