Description of the three stages of juvenile gill development based upon observations during this study.

The age (months) at which individuals begin to display particular structures/developments is approximate and no attempt has been made to postulate when development of certain structures begins if they were not directly observed during this study. The number of inner demibranch (ID) and outer demibranch (OD) filaments are the number observed during this study and may differ depending upon population or other parameters.

个体开始呈现特定结构或发育状态的月龄为近似估值；若本次研究未直接观测到某类结构的发育过程，则未对其发育起始时间作出任何推定。本次研究观测得到的内半鳃（inner demibranch, ID）与外半鳃（outer demibranch, OD）鳃丝数量，可能因种群差异或其他参数而存在差异。
