Nature is full of amazing wonders. Every living thing has special skills to survive in its environment.
Chameleons are famous for changing their skin color. They do this to hide from enemies and communicate with other chameleons. Their color can change depending on the temperature, light and even their mood.
Mimosa pudica, also called the sensitive plant, closes its leaves when touched. This is a way to protect itself from being eaten by animals. After a few minutes, the leaves will open again slowly.
Bats use echolocation to find food and avoid obstacles. They send out high-frequency sounds that bounce off objects. By listening to the echoes, bats can know exactly where things are, even in complete darkness.
Bees dance to tell other bees where to find food. A special “waggle dance” tells the direction and distance of flowers with nectar. This helps the whole hive work together efficiently.
