对W的视觉敏感性的发现可以追溯到1882年，是在昆虫蚂蚁身上发现的，但在过去的15年里，在许多脊椎动物中发现了对紫外线最敏感的光感受器的证据。对拥有一种以上光谱感光器的昆虫的行为反应的研究产生了波长相关行为的概念。这些现象与色觉不同，在色觉中，颜色信息可以用于多个联想。最近对脊椎动物的研究表明，各种行为反应似乎是基于受体光谱类别的特定组合。其中包括对紫外线最敏感的鸟类的行为反应，这是一个令人惊讶的发现，因为鸟类的视网膜只包含相对较少的锥体，在紫外线中具有最高的敏感性。这些例子和其他例子，都暗示了节肢动物的波长依赖行为和行为学的“释放者”行为，再次强调了需要超越灵长类颜色视觉的范例的解释性概念，以及更多地关注非哺乳动物脊椎动物视觉定向行为的个体发育。迅速积累的关于视蛋白进化关系的数据继续表明，在特定的视蛋白谱系中，基于视网膜的视觉色素的吸收最大值彼此之间大约在40 nm以内。某些紫外线颜料可能是这一概括的第一个例外。
The discovery of visual sensitivity to W dates from 1882 and was made in an insect, the ant, but in the last 15 years evidence for photoreceptors maximally sensitive in the UV has been found for many vertebrates. Studies of behavioral responses of insects that possess more than one spectral class of photoreceptor have generated the concept of wavelength-dependent behaviors. These phenomena are distinct from color vision, where chromatic information can be used in multiple associations. Recent work on vertebrates has shown a variety of behavioral responses that appear to be based on specific combinations of spectral classes of receptors. Among these are behavioral responses of birds that are maximally sensitive in the UV, surprising findings since the retinas of birds contain only relatively small numbers of cones with peak sensitivity in the UV. These and other examples, suggestive of both wavelength-dependent behaviors of arthropods and ''releasers'' of ethology, emphasize anew the need for explanatory concepts that reach beyond the paradigms of primate color vision and for greater attention to the ontogeny of visually-directed behavior in non-mammalian vertebrates.The rapidly accumulating data on the evolutionary relationships of opsins continue to suggest that within specific opsin lineages the absorption maxima of the retinal-based visual pigments lie within about 40 nm of each other. Some UV pigments may provide the first exception to this generalization.
