For oviposition the radula cuts round holes a few mm from each other in an ascidian. The foot positions large, spherical, pot-shaped egg capsules in the holes. Only the transparent plug in the opening of the capsules is visible on the surface. Each capsule contains hundreds of unshelled ova in an albuminous fluid. The plug is freed from the opening for the planktonic bilobed veliger larvae to escape.
