the tiny soil-dweller that built a slingshot into its own butt
means A minute wingless arthropod (order Collembola) found in soil and leaf litter, named for the forked, tail-like appendage it snaps against the ground to spring through the air.
from A plain English compound of "spring" (to leap) and "tail," describing the creature's escape mechanism: the furcula, a forked organ folded beneath the abdomen and released like a catch. The scientific name Collembola comes from Greek kolla "glue" and embolos "peg," referring to a separate tube-like organ (the collophore) once thought to be a sticky anchor.
