1972年夏,中国黄山,桃花溪。两位动物学家正在野外考察。突然,一个又细又尖的“嗞”的声音,穿过其他所有动物的鸣声,钻进他们的耳朵。是岛还是昆虫?循着叫声,两人终于在附近的草丛中找到了声音的来源——一种仅有2,3厘米长的小青蛙。随后的几天,他们共找到19只这种青蛙,而且全是雄性。 Summer 1972, China Huangshan, Peach Creek. Two zoologists are in the field. Suddenly, a thin and pointed “嗞” voice penetrated all the other animals’ sounds and got into their ears. Is the island or the insect? Followed by cry, they finally found the source of the sound in the nearby grass - a small frog only 2,3 cm long. The following few days, they found a total of 19 such frogs, and all male.
