A fish is a water-dwelling animal that breathes through gills and has a backbone, fins and a two-chambered heart. If you're the incurious sort, that may be all you care to know about them -- other than perhaps which ones taste better with cocktail or tartar sauce. But for those of us who fancy fish, they're endlessly fascinating creatures, about whom we can't learn enough

They range from tiny creatures that would fit on a fingernail to monsters the size of cabin cruisers. They can sleep with their eyes open, taste without using their mouths and float without casting a shadow. Learn more fun fish facts on the following pages.
