Arthropods (phylum Arthropoda) are members of a large phylum of animals. The word "arthropoda" means jointed legged, so evidently all arthropods are jointed legged. All arthropods also have exoskeletons made primarily of a hard protein called chitin. Arthropods are grouped into the insects, arachnids, crustaceans, and myriapods. Insects are a class of arthropod with three body segments - the head, the thorax, and the abdomen. Arachnids and crustaceans have the head and thorax combined into one --- this is known as the cephalothorax. However, arachnids do not have antennae, but crustaceans have a set of antennae and another set of shorter antennules. Myriapods are the subphylum with the centipedes and millipedes. Their bodies are divided into A LOT OF SEGMENTS!!!!
The arthropods are almost as biologically diverse as the chordates.

Any of the set of animals that belong to the insect family.
They put flames on my beetle when they pimped my arthropod.
