Flatworms can reach a maximum size of around 40cm. Whilst this is big for a worm, there are certainly larger animals on earth. What might it be that restricts the flatworms body size?
A.
They have an exoskeleton that restricts their growth.
B.
They do not have a circulatory system.
C.
They are exothermic animals that have limited energy for growth.
D.
They are acoelomates and so the growth of their internal organs is restricted by growth of the outer body wall.
