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.
蛇类基因组仅编码两种视蛋白用于视网膜中的视锥细胞，这限制了它们的适应灵活性和色觉。研究表明，通过使用替代视蛋白等位基因，一些海蛇可能会在其视网膜中增加第三种视蛋白光谱类型。
