Although many fish (and some invertebrate) species are capable of changing color dramatically, we don't often see them in the process of changing colors.
This morning, I followed a small honeycomb cowfish (7 inches long), and watched it change. This species is a member of the boxfish family, and has sharp spines above the eyes. These photos were taken at a depth of about 45 feet. Within a minute this fish went from very little blue pigment to quite a lot of blue, to no blue.
