Worms that contain the same lethal neurotoxin as puffer fish are invading the East Coast

• Hammerhead worms are turning up all over Washington, DC and northern Virginia, the Washington Post reported.
• The worms carry the same toxins as puffer fish though a single worm probably couldn't kill a human.
• The Hammerhead worm population will only grow as the climate continues to warm, researchers say.

An invasive, toxic worm has been found all over the Mid-Atlantic region — and they could invade the whole East Coast in the coming years thanks to a warming climate, experts say.

Researchers have spotted the hammerhead worm hundreds of times in the area of Washington, D.C. and northern Virginia over the last 15 years, the Washington Post reported.
