Arthropoda

Phylum Arthropoda

Arthropods belong to the phylum Arthropoda, which means “jointed feet,” and includes four living subphyla. These are chelicerates, including spiders, mites, scorpions and related organisms; myriapods, comprising centipedes and millipedes and their relatives, who are hexapods, including insects and three small orders of insect-like animals; and crustaceans, including lobsters, crabs, barnacles, crayfish, and shrimp.

Arthropods are characterized by the possession of a segmented body with appendages on at least one segment. Arthropod appendages are used for feeding, sensory reception, defense, and locomotion. Their heart is on the dorsal side and the nervous system on the ventral. They are covered by a hard exoskeleton made of chitin, which provides physical protection and among terrestrial species resistance to drying out. In order to grow, arthropods shed their covering in a process called molting.
