You've seen one fish......you've seen them all?
Fish are amazingly diverse in their morphology. Some primitive species, such as the lampreys, lack jaws, scales and paired fins. Others, like the sharks do not have bones, but possess a cartilaginous skeleton instead. They come in all shapes and sizes, from the expected, to the bizarre. Form and function work together and examination of basic body shapes gives us insight to fish lifestyles.
Most fish fall into one of six basic body forms: the rover predator, lie-in-wait
predator, surface oriented, bottom dweller, deep-bodied or eel like.
