0Octopuses are very smart.
They can solve puzzles, open jars, and even escape from tanks. In one lab, an octopus learned to turn off a light by shooting water at it. Why? Because the light annoyed it.
Octopuses also have a good memory. They can recognize different people. Some have even squirted water at people they didn't like.
And here's the funny part: they have nine brains. One main brain in their head, and eight smaller brains — one in each arm. That means each arm can think a little bit on its own.
So if you ever see an octopus in an aquarium, be nice. It might be watching you back.
章鱼非常聪明。
它们能解谜题、打开罐子，甚至从水缸里逃出来。在一个实验室里，有只章鱼学会了朝灯喷水来关掉它。为什么呢？因为那盏灯让它烦。
章鱼还有很好的记忆力。它们能认出不同的人。有些章鱼甚至会朝自己不喜欢的人喷水。
有趣的是：它们有九个大脑。一个主脑在头部，另外八个较小的脑——每个触手里各一个。这意味着每只触手都可以自己稍微思考一下。
所以，如果你在水族馆里看到章鱼，对它友好一点。它可能也在看着你。
