This is a dichotomous key which is a way of finding the scientific name of an organism based on their characteristics.  To use this, first you must choose an organism.  Then you start at number one and choose whether A or B describes your animal, you then follow the line and go to the statement in which it tells you to go.  Follow this same process as many times as necessary until the line leads you to a name.  This is the scientific name of your species!
