Signal Production, Vocalization, Chemical Signals

Animals communicate by sending and receiving signals. For example, a mother dingo (Canis lupus dingo) can communicate certain types of information to her pups by using tactile signals conveyed through grooming.

Cactus wrens (Campylorhynchus brunneicapillus) sing to communicate with other members of their species.

Wolves are social animals, and they thus require a large repertoire of signals to communicate different kinds of information.

Blue arrow-poison frogs (Dendrobates azureus) can communicate through sound production. Their bright colour also serves as a warning signal to predators.

Katydids use several different forms of communication. One of these forms is called stridulation and is characterized by the rubbing together of the insect's wings to create sound waves. These sound waves convey specific types of information and are detected by members of the same species.

Bats have special resonating structures attached to their sound-producing organs that select specific sound frequencies. This enables them to use different sound signals in different contexts.

Fireflies such as those of the genus Photinus produce their own light as a means of communication.
