Lates calcarifer is serially hermaphroditic with males reaching maturity at 37 to 72 cm and changing into females starting at 73 cm, at around five years, three to five years, or six to eight years depending on the source Males mature at three to five years, but this study was conducted in cage farmed fish, which may have different maturation times than wild fish. Some male specimens do get larger than 73 cm. The transition from male to female is short, lasting as little as a week, and may not occur in all individuals.
