Mollusks compose of the large phylum of invertebrate animals known as the Mollusca. Mollusks have a mantle, mollusks invertebrate. Arthropods have jointed appendages, arthropods have segmented bodies
The presence of segmented bodies with jointed appendages is the characteristic that most distinguishes arthropods from other invertebrates. This feature allows arthropods to exhibit a wide range of movement and adaptability in their environments.
Arthropods have an exoskeleton. Mollusks don't.
a scorpion is a Arthropods
Vertebrates have spinal cords. Mollusks and arthropods do not.
because they have no skeleton.
Arthropods are more closely related to humans than mollusks. Both humans and arthropods belong to the larger group called Ecdysozoa, which is characterized by molting exoskeletons, while mollusks belong to a separate group called Lophotrochozoa. This evolutionary relationship places arthropods and humans closer on the tree of life.
Sponges, Cnidarians, Mollusks, and Echinoderms are not Arthropods.
The key similarity between insects and spiders that distinguishes them from other arthropods is that they both have segmented bodies and jointed legs.

Flatworms, Roundworms, Annelids, Mollusks, and Arthropods
Not all animals with antennae are arthropods, although antennae are a characteristic feature of this group. Antennae are sensory structures found in various animal phyla, including some mollusks and certain annelids. However, the presence of antennae is most commonly associated with arthropods, such as insects, crustaceans, and arachnids. Thus, while many animals with antennae are indeed arthropods, they are not exclusively so.
