Maritigrella crozierae
Maritigrella crozierae is more commonly referred to as a Tiger Flatworm. Tiger flatworms are very thin and dorsally flattened. They are bilaterally symmetrical. The polyclad contains a cerebral ganglion knot in the anterior region, in which all nerve signals are received. The flatworm has mechanoreceptors along the epidermis to analyze its environment, as well as photoreceptors on eyespots in the anterior region to sense light. Because its eyespots, or ocelli, are extremely simple and have trouble seeing anything besides the direction and intensity of light. Chemoreceptors are highly utilized by the flatworm to sense food and mates. The tiger flatworm moves through smooth undulations of its body, by using muscles and body fluid that is kept under pressure.
