Eggs of S. lessoniana laid on tree branches sunk in a local harbor by the local fishermen to enhance egglaying and stock recruitment to their fishing area. These eggs are back illuminated by a camera flash showing their characteristic form. Each circular shape down the length of each individual egg strand or finger is a single embryo defined by the circumference of the chorion. In this species, egg fingers usually have 5-9 embryos per finger.
