superfamily Lorisoidea contains two families: Lorisidae and Galagidae.
These two families have radiations that extend beyond Madagascar into
mainland Africa and Asia. Both families are nocturnal and arboreal.
Their locomotor habits are strikingly different: Lorisidae relies
primarily on slow quadrupedalism and climbing; whereas Galagidae are
known for their leaping abilities. Unlike many other prosimians, the
blood supply to their brain is supplied through the ascending pharyngeal
artery rather than through the stapedial. In the auditory region, they
also differ in having a tympanic ring fused to the bulla rather than
being suspended.</p>
