The tropics Many different kinds of fish live in the sea in parts of the world called the tropics. The tropics are a warm area near the equator. The equator is an imaginary line that goes around the middle of Earth. There are rain forests on the land and coral reefs in the ocean in the tropics. The fish that live in the tropics are called tropical fish. The northern edge of the tropics is an imaginary line called the Tropic of Cancer, The equator divides Earth in half. The southern edge of the tropics is an imaginary line called the Tropic of Capricorn.

许多不同种类的鱼生活在世界上被称为热带地区的海里。 热带是赤道附近的一个温暖地区。 赤道是一条假想的绕着地球中心的线。 热带地区陆地上有雨林，海洋里有珊瑚礁。 生活在热带地区的鱼叫做热带鱼。 热带的北部边缘是一条虚构的线，叫做北回归线。赤道把地球分成两半。 热带的南部边缘是一条虚构的线，叫做南回归线。

Many fish and other animals in the tropics live in coral reefs. These reefs are like underwater cities where fish swim among the coral (rocky structures formed by millions of tiny animals). Coral grows in many colors, shapes, and sizes. It's a fact! Some coral reefs are dying because the sea water is getting warmer. We can help protect the reefs by not damaging the air, water, and land around us.

热带地区的许多鱼类和其他动物生活在珊瑚礁中。 这些珊瑚礁就像水下城市，鱼类在珊瑚(由数百万小动物形成的岩石结构)中游泳。 珊瑚有许多颜色、形状和大小。 这是事实!一些珊瑚礁正在死亡，因为海水正在变暖。 我们可以通过不破坏周围的空气、水和土地来帮助保护珊瑚礁。

Clownfish Colorful clownfish live around sea anemones in coral reefs. A sea anemone is a kind of sea animal that looks like a plant. Clownfish are found in the warm waters of the Pacific and Indian oceans. The largest clownfish grow from 4 to 6 1/2 inches (10 to 17 centimeters) long. Clownfish are partners with sea anemones. The anemone uses its feelers to sting other animals. But the feelers do not hurt the clownfish. Staying close to the anemone protects the clownfish from being eaten by other sea animals. In return, the clownfish helps clean the anemone. Clownfish have a bright orange body with white stripes outlined in black.

五颜六色的小丑鱼生活在珊瑚礁里的海葵周围。 海葵是一种看起来像植物的海洋动物。 小丑鱼生活在太平洋和印度洋的温暖水域。 最大的小丑鱼长4到6.5英寸(10到17厘米)长。 小丑鱼是海葵的伴侣。 海葵用触角蜇其他动物。 但是触角不会伤害小丑鱼。 靠近海葵可以保护小丑鱼不被其他海洋动物吃掉。 作为回报，小丑鱼帮助清洁海葵。 小丑鱼的身体是亮橙色的，上面有黑色的白色条纹。

A coating on the clownfish's skin protects the fish from being stung by a sea anemone. It's a fact! Clownfish can scare away other animals by slamming their teeth together!

小丑鱼的皮肤上有一层保护膜，可以保护它不被海葵蜇伤。 这是事实!小丑鱼可以通过咬牙把其他动物吓跑!
