A Fish Tale
Twenty-five years after its first discovery on the Great Barrier Reef in Australia, the world's smallest fish has now been recognized and given a name: the stout infantfish. The male is about 1/4-inch long (i.e. the width of a pencil), while the female is a mere 1/18-inch longer. Not the most attractive of animals, they are toothless, scaleless, colorless...except for black eyes, and have a life span of only two months.
Question 1: How many of these fish would fit in your school gymnasium? A million? A billion? A trillion?...
Question 2: Knowing that about 500,000 of these fish would weigh one pound, what would your gymnasium full of these fish weigh?
