grooming

views updated

grooming Behaviour that is concerned with the care of the body surface, performed by an animal upon itself (auto-grooming), or by one animal upon another of the same species (allogrooming). In some animals (e.g. rodents) the spreading of saliva on the fur during grooming may serve a role in thermoregulation. Autogrooming may serve to change the state of arousal of an animal; allogrooming strengthens social bonds and helps to provide all members of a group with a scent characteristic of the group, by means of which group members may identify one another.
