have you ever seen dancing bees, gorillas sticking their tongues out? well, you may be surprised to learn that these are not just the things they do to entertain themselves or visitors at the zoo!
smell. the sense of smell is the easiest way to communicate even the simplest creatures. many animals, including humans, release odors to attract other people to breed, save predators or attract prey, and so on.
sight. many animals make extensive use of body language to convey their thoughts. the female rabbit, for example, shows the white lower part of the tail to tell young ones to follow her to the mink.
sensory. not only do people shake hands when they meet - chimpanzees also greet each other.
sound. we all woke up with the pleasant sound of birdsong, but birds are not the only animals that use the sense of sound to communicate. for example, the world's largest mammal, the whale, has a complex repertoire of songs. virtually all animals say something.
