Animals might not be able to speak but they certainly have other ways of communicating. Whale song, wolf howls, frog croaks, bird chips even the waggle dance of the honeybee or the vigorous waving of a dog's tail are among the panoply of ways animals transmit information to each other and to other denizens of the animal kingdom. Species often rely on verbal and nonverbal forms of communication, such as calls non-vocal auditory outbursts, like the slap of a dolphin's tail on the water bioluminescence scent marking chemical or tactile cues visual signals and postural gestures. Fireflies and peacocks are classic examples of brilliant bioluminescence. Ants use chemical cues to help guide their foraging adventures, as well as for other activities like telling friend from foe, connecting with new mates and marshalling the colony's defenses.
