Sensory Ecology: In Sea Snake Vision, One Plus One Makes Three

Snake genomes encode only two opsins for use in retinal cones, limiting their adaptive flexibility and color vision. Research now shows that, by using alternative opsin alleles, some sea snakes may add a third opsin spectral class to their retinas. Snake genomes encode only two opsins for use in ret...
