Good stuff!!! That pretty much goes along with what I said in the beginning.

There is no doubt that sharks do not perceive color the way we do, the truth is few animals do. What they do definitely see is the amount of light reflected off the object, how it contrasts to the background light, and different colors reflect different spectrum of light or essentially different amounts of light in relation to various backgrounds.
