Flea

A tiny parasite with the greatest vertical leap in nature/Insects & Arachnids

Fleas can jump up to 150 times their own body length, the equivalent of a human leaping over a 45-story building. They achieve this by storing energy in a pad of resilin, a nearly perfect elastic protein, then releasing it all at once to catapult themselves at accelerations exceeding 100 g. Fleas have plagued mammals for at least 50 million years and are so well adapted to their parasitic lifestyle that they are basically impossible to eradicate completely.
