Question 1
What shape is the flatworm's body?
Look at the animal's outline when its body is extended. It may be oval, broad and almost circular, or very long and narrow like a ribbon. Its shape may change as it moves. Select several options if they clearly apply to the animal. If you cannot distinguish its outline, skip the question.
