Hybrid form Bythotrephes arcticus x Bythotrephes cederströmii In samples from the delta of the river Severnaya Dvina (north of European Russia), Litvinchuk (2002: P. 85, Fig. 15, 2007) found, among many individuals of B. arcticus (syn. B. crassicaudus Lilljeborg), one adult female of the interspecif...
