37. Phylum Arthropoda
Jointed-foot Animals
Nearly one million species identified so far, mostly insects.
The exoskeleton, or cuticle, is composed of protein and chitin.
Circulatory systems
HABITAT and STRUCTURE OF MOUTH
Aquatic members- gills for gas exchange;
terrestrial members- tracheal system of branched tubes leading from
surface throughout body.
