Which Animal Jumps Highest Relative to Its Size?

The flea. Relative to its body size, the flea is the highest jumper in the animal kingdom, leaping up to 100 times its own height.

A flea can jump roughly 18 cm high and about 33 cm across, which is around 100 to 150 times its own body length, far more than any larger animal can manage proportionally.

Fleas store energy in a stretchy protein called resilin and release it like a spring, giving them explosive acceleration that beats bigger animals when measured relative to body size.
