A bizarre invasive worm with its mouth in the middle of its belly has been found in the United States for the first time, according to new research.
The New Guinea flatworm (Platydemus manokwari) is only a couple of millimeters thick but grows to be up to 2.5 inches (65 millimeters) long. As its name suggests, the worm is a New Guinea native, but it has been spreading across the globe, hitching rides on exotic plants and in soil.
