Our Key system will help you decide what plant or animal you have seen. It works like "20 questions"... Is it a plant or animal? If an animal, is it a chordate? a mollusc? ... and so on. Along the way, you will see representative pictures of each of your choices. You will have easy access to definitions of terms. You always have a chance to go back, if you change your mind on a previous answer. And you'll be able to click on pictures and links to learn more.
