Slide 2:
True cave dwellers are blind. They have no need for eyes. They have no need for color, so many are clear or white.
White crickets and white centipedes feel their way in the dark, searching for food. Hungry blind beetles scratch in the loose earth. Spiders hunt on foot. White crayfish creep through pools and streams. Blind fish no bigger than your hand are clear enough to see through.
Life in a cave is a constant search for something to eat. Sometimes floods carry in fresh supplies. Weeds and roots, leaves and twigs, and tiny animals from the soil are all food for hungry dwellers in the dark. Not a speck is wasted.
