Summary:The reproduction of Nereid Perinereis cultrifera in the English Channel and the Atlantic is of an epitokous type. The same Nereid in the Mediterranean (Bay of Alger) has been described as atokous (Marcel, 1962) and since that time epitoky in mediterranean specimens has been considered to be an accidental phenomenon. However, in the present study polychaetes collected at Salammbô (near Tunis) show that those P. cultrifera reproduce exclusively by epitoky.
