arthropoda

n. family of animals with jointed legs and hard segmented bodies (includes crustaceans, spiders and insects)

Arthropods (Phylum Arthropoda, from Greek , "joint", and , "foot") are the largest phylum of animals and include the insects, arachnids, crustaceans, and others. Arthropods are characterised by the possession of a segmented body with appendages on each segment. They have a dorsal heart and a ventral nervous system. All arthropods are covered by a hard exoskeleton made of chitin, a polysaccharide, which provides physical protection and resistance to desiccation. Periodically, an arthropod sheds this covering when it moults.
