沙漠中也有鲜鱼活虾,这并非“天方夜谭”。澳洲西部是片大沙漠,干旱少雨,水坑中即使有水,含酸量也极高,很少有生物能够生存。但是,就在这片沙漠里,却奇迹般生活着一种“蝾螈鱼”。原来,当水坑干涸时,“蝾螈鱼”全部钻进地下较潮湿的地方,待水坑里有水后,再出来活动。为了适应环境,它能用皮肤呼吸,并磨炼出了长期忍饥挨饿的超凡本领。沙漠中不仅有鱼还有虾。美国科学家在美国的一个大沙漠中

Even with water in the puddle, the acid content is extremely high and few organisms can survive. However, in this desert, it miraculously lives with a kind of “salamander fish.” It turned out that when the puddle dried up, “salamander fish ” all drilled underground moist place until the puddle water, and then out activities.
