Abstract: Bristleworms assigned to Perinereis cultrifera can reproduce by epitoky or atoky according to the location of the populations. Variation in the number and distribution of paragnaths has been investigated in two populations of the atokous form from Algiers Bay and two populations of the epitokous form from the English Channel and the Algerian Mediterranean east coast respectively. Significant inter-population variation was revealed. The atokous forms from the bay of Algiers constitute an homogeneous group for all the paragnath groups whereas the epitokous forms from the English Channel and the Mediterranean Sea present a great heterogeneity in the number of paragnaths in most of the groups. The three distinc groups of populations identified during this study can be assigned to cryptic species.
