Leopard Flatworms are very simple creatures. They have a very simple nervous system with two nerve cords running down either side of their bodies and connector nerves in-between the two, making it look like a ladder. It has two simple brains called ganglia, which are simple bundles of nerves. The Leopard Flatworm has two eyespots that help it sense light. This is all that these simple creatures have in regards to their nervous system, but it is enough to survive.
