They have 5 hearts. =)
The function of an earthworm's nephridium is to excrete wastes from the earthworm's body.
I think the animal that has 4 hearts is a earthworm, because in my science class i dissected a earthworm, i saw 4 different parts of tiny black hearts as my teacher said they were, so yes i am learning in 7th grade but i did learn a lot about the earthworm including the hearts. so that proves that the animal that has 4 hearts is.... the earthworms.

The earthworm has five pairs of hearts, which would make a total of ten.
it acts as a heart for an earthworm.... <3
the brain is essential for the movement of the earthworm. If the brain of the earthworm is removed, the earthworm will move continuously without stop
