Organ-system level of body organization.
Body bilaterally symmetrical, triploblastic and metamerically segmented.
Appendages jointed, usually one pair to a somite, and with varied functions as jaws, gills, legs, etc.
True coelom reduced and largely replaced by a blood-filled haemocoel.
Muscles mostly striated, usually capable of rapid constriction.
The exoskeleton of dead chitinous cuticle that is shed at intervals, called ecdysis or moulting, for growth and development.
Body division into the head, thorax, and abdomen. Head and thorax often fused to form a cephalothorax.
