A flea can jump 60 times its length in height and 110 times its length in distance, equivalent to a 1.8 m (6 ft) adult human jumping 110 m (361 ft) vertically and 200 m (656 ft) horizontally. Rarely do fleas jump from dog to dog. Most flea infestations come from newly developed fleas from the pet's environment. [6]
The fleas usually undergo metamorphosis and overwinter as pre-emergent adults. These are fully formed within the cocoon and emerge when certain stimuli occur; suitable stimuli are vibration, heat, or increased levels of carbon dioxide. [9] These fleas generally come into contact with their host by jumping.

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
This includes flea-borne tapeworms, which can infect pets and rarely humans, and occurs if the flea is ingested. It may cause stomach ache, loss of appetite, stool changes, gas, weight loss ...
The Tex Avery cartoon The Flea Circus (MGM, 1954) features a French flea circus that disbands when the fleas see a dog and attack it; one flea, François (voiced by Bill Thompson, best known as the voice of Droopy), who played a sad flea clown, marries the star flea, Fifi, and they have enough offspring together to bring the flea circus back to life.
Jumping fleas are used for kicking small lightweight balls. They are carefully given a ball; when they try to jump away (which is not possible because of the harness), they shoot the ball instead. Running fleas can pull small carts and vehicles or rotate a Ferris wheel. [5] [full citation needed]
One study looked at several species of flea beetles, including the Altica cirsicola species, and described the jumping mechanism of these beetles to be very efficient. [4] This study even applied the knowledge gained from the flea beetles to create a preliminary design for a bionic leg that can jump. [4] Flea beetles can also walk normally and fly.
The Oriental rat flea (Xenopsylla cheopis), also known as the tropical rat flea or the rat flea, is a parasite of rodents, primarily of the genus Rattus, and is a primary vector for bubonic plague and murine typhus. This occurs when a flea that has fed on an infected rodent bites a human, although this flea can live on any warm blooded mammal ...
