While gathering shellfish is a popular pastime, the main business of Yandun Jiao happens further out at sea.

虽然采集贝壳类动物是流行的消遣，但烟墩角村的主要事业在更远的外海。

Did you know I'm allergic to shellfish?

你知道对贝壳类过敏吗？

Having nothing better to do, I decided to dredge these beautiful, clear waters, which exhibited a profusion of shells, zoophytes, and open-sea plants.

为目前没有什么可做的，就到要在这些清澈的海水中看，好像水里面有丰富的贝壳类、植虫类和海产植物。

Heating shellfish in water forces the shells to open, making it easier to get at the contents, but also, and no less importantly, it sorts out which ones are bad-bad ones stay closed.

把贝壳类水煮一下，壳就打开了，吃里头的肉就轻而易举。而且，同样重要的是，人类是摸着石头过河，一路试吃试过来的。

In order to stay alive, animals need to have keen senses. Fish and some shellfish have sharp eyes. Almost all animals are sensitive to touch. Fish detect movements in the water by means of their lateral lines.

为了生存下来，动物需要有敏锐的感觉。鱼和一些贝壳类动物有敏锐的眼睛，几乎所有的动物对触觉都很敏感。鱼依靠侧线来察觉水中的活动。
