Unlike other molluscs, bivalves lack a radula and feature labial palps, which carry food from the gills to the mouth.

与其他软体动物不同的是,双壳贝缺乏齿舌,具有唇瓣,可将食物由鳃送到口部.

The mandibles are usually lost, the labrum is reduced to a narrow transverse sclerite, and the labium is a small flap ( though its palps retain quite large).

上颚消失，上唇退化为一条窄横片，下唇退化为一小片（下唇须发达）。

But with new exploit of astrospace, our form are more punily,when we can meet a few ants which can touch palps then look at each other a long time and eventually embrace each others tightly?

但是随着宇宙空间的新开拓，我们的体型更加微小了，什么时候，还能碰见几只可以碰一下触须，然后对视良久，终于紧紧拥抱的蚂蚁？
