Skesodara has several eggs in the ovaries, and during the spawning season, eggs are periodically matured and spawned, and spawned many times during the spawning season. Due to changes in the environment such as seawater temperature, or physiological abnormalities of the fish body due to malnutrition, etc., it seems that the egg tissue that was not spawned was covered with a new egg tissue before it collapsed or absorbed.
