The facial region is reduced. The orbits are directed more to the sides than in lorids. Their postorbital processes and zygomatic arches are slender, and the bullae are considerably inflated. As in the case of most other strepsirhines, galagos have a toothcomb made up of lower incisors and canines . Their molars are similar to those of lorids.
Male galagos have a baculum, a structure that male lorids lack.
Galago species vary in food habits from being highly insectivorous to eating leaves, fruit, or gums secreted by trees. As far as is known, bushbabies live in small groups of 7 to 9 individuals, but only a few species have been studied. Scent, vocalizations, and facial expressions all play a role in social communication. L. C. Drickamer, S. H. Vessey, and J. F. Merritt. Adaptation, Diversity, and Ecology.
