The results show that the gill surface of all five species have frontal cilia,lateral cilia and laterofrontal cirri.

这5种蚌的鳃表面都有前纤毛、侧纤毛和前侧纤毛。

In addition,a new structure,frontal cirrus between the frontal cilia and laterofrontal cirri,is found only on the gill surface of Corbicula fluminea.

此外，仅在河蚬鳃表面前纤毛和前侧纤毛之间，观察到一种新的纤毛结构——前触毛。
