arthropod
Exoskeleton-wearing invertebrate
An arthropod is an invertebrate animal with a segmented body, jointed limbs, and an external skeleton.
The group includes insects, spiders, crustaceans, and centipedes—by far the largest category of animal life on Earth.
The museum's arthropod collection featured beetles, scorpions, and lobsters.
