Other possibility though, which is much more interesting, is looking at bivalves, particularly mussels.

一种可能选择就更有意思了， 就是双壳贝类， 尤其是贻贝。

It's more of an issue with bivalves, like muscles and oysters, which we eat whole.

这对双壳类动物来说更像是一个问题，比如们整只的肌肉和牡蛎。

Captain Nemo was obviously familiar with this bivalve's existence. This wasn't the first time he'd paid it a visit, and I thought his sole reason for leading us to this locality was to show us a natural curiosity.

尼摩船长分明是知道这只双壳动物的存在。到这个地方来不止一次了，想们到这里来只是要给们看一件天然的奇物。

Bivalve shells are made to open and shut, but on what a number of patterns is the hinge constructed, from the long row of neatly interlocking teeth in a Nucula to the simple ligament of a Mussel!

双壳贝壳是用来打开和关闭的， 但是铰链的构造有多少种模式， 从 Nucula 的一长排整齐互锁的牙齿到贻贝的简单韧！
