跳蚤是昆虫世界里有名的跳高健将。它身长不到5毫米,跳高纪录是22厘米,跳远纪录是33厘米。如果按身高、体长的比例来计算,它算得上是动物世界的跳高冠军了。跳蚤为什么有如此高超的跳跃本领呢?有研究发现,跳蚤的跳跃过程开始于跳蚤将一个关节卡在身体和两条后腿之间。然后它会收缩两块肌肉。这会压缩含有节肢弹性蛋白的一部分身体,从而有效引起一种生物弹力。当跳蚤释放这种弹力时,能量通过其腿部传导 Fleas are the famous jumping high in the insect world. It is less than 5 mm in length, 22 cm in height and 33 cm in long jump. If the height, length ratio to calculate, it is considered the animal world high jump champion.

When fleas release this stretch, energy is transmitted through their legs
