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.
