Carefully sequestered on a perch not far above the rainforest floor, a Moyer’s Pygmy Chameleon (Rhampholeon moyeri) sleeps by night safely hidden from prowling nocturnal predators. Measuring less than 6 cm in total length, these are some of the smallest and most camouflaged in Africa – by day when they hunt for insects on the ground they are nearly invisible among the leaf litter. Recent research has shown that there is a surprising amount of diversity among Rhampholeon chameleons (26 currently recognized species), many of which are restricted to their own isolated mountain ranges. .
