The sifakas are relatively large lemurs that are diurnal, or active during the day. These lemurs are called sifakas because of the sound of their distinct “si-fak!” call. They have extremely long legs and their favorite position to “hang out” in is vertical, clinging to tree trunks. Those same long legs help them leap powerfully from tree to tree, sometimes resembling a basketball player at the apex of a rim-rattling slam-dunk. But on the ground sifakas are equally captivating, bounding along in a comical sideways dance with arms flailing overhead for balance.
