Invasive "jumping worms" threatening plants, forests and wildlife in dozens of states: "These are earthworms on steroids"

A ravenous species of earthworm has arrived in Connecticut with the potential to cause all sorts of damage to plants, forests and wildlife. The so-called jumping worms have already been found in over 30 states.

Jumping worms can destabilize the soil and make it harder for some plants to grow, Connecticut state scientist Gale Ridge told Hearst Connecticut Media Group. They also can accumulate toxic metals like mercury and lead, which are then eaten by birds and other animals.

They don't actually jump, but have strong, rigid bodies that can whip violently if they are disturbed. They also can climb, and have been found in the upper stories of buildings.
