![]() ![]() Nocturnal activity is more prevalent during nights when the moon is brightest. It is hypothesized that since lemurs’ eyes lack a tapetum lucidum, which is the structure in the eye that enhances night vision, they may have a difficult time seeing when the moon is less bright. The highest activity rates occur between 6 and 8 a.m. ![]() They are cathemeral primates, that is, they are active at any time of the day or night depending on the circumstances, such as food availability, predatory threats, and ambient temperatures. Both distance and speed of travel are reduced during the dry seasons, when resources are much more scarce.īlack lemurs are, interesting, neither solely diurnal (active during daylight hours) nor nocturnal (active at night). When they descend to the ground (typically for food), they travel on all fours with bouts of bipedal leaping.
