It is distributed all across the world.[3] However the authenticity of this is hard to tell. It has been reported in the continents of Europe, Africa, Asia, South America, Australia,[7] and North America.[4]

It has been reported in Japan, Russia, New Zealand, Kenya,[7] Venezuela, Argentina, and Mexico.[5] Genetic evidence indicates this species was introduced by humans.[8][clarification needed]

It is the only known species of fresh water Nemertea in Australia.[9]

It is rarely found in the United States.[3] But in the state of Connecticut it lives in freshwater habitats. Here it usually lives among algae, plants, or detritus. It is more numerous during the Fall season.[6]
