Which group of arthropods has multiple body segments and pairs of legs?

Myriapods are indeed characterized by having multiple body segments, each of which typically bears one or more pairs of legs. This group includes organisms such as centipedes and millipedes. In myriapods, the segmentation of the body allows for a flexible and elongated form, which is well-suited for their terrestrial habitats.

Insects, while having a segmented body, typically have three major body regions (head, thorax, and abdomen) and possess six legs total. Arachnids, such as spiders and scorpions, usually have two main body segments and eight legs. Crustaceans, which include animals like crabs and lobsters, often have a different body structure and can have multiple legs, but they do not typically exhibit the multiple body segments in the same way myriapods do. Therefore, myriapods stand out as the correct answer in relation to the specific characteristic of having multiple body segments along with pairs of legs.
