The specialization of the owl monkey retina for night vision

The anatomy of the owl monkey (Aotus) retina is reviewed and compared with that of one of its diurnal relatives, the capuchin monkey (Cebus). A mechanism is suggested by which the owl monkey has biased its retinal organization towards a conformation most advantageous for scotopic vision. © 2000 John Wiley & Sons, Inc.
