How do fleas jump so far for such tiny insects?
Quick Answer
Fleas use a spring-like protein called resilin to store energy before jumping. When released, that energy launches them many times their body length.
The Full Story
Fleas have powerful hind legs and specialized elastic structures that help them store and release energy very quickly. The protein resilin acts like a biological spring, making their jumps explosive rather than slow and muscular. This allows fleas to jump far relative to their size, which helps them move between hosts and escape danger. Their jumping ability is one reason they were so successful as parasitic insects.
