Q-Man asks:
        Hecky darn; I may have mentioned this before. Sometimes my
memory is just a memory.
    BUT critters in the tropics are more colorful than critters near the
poles. This goes for birds, shells, fish, etc.
    What is the scientific explanation? Why do northern climates appear
hospitable to only white, black and gray? Why are colorful critters
unable to survive farther north? Well, you get the idea.
