Summary Introduction
To list: The four extant classes of arthropods and a characteristic that distinguishes them from one another.
Introduction: The members of arthropods are small, usually a few millimetres in length, and the adults range in size from about 80 micrometer long. These organisms consist of segmented body, exoskeleton, and joined appendages. The segments are specialized into
