Earthworm (Lumbricus terrestris). The worm's body is split into multiple segments, each of which have four pairs of tiny, almost invisible, bristles. These help the worm grip the soil as it pushes forward underground. A mucous covering helps prevent it drying out as well as lubricating its movement through the soil.
