An apparatus and related method for removing gonadal sacks from the interior walls of sea urchin shells. The apparatus comprises an elongated flat blade having a longitudinal knife edge, flexible in a direction out of its plane, the blade extending outwardly from the end of a post in a direction normal to the longitudinal axis of the post, and means associated with the blade and post when the blade and corresponding end of the post extend into the shell of the sea urchin to cause them to rotate through 360.degree. in the direction of the knife edge about an axis and, when positioned proximal to the inner of the shell, cause the blade to sever tissue and tendons bonding the gonadal sacks to the interior wall to release them from that wall.
