"Chameleon" PPT

Part One: Protective Colors of Animals

In nature, there are many animals, such as chameleons, who in the process of adapting to the environment, make the color of their bodies the same or similar to the color of the surrounding environment, all in order to hide themselves or escape from enemies.

We call this method of animals protecting themselves: protective coloring

Independent exploration, cooperation and communication:

Based on the colors and shapes of these animals, please tell us which animals use the same method as the leaf-backed mantis and dead-leaf mantis to protect themselves?

Like the dead leaf butterfly (leaf insect), not only the color is similar to the surrounding environment, but also the shape is close to the dead leaves (leaves). They protect themselves from other predators by resembling the color and appearance of dead leaves (leaves), which is one organism's imitation of the form of another.

We call this method of protecting ourselves mimicry

Poison dart frogs, like poison dart frogs, use bright colors to warn predators not to eat them. This way animals protect themselves is called warning coloration.
