Most studies on annelid collagens have concentrated on the cuticle, whereas little is known about interstitial collagen, notwithstanding the particular position of this phylum in the evolutionary trend. In fact, the annelids differentiate themselves from lower groups in being coelomate and segmented. Metamerism involves a new type of locomotion based on the presence of intermuscular septa dividing the coelom, and of powerful muscles strengthened by connective tissue lamellae (Fretter and Graham, 1976). For this reason, the connective tissues of the annelids are very well developed and the presence of collagen fibrils with a periodic structure has been recognized since Astbury’s first studies (1961) (for review of the literature, see Murray and Tanzer, this volume). In spite of this, detailed morphological and biochemical characterizations of interstitial collagen are still lacking.
