Dugesia japonica is a species of freshwater planarian that inhabits freshwater bodies of East Asia, including Japan, Korea, Taiwan, China and northeastern Siberia.[2] However, molecular studies suggest that Dugesia japonica is polyphyletic and different populations across its area of occurrence constitute distinct species.[3]
D. japonica position in relation with other Dugesia species after the work of Lázaro et al., 2009:[4]
A study was published in 2017 in which a Dugesia Japonica trunk fragment had been sent into space, and grew with two heads, one on either end of the trunk.[5] However, the influence of space conditions on this phenomenon is debated.[6]
