They have 5 hearts. =)
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 function of an earthworm's nephridium is to excrete wastes from the earthworm's body.

Earthworms do not have hearts in the traditional sense; instead, they possess a series of muscular structures called aortic arches. These aortic arches function similarly to hearts by contracting to pump blood throughout the earthworm's closed circulatory system. The blood is circulated through vessels, delivering nutrients and oxygen to the worm's tissues.
The earthworm has five pairs of hearts, which would make a total of ten.
it acts as a heart for an earthworm.... <3
