Usually plants are animals’food. For instances, sheep feed on grass,elephants take in leaves. But we live in a wonderful world that will shock you from time to time—some animals would fall prey to plants.They are carnivorous plants,plants that eat insects and small animals. Here are four carnivorous plants.

Cobra Lily

Just like its name indicates, this plant looks like a snake and it can produce some kind of fluid that is sticky.When insects try to eat its nectar, the fluid will help the plant trap them and make them its delicacy.

Sundew

Sundews have needles with sticky droplets. Insects are attracted to them. They get stuck in the goo and become Sundews’food.

Venus flytraps

Venus flytraps have jawlike leaves. The jaws usually keep open. When flies or other insects happen to touch the leaves, the jaws close immediately. The leaves have spiky hairs like men’s beard which form a closed door when the jaws close. Bye-bye, fly!

Pitcher Plant

This plant got the name for its shape. People think it looks like a water pitcher or some kind of container. It has a big mouth. When small animals look inside for food, they might fall in and can’t escape. The plant digests them.

植物往往作为动物的食物存在。比如,羊吃草,大象吃树叶。但是我们的世界很精彩,总会给你惊喜——有些动物会成为植物的猎物。这些植物就是“肉食”植物,它们以昆虫和小动物为食。下面介绍四种“肉食”植物。

Cobra Lily(眼镜蛇百合)

就像它的名字所显示的那样,这种植物长得像蛇,它能分泌一种黏糊糊的液体。当昆虫吃花蜜时,黏液会帮助植物捕捉昆虫当“下酒菜”。

Sundew(茅膏菜)

Sundews 长有针状物,针状物的末端分泌黏性的水珠。昆虫会被这些黏性水珠吸引、困住,成为Sundews 的食物。

Venus flytraps(捕蝇草)

Venus flytraps 的叶子像嘴巴,平时张开。一旦苍蝇或者其他昆虫触碰到叶子,嘴巴立即关闭。叶子上像男人胡子的利刺儿会形成一道关闭的门。再见,苍蝇!

Pitcher plant(瓶子草)

这种植物因外形而得其名。人们觉得它像水壶或者某种容器。这种植物有一张大嘴。当小动物寻找食物时,会掉入容器中无法逃脱,并最终被植物消化掉。
