Abstract excerpt
Most primates have short-wavelength sensitive (S) cones and one or more types of cone maximally sensitive in the middle to long wavelengths (M/L cones). These multiple cone types provide the basis for colour vision. Earlier experiments established that two species of noctural primate, the owl monkey (Aotus trivirgatus) and the bushbaby (Otolemur crassicaudatus), lack a viable population of S cones. Because the...
