B1, B2 details of part duct when closed (B1) and open (B2), showing how contraction and relaxation of muscles of egg-laying duct resulut in coordinated opening and closing of the gonopores and seminal ducts (black arrows), allowing release of gametes (open arrows) (the shell ducts, which open into the egg-laying ducts, are not shown on diagram). |
