You're a Jellyfish!

《你是一只水母》 文字：基拉·弗里德 插画：辛迪·希尔

Floating at Sea Imagine that your body is shaped like a bell and you have long tentacles streaming down under you. You are mostly made of water and cannot survive away from it. You live in the ocean and travel by floating gracefully on currents. You're a jellyfish or jelly and not a fish at all. You're a kind of invertebrate, an animal that has no backbone.

漂在海面上 想象一下，你的身体呈钟形，身下拖着长长的触手 你的身体大部分都是水，离开水就活不下去 你住在海洋里，顺着洋流优雅地漂来漂去 你是水母，根本就不是鱼类 你属于无脊椎动物，也就是没有脊椎的动物

You and your jellyfish cousins live in every ocean in the world. Some also live in lakes and ponds. Some live in warm water, and others prefer cold water. Some of your cousins are survivors. They've been around for 650 million years, since long before the time of dinosaurs.

你和你的水母亲戚住在全世界的每一片海洋里 有些水母还住在湖泊和池塘里 有些住在温暖的水域，另一些更喜欢冷水 你的有些亲戚可是生存高手 它们已经存在了6.5亿年，远在恐龙出现之前就生活在地球上了

Jelly Bodies Like all jellyfish, you have no brain, heart, blood, or bones. Your body is made of water, muscles, and nerves. You use your eye spots and nerve network to sense up and down, light and dark, and the world around you. The main part of your body is your bell. Tentacles hang from around your edges like fringe. A mouth and digestive sac hang in the center. Some of your cousins have frilly oral arms or mouth arms around this sac.

水母的身体 和所有水母一样，你没有大脑、心脏、血液也没有骨头 你的身体由水、肌肉和神经组成 你靠眼点和神经网感知上下、明暗和周围的世界 身体最主要的部分是你的钟状体 边缘垂着触手，就像一圈流苏 嘴巴和消化囊挂在身体正中央 有些亲戚在消化囊周围长着褶皱的口腕

You and your cousins come in many shapes, sizes, and colors. Jellyfish that live near the ocean surface are often clear or see -through. Jellies that live deep in the ocean may be red or purple. Some jellies are white with splashes of color. Some deep sea jellyfish even glow in the dark.

你和你的亲戚们有各种各样的形状、大小和颜色 住在海面附近的水母通常是半透明的 深海里的水母可能是红色或紫色的 有些水母是白色带彩色斑块的 有些深海水母甚至还会在黑暗中发光

Getting Around As a jellyfish, you spend most of your time drifting on ocean currents. But you can also move when you want to. First, you let your bell fill with water. Then you squeeze the muscles in your bell the way a person blows a bubble with bubble gum. As you force water out of your bell, you shoot forward.

四处移动 作为一只水母，你大部分时间都顺着洋流漂流 不过你想动的时候也可以移动 首先，你让钟状体吸满水 接着你收缩钟状体的肌肉，就像人们吹泡泡糖吹泡泡那样 把水挤出去之后，你就向前冲出去了
