Profile springtail (Orchesella cincta) with a size of around 2 mm, made with magnification factor 10 and f/6.4. Members of Collembola are normally less than 6 mm long. Most species have an abdominal, tail-like appendage, the furcula, that is folded beneath the body to be used for jumping when the animal is threatened. It is held under tension by a small structure called the retinaculum and when released, snaps against the substrate, flinging the springtail into the air. All of this takes place in as little as 18 milliseconds (ref. Wikipedia).
