Worms are soft-bodied, legless animals found in many habitats, though earthworms are especially familiar for their role in soil. They burrow through moist ground, helping break down organic matter and mix the soil; their bodies contract and extend to move, and tiny bristles help many earthworms grip the soil. "Worm" is a broad everyday term rather than one scientific group, so wormlike animals can differ greatly in body structure and habitat. This collection centers on earthworm subjects and also includes worm-shaped plastic fishing bait, which imitates prey for anglers rather than depicting a living animal. Individual worms and grouped subjects reflect these different ways worms appear-as animals and as familiar bait.
