Themed notes: Animal communication KS4 and 5 Animal communication Animals communicate in a variety of ways to pass on information to each other. Messages can be about all sorts of things e.g. territory, food, attracting a mate. Messages can be intra-specific (to members of the same species) or inter-specific (to members of another species). Animals that live in social groups tend to have more complex communication than solitary species as groups have to cooperate in order to survive. Chemical communication Background • Chemical communication is based on taste and smell. • Pheromones are a type of chemical which causes a behavioural change or developmental reaction in another member of the same species. • Chemical signals can be used for a variety of reasons such as attracting a mate, marking territory or as a warning. • Chemical signals are particularly useful because they can persist in the environment for long periods; useful for species that have large home ranges and use chemicals to mark their territory. Things to do and think about: • Visit the hippo house and consider the following questions. • How do hippos use chemical communication? • What message do you think the hippos are trying to get across and who is it to? Other species that use chemical communication you could look out for: lions, otters, ants, rhinos and dwarf mongoose. Visual communication Background • Visual communication is advantageous as it is one of the fastest way to communicate. • Information is communicated through colour, shape, movement and posture. • Visual communication is limited in its range and can be seen by others individuals unintentionally. • The use of body language is particularly used in social species. Complex behaviours have been developed such as gestures and facial expressions. Things to do and think about: • Spend some time observing the chimps. Watch for facial expressions and body language. • Did you observe any communication between individuals? Describe what you saw without attaching feelings to the actions. (Although some chimp communication is easy to understand some gestures and facial expressions don’t mean the same as when a human does it e.g. if a chimp grins showing all its teeth it isn’t happy; that expression is known as a fear grin. Other species to look out for: • When you have the opportunity look up chimp communication wolves, meerkats, ostrich, on the internet and see if you can find out what the chimp was brown bears and peacocks trying to say. Themed notes: Animal communication KS4 and 5 Things to do and think about: • Watch the lions to see if they use tactile communication What body parts do they use? • Other than to clean each other, why do you think lions lick and groom other members of their pride? Other species to look out for: cheetah, Asian rhino, European lynx, ring-tailed lemurs. Tactile communication Background • Tactile communication is communicating using touch. • It is a very direct and instant way of communicating with another individual. However it can only be used when animals are close to each other. • Tactile communication is highly developed in social mammals and birds but many other species use it too. • It is commonly used when mating and between parent and offspring. Vibrations Background Things to do and think about: • The use of vibrations to communicate has only recently been • Find out how and why discovered. elephants communicate long • Vibrations can be transmitted distance using through materials such as spider vibrations (sound webs, soil, water and vegetation. waves we can’t hear). • Vibrations can travel long distances. Acoustic communication Background • Acoustic communication is the use of sound to communicate. • This method of communication is very versatile and can travel quickly in water and air. • An advantage of this type of communication is that it can be used over long distances however a disadvantage is that sounds can be heard by other individual unintentionally. Things to do and think about: • Watch and listen to the meerkats. Why do you think they constantly make noises when they are foraging? • What do you think they will do if they spot a predator? • Listen to each meerkat’s call. Can you tell the difference between each individual? Do you think the meerkats can?
