Concept:Arthropods are invertebrates with jointed limbs and a hard external covering.
Explanation:A key feature of the phylum Arthropoda is a segmented body.
This segmentation is visible in insects, spiders, and crustaceans.
Arthropods show bilateral symmetry, not radial symmetry.
They possess an open circulatory system, not a closed one.
