Animals communicate in numerous ways. Usually, when animals communicate, the receiver of the communication responds by changing its behaviour. Communication can use any one or more of the senses including vision, hearing, smell and taste, touch, and electric senses. ‘Signals for survival’ explains that across the animal kingdom, signals within a species are generally honest. Cheating is pointless when the benefits from a signal are mutual, but broadcast signals can be eavesdropped by other species. Communication is risky when a signal appears to be from a potential mate, but is instead being made by a deceptive predator. Interspecies communication is also discussed, along with details of honeybee dances and vervet monkey alarm calls.
