这只金鱼的全身由许多铰链连接，因此可以灵活运动。

需要注意的是，正如实拍图所示，这只金鱼仅展示了上半部分，并不是一条对称的金鱼的一半。因此，你无法通过打印两次将其拼合成一条完整的金鱼。

当然，如果大家更喜欢完整的金鱼，我后续也可能会制作一些可以拼合成完整金鱼的3D模型。敬请期待！

This goldfish's entire body is connected by many hinges, allowing it to move flexibly.

It's important to note that, as shown in the actual photos, this goldfish only showcases the upper half and is not a symmetrical half of a complete goldfish. Therefore, you cannot print it twice to assemble into a complete fish.

Of course, if everyone prefers a complete goldfish, I may consider creating some 3D models that can be assembled into a complete fish in the future. Stay tuned!
