How Does a Flea Travel So Fast?

The answer to the question, “How does a flea travel so fast?” involves examining the speed of the flea. Despite its low weight of 0.45xkg, this insect can jump at 0.74m/s. The flea is powered by a muscle that can generate 60W/kg of force. It also has a resilin pad at the base of its hind leg, which compresses when the flea bends its leg to jump. The pad measures 6.0xm in length and stores energy when fully compressed.
