C 跨学科 灯笼鱼的外形特征及生活习性(2025·天津中考)
Lanternfish(灯笼鱼) are fish that carry their own lights. Most lanternfish are brown on top and silver underneath(在下面). They have very large eyes. They eat small sea animals.
If you want to find them, you must go deep into the sea. As you go deeper and deeper, the daylight(日光) becomes $\underline{\mathrm{dimmer}}$ and dimmer. At over 152 metres below the surface(表面) of the water, the daylight is almost gone. The water is dark blue. There you will find lanternfish.
There are over 230 different kinds of lanternfish in the world. Most lanternfish are just as long as your fingers. Even the biggest lanternfish are only about 15 centimetres(厘米) long. They are not large in size.
However, each lanternfish has about 100 small round lights on the lower part of its body. The fish use their lights to help them catch food. They also use their lights to send information so that they can recognise(认出) each other. At night, they may swim up near the surface of the sea. Their lights shine like stars under the water.
Lanternfish are one of the wonders of the sea.
