丝背细鳞鲀 Aug 18, 2010

我看到一些条大概十公分长的"丝背细鳞鲀"。它赶快游泳得很快，一会儿忽地停止，一会儿又蠕游泳起来。这种鱼游泳得很好，因为它的鳍微微地十分灵活。

I found Thread-sail filefish, about 10 cm long. It swam quickly, stopped suddenly and started swimming slowly again. It can swim very well because the fins work in high speed finely.

我看到一些（几条？一条？）丝背细鳞鲀，大约10公分长。它能游得很快，然后突然静止，接着又慢慢地游起来。它们的背鳍在高速游动时也能运动得很好，所以在水里才能这么灵活。

我看到些条大概十公分长的"丝背细鳞鲀"。它游的很快，突然停下来并开始游的很慢。它能游得很好，是因为它的鳍处于很高的速度。

最后一句我猜你想说，整个鱼鳍都很灵活。（我很奇怪你为什么用微微）。
