Why do fleas jump so far relative to their size?
Quick Answer
Fleas use elastic protein structures in their legs to store and release energy like tiny springs. That allows them to leap distances many times their body length.
The Full Story
Fleas are extraordinary jumpers because their hind legs contain resilin, a very elastic protein that stores energy before a leap. When released, this energy propels them quickly and efficiently. Their small size also helps them achieve impressive relative distances, sometimes many times their body length. Jumping is useful for moving between hosts and escaping danger. The flea’s anatomy is a classic example of biological spring mechanics.
