Explanation

Arthropods (arthro = jointed, pod = feet) are defined by jointed legs/appendages - a key characteristic of insects, arachnids, crustaceans, etc. Annelids have segmented bodies but unjointed parapodia. Molluscs have muscular feet (not jointed). Platyhelminthes are flatworms without legs.
