background image ANS 042 Week 2 1/19/18 Lecture 5 ­ Communication Animals use visual, olfactory, tactile, audible forms of communication Communication: the transmission of information that alters the receiver’s behavior Body language can be used to determine who is who in a hierarchy Visual communication Displays: stereotypical behaviors that contain information clearly understood by a
member of its own species and other species
Refers to communication Ex: a cat that hisses and arches its back, we know that it is in fear Similar facial contortions can mean completely different things to different 
species
A human showing teeth vs. a wolf showing teeth mean completely
different things
Children look at dogs with “hard eyes” meaning they stare at them head 
on, and dogs find that uncomfortable ­ results in children getting bitten in 
the face
Displays are evolutionarily favored b/c if you can threaten with a body 
posture, it is more cost effective than wasting energy on a fight
Olfactory communication: by scent or odors Referred to as pheromones: chemicals that make up informational odors Synthesized by the body specifically for information OR they are a 
metabolic byproduct OR by organisms that live on the animal
How animals define their territory Most species can recognize members of their own species by scent All animals use this form of communication Bunt: rubbing of cheek sebaceous glands to site mark Site marking is marking territory Cats do this to mark territory; the head butt in cats is the welcoming 
behavior, not the cheek rub
Certain odors can convey the age of an animal Long lasting and can travel long distances Tactile communication Forms of tactile communication Touch Mutual grooming Hand shakes Fights Audible communication Uses of vocal communication Alert for danger
