First record of Boccardia polybranchia (Haswell,1885) (Polychaeta: Spionidae) from the Atlantic coast of Morocco

The polychaete boccardia polybranchia (haswell,1885),spionidae,was found for the first time in atlantic moroccan coasts. this species was collected from a rocky intertidal habitat in the region of safilocated in western morocco (32°15'23.52 n and 9°15'42.36 w). this new occurrence from this rocky shore extends the known geographical distribution range of the species both in morocco (as the southern limit of the north atlantic) and in north africa. it contributes to the growing body of knowledge of the biogeography of this species found,to date,on many coastal geographical regions between the north (the manche and the english channel) and the south (south africa and southern america) including the indian ocean. some data on the spatial distribution,relationship with sewage organic enrichment,morphology and ecology of the species are discussed. © 2017,university of mohammed premier oujda morocco.
