The scallop family is unusual in that some members of the family are dioecious (males and females are separate), while others are simultaneous hermaphrodites (both sexes in the same individual), and a few are protoandrous hermaphrodites (males when young then switching to female). Female scallops have red roe and male scallops have white roe, corresponding to ova and spermatozoa respectively, which are released freely into the water during mating season and fertilized ova sink to the bottom.
