As Fig. 11a makes clear, MSP is of little use in defining cone spectral sensitivities except close to the photopigment λmax. The large discrepancies between MSP and other estimates of cone spectral sensitivities arise because of the small signal to noise ratio of the MSP

Extant vertebrates typically have four cone opsin classes (LWS, SWS1, SWS2, and Rh2) as well as one rod opsin class (rhodopsin, Rh1), all of which were inherited from early vertebrate ancestors. These five classes of vertebrate visual opsins emerged through a series of

Animals living on land and marine fish form their visual pigments exclusively with retinal 1. However, many freshwater fish and amphibians can also form visual pigments with retinal 2, depending on the activation of the enzyme

While opsins can only bind retinal, there are two forms of retinal that can act as the chromophore for vertebrate visual opsins:

There are two classes of vertebrate visual opsin, differentiated by whether they are expressed in rod or cone photoreceptors.
