    Some interesting facts about fish:

    Fish have been on the earth for more than 450 million years.

    Fish were well established long before dinosaurs roamed the earth.

    There are over 25,000 identified species of fish on the earth.

    It is estimated that there may still be over 15,000 fish species that have not yet been identified.

    There are more species of fish than all the species of amphibians, reptiles, birds, and animals combined.

    40% of all fish species inhabit fresh water, yet less than .01% of the earth's water is fresh water.

    The Spotted Climbing Perch is able to absorb oxygen from the air and will crawl over land using its strong pectoral fins.

    Some fish like sharks do not posses an air bladder to help keep them afloat and must either swim continually or rest on the bottom.

    Some fish make sounds by grating their teeth and others like some catfish make sounds from their air filled swim bladder.

    Some species of fish can fly (glide) others can skip along the surface and others can even climb rock.

    Fish have a specialized sense organ called the lateral line, which works much like radar and helps them navigate in dark or murky water.

    The largest fish is the great Whale Shark, which can reach fifty feet in length.

    The smallest fish is the Philippine Goby that is less than 1/3 of an inch when fully grown.

    Some species of fish have skeletons made only of cartilage.

    Fish have excellent senses of sight, touch, taste, and many possess a good sense of smell and 'hearing.'

    Fish feel pain and suffer stress just like mammals and birds

    Also,
    Saltwater fish take in liquid like we do...and freshwater fish pull it in thru their scales!
