In which arthropod class do sow bugs belong?

Sow bugs belong to the class Crustaceans, which is the correct answer. Crustaceans are characterized by having a hard exoskeleton, jointed legs, and a segmented body, with many members including crabs, lobsters, and shrimp. Sow bugs, specifically known as pill bugs or woodlice, are terrestrial crustaceans that are often found in moist environments. They exhibit distinct features such as two pairs of antennae and a body divided into a head, thorax, and abdomen.

While Diplopods and Chilopods consist of millipedes and centipedes, respectively, these groups are not related to sow bugs; they belong to the class Myriapoda. Arachnids, such as spiders and scorpions, also do not include sow bugs, as they are fundamentally different types of arthropods within the class Arachnida. Thus, the classification of sow bugs as Crustaceans accurately reflects their biological characteristics and evolutionary lineage.
