Spectral sensitivity of photoreceptors in an Australian marsupial, the tammar wallaby (Macropus eugenii)

Hemmi, Jan; Maddess, Ted; Mark, R F


Microspectrophotometric measurements on the rod photoreceptors of the tammar wallaby showed that they have a peak absorbance at 501 nm. This indicates that macropod marsupials have a typical mammalian rhodopsin. An electroretinogram-based study of the photoreceptors confirmed this measurement and provided clear evidence for a single middle wavelength-sensitive cone pigment with a peak sensitivity at 539 nm. The electroretinogram did not reveal the presence of a short-wavelength-sensitive cone...[Show more]
