Fish

• All fish are vertebrates(脊椎動物) meaning they have backbones.
• All fish hatch from eggs.
• All fish use gills(えら) to take water out of oxygen.
• All fish are cold blooded, which means their body temperature is tied to the water around them.
• Fish sleep with their eyes open.
• Goldfish turn white if they aren't exposed to the Sun.

魚は目を開けたまま寝るとか太陽に当たらないと金魚は白くなるとか知らなかった。
だいぶ前ケアンズでシュノーケルした。引き潮時、魚の大群に遭遇した。

少し怖かったけど感激！！
