A parasitic worm is a worm that feeds on another organism, its 'host'. For example a tape worm. It latches onto the intestine of humans.
An arthropod is an organism characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. Examples include spiders, millipedes, lobsters, crabs.

Yes, arthropods are organisms, like all other living things.
A snail would not be classified as an arthropod; it is a mollusk. A starfish, on the other hand, is classified as an echinoderm, not an arthropod either. Arthropods include organisms like insects, arachnids, and crustaceans, characterized by their exoskeletons and segmented bodies. Therefore, neither the starfish nor the snail is an arthropod.
I believe a worm can.
