Did you know I'm allergic to shellfish?

你知道我对贝壳类过敏吗？

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

我因为目前有么可做，就到要在这些海水中去捞捞看，好像水里面有丰富贝壳类、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，吃里头肉就轻而易举。而且，同样重要是，人类是摸着石头过河，一路试吃试过来。

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，动物需要有敏锐感觉。鱼和一些贝壳类动物有敏锐眼睛，几乎所有动物对触觉都很敏感。鱼依靠侧线来察觉水中活动。
