Arthropoda is an invertebrate phylum that includes insects, arachnids, crustaceans, and myriapods. It is characterized by a segmented body, jointed appendages, and an exoskeleton. Arthropods inhabit a wide range of habitats, from the ocean depths to the highest mountain peaks. Lifespans vary greatly, from a few days to several years. The current population of arthropods is estimated to be over 10 quintillion. Arthropods are easily distinguished by their segmented bodies, jointed appendages, and exoskeletons.
Name Origin: The name Arthropoda comes from the Greek words arthron, meaning joint, and podos, meaning foot. This is because arthropods have jointed appendages, such as legs, that allow them to move.
