[Anterior and caudal regeneration in the proterandric polychaeteOphryotrocha puerilis Clap. Mecz].

Abstract

Only when a part of the prostomium remains in situ does complete anterior regeneration take place.The course of caudal regeneration is the same both in males and females whether they have their prostomia in situ or not. The more segments are amputated the more will be regenerated.The amputation of posterior segments which releases the regeneration, or regeneration itself, may influence the sex of regenerating worms for a short time.
