A toxic, predatory invasive worm capable of unlimited self-cloning has arrived in Maine. The first sightings were reported last fall from southern and central parts of Maine of the hammerhead worm, a flatworm that can range from 8- to 15-inches long and is distinguished by the unique hammer or shovel-shaped head. The discovery is bad news for Maine’s gardeners since hammerheads prey on earthworms, which contribute to the health of Maine soil by turning organic materials into useful compost. Earthworm activity also helps aerate the soil, which increases soil nutrients and moisture intake. The hammerhead worm has no known predators.
