一只雌性斑海豹被训练来区分蓝色和橙子的发光目标。亮度线索从颜色线索和背景光强度是这样的，动物的杆可能饱和。动物的表现表明，它可以可靠地区分颜色。这提供了第一个证据，表明海洋哺乳动物的眼睛中有一种以上的视锥类型。
A female spotted seal was trained to discriminate between blue and orange lighted targets. Brightness cues were decoupled from color cues and background light intensity was such that the animal's rods were probably saturated. The performance of the animal indicated that it could reliably distinguish colors. This provides the first evidence implying more than one cone type in the eye of a marine mammal.
