varying throughout genera and species. The animals rub ex-hudations from the glands on various spots and objects to mark territory.

All lemuridae (and all prosimians) carry grooming combs, modified lower incisors and canines that form a comblike structure that the animals use for grooming themselves and others of their group. Mutual grooming is a social glue, maintaining and reinforcing bonds among the members of a group.

The ears are partially furred and not especially prominent, except in Lemur catta, where they are large and triangular, resembling the ears of housecats.

The hands and feet are more or less monkeylike. The pollex (thumb) and hallux (big toe) are set off more or less at right angles to the other digits and are opposable, ensuring firm holds on tree branches. The palms and soles are deeply ridged for a firm grip. A claw or clawlike nail, used for self-grooming, is present on the second toe of each hind foot.
