Toxic Hammerhead Worms Invade East Coast, Caution Urged
Invasive hammerhead worms, spotted more frequently in the D.C. region, are causing concern due to their secretion of potent toxins, including tetrodotoxin found in puffer fish. University of Maryland Professor Michael Raupp warns that handling these worms with bare hands can cause skin irritations, and domestic animals that come into contact with or consume them may experience discomfort or illness. The cannibalistic worms immobilize their prey with sticky slime and consume body fluids and tissue. The U.S. Department of Agriculture lists the hammerhead worm as a predator of earthworms, potentially impacting agricultural, horticultural, and natural ecosystems.
