Etude de la microstructure des soies de polychètes Capitellidae et Oweniidae au microscope électronique à balayage: un critère systématique précis

Seanning electron microscopy proves to be an ideal technique for the examination of microstructures ornamenting the apex of the hooks of some sedentarian Polychaeta (e.g. Capitellidae, Oweniidae). As these microstructures are considered to be very precise systematical criteria for certain groups, good topographical charts of them allow us to group or, on the other hand, to separate polychaete species sampled in the Mediterranean Sea and Mozambic Channel (coasts of Madagascar), or again to identify different forms among species reported as cosmopolitan.
