Annelids are classified based on several key characteristics, including their segmented body structure, which features repeated units called segments. They possess a true coelom, a closed circulatory system, and a complete digestive tract. Additionally, annelids exhibit various types of locomotory structures, such as setae (bristle-like structures) and parapodia (fleshy outgrowths), which aid in movement and burrowing. Their classification also considers reproductive methods, with some being hermaphroditic and others exhibiting distinct male and female forms.
