It is dark brown on the upper surface, with a lighter central line. Near the tip of the head end are two eyes. Both ends of the animal are pointed, but the head end is more pointed than the tail end. Its body, however, is quite flat, being less than 2 millimetres (0.08 inches) in thickness. It is relatively large, about 40–65 millimetres (1.6–2.6 inches) in length and about 4–7 millimetres (0.16–0.28 inches) wide. manokwari is pale finely mottled light brown.

It has become established in a wide variety of habitats. It eats a variety of invertebrates including land snails, and has had a significant negative impact on the rare endemic land snail fauna of some Pacific islands. It was also deliberately introduced into two Pacific islands in an attempt to control an invasion of the giant African land snail. Native to New Guinea, it has been accidentally introduced to the soil of many countries, including the United States. Platydemus manokwari, also known as the New Guinea flatworm, is a species of large predatory land flatworm.
