魚會(huì)淹死嗎？這個(gè)問題看來很荒謬，因?yàn)轸~本來就是生活在水中的，怎么會(huì)淹死呢？不過答案卻是肯定的，只不過魚是“淹死”在氧氣中的。

Can a fish drown?

YES!

Fish, like people, need oxygen to live.

A fish out of water is a fish out of its element. A fish comes fully equipped with a pair ofgills, which it uses to breathe under water. The gills extract life-sustaining oxygen from thehydrogenin the watermolecules, in order to regulate the amount of oxygen intake. This maintains the necessary balance of the two components of water for the fish to survive.

When a fish is taken out of water, and exposed only to air, not to oxygen and hydrogen containing water, its gills are unable to control the oxygen intake, the delicate balance cannot be maintained, and the gills inhale alethaloverdose of oxygen. The fish essentially experiences death by "drowning."
