France – Asian Worm Invasion
A silent invasion of giant hammerhead flatworms has been occurring for the past two decades in France and some of its territories.
The extent of the invasion was uncovered by citizen scientists, who found that several non-native species now slither across urban areas of southern France and its overseas territories from the Caribbean to Oceania.
The ecological impact of the invasion is unclear, but the worms prey on animals living in the ground, including earthworms.
The Asian natives are believed to be inadvertently spreading through international trade.
