An organism or creature that lacks clearly defined or distinct feet or legs.
From Greek 'a-' (without), 'delos' (clear), and 'pous' (foot). Used in zoology to describe animals whose limbs are obscure or poorly developed.
Worm-like creatures can be adelopods because their bodies blend limbs and body segments together so much that it's hard to tell where a foot even is!
