It is short in predacious forms, sometimes no longer than the body cavity, but long in herbivorous forms, being coiled and several times longer than the entire length of the fish in some species of South American catfishes. The larger its internal surface, the greater its absorptive efficiency, and a spiral valve is one method of increasing its absorption surface. Birds have evolved a variety of beak types that reflect the vast variety in their diet, ranging from seeds and insects to fruits and nuts. It will show you how similar we are to animals and how different animals can be when it comes to just three of the many organ systems of our body.
