随着变态发育，大菱鲆仔鱼有眼侧皮肤与无眼侧皮肤结构上出现差异。

With the process of metamorphosis , the ocular side skin and blind side skin became different in ultrastructure .

因此，圆背角无齿蚌的变态发育包括两个明显的阶段：第一阶段为寄生变态期；

Accordingly , metamorphosis development of A. wp includes two identical phases : the first is parasitic metamorphosis phase ;

圆背角无齿蚌在变态发育过程中其外部形态、内部器官、营养源发生了较大变化：成熟的钩介幼虫仅仅可以作简单的双壳开合运动；

During metamorphosis development , A. wp would change greatly in the external form , internal tissues and nutrient source .
