The worms produce sexually by laying eggs and asexually by fragmenting and growing new heads and tails when cut into pieces. Hammerhead worms leave a mucus trail and excrement that help it glide along, McGowan previously said in a MU Extension article. “They’re surviving our winters they’re reproducing, and their population is starting to grow,” McGowan said. “I’m suspecting these were accidentally introduced here in soil, in plants that have been potted up in other states and then shipped here, and those worms hitched a ride,” McGowan said.ĭespite not being from the Ozarks, the hammerhead worms are adapting and acclimating. When speaking with folks who spotted the invasive planarians, McGowan said many had recently brought in a load of soil or had purchased nursery plants. There could be negative consequences, but it's still unclear, McGowan said.

A family recently discovered a hammerhead worm on their property in southeast Springfield.
