Arthropoda is a phylum of animals that includes many well-known invertebrates such as insects, crustaceans, spiders, centipedes, millipedes and scorpions. The distinguishing features of arthropods from other invertebrates are their hard exoskeleton or shell and jointed limbs.

Which group of arthropods has the most species?

What kind of exoskeleton does an arthropod have?

Arthropods is a phylum that includes insects and spiders. They are invertebrates, which means they do not have an internal skeleton and backbone.

Why do arthropods live on the outside of the body?

Many of them have “knee” joints very similar to ours, he says. Our hard parts — bones — are on the inside, beneath our skin. Arthropods instead put their tough stuff on the outside where it acts as a suit of armor, Edgecombe says. This lets them live in rough environments, including underwater and underground.
