Their movement is another factor contributing to their alien-like aura. They glide over surfaces in a fluid, snake-like manner, using cilia on the underside of their bodies to propel themselves. This smooth, sinuous movement is quite different from the segmented, contracting motion of earthworms, adding to their bizarre appeal.
4. Where Hammerhead Worms Come From and How They Spread
Hammerhead worms are native to Southeast Asia but have become invasive in many other parts of the world, including North America and Europe. They are often inadvertently introduced to new areas through the importation of plants and soil, as they can survive being transported in moist soil environments.
Once established in a new location, hammerhead worms can spread rapidly due to their reproductive strategy. They reproduce asexually by fragmentation, meaning a single worm can break into multiple pieces, each of which can develop into a fully formed worm. This method of reproduction, combined with their lack of natural predators in many new environments, allows their populations to grow quickly.
