Perfluorooctane sulfonate (PFOS) which has been distributed worldwide is a persistent organic contaminant. Blueberry anthocyanins (ANT) are phytonutrients with antioxidant activities. The influence of different PFOS and ANT concentrations on the behavioral activities, regeneration of planarians (Dugesia japonica), and the expression levels and contents of Djnad6 and Djcox1 genes has been investigated. PFOS treatments affected the gene expression levels, induced a decrease in the planarians’ locomotor velocity, and increased the time required for the regeneration of the transverse amputated fragments in a time- and dose-dependent manner. Additionally, ANT treatments, to a certain extent, alleviated the damage caused by PFOS to planarians. ANT increased the planarians’ locomotor velocity and the percentage of regenerating planarians with eyespots and auricles. Furthermore, ANT alleviated the expression disorders of Djnad6 and Djcox1 induced by PFOS.
