Millipedes and centipedes are closely related to which type of organism?

• A. Insects
• B. Crustaceans
• C. Amphibians
• D. Reptiles

Answer: (B)

Millipedes and centipedes are classified within the phylum Arthropoda, which also includes crustaceans, insects, and arachnids. Specifically, millipedes and centipedes belong to the class Myriapoda. Crustaceans share this phylum, making them a closely related group, as they also possess jointed legs and segmented bodies, key characteristics of arthropods. Insects, while part of the same phylum, belong to a different class. Amphibians and reptiles, on the other hand, belong to the phylum Chordata, which is entirely separate from the arthropods. Hence, the relationship of millipedes and centipedes to crustaceans is due to their shared classification within the broader category of arthropods, making crustaceans the most closely related type of organism in this context.
