7. Butterfly Species My species is a butterfly species because it is important for keeping crustacean populations from growing to high. Also if they died off sharks would lose a source of food. Also humans would not be able to hunt them any more. Humans would not be able to use their oils any more. And this is why I think Smalltooth Sawfish are a butterfly species.
