胚胎形成的

The outside gill disappeared, the gill arches developed to from the branchia, later the branchia appeared primary protuberance, along with developing, it appeared the secondary protuberance and the third protuberance, until the 36 stage, the stage is the inside gill developing at the peak, later it came into the period of the metamorphosis, the inside gill degenerated, the third protuberance began shrank, next the secondary protuberance and the primary protuberance shrank, finally the gill arches shrank and disappeared, the metamorphosis completed.

内鳃的发育是首先由鳃弓上的突起形成鳃叶，其次鳃叶上出现初级突起，随着进一步发育出现次级突起和三级突起，直到内鳃发育最高峰(胚胎发育的36期)。随后进入变态期，内鳃开始退化，首先是三级突起开始萎缩，其次是次级突起和初级突起，最后是鳃弓，直至鳃弓完全消失，变态完成。
