Phylum Annelida- characteristics, classification, examples Classification of Phylum Annelida About 8,700 known species of Annelida are divided into four main classes, primarily on the basis of presence and absence of parapodia, setae, metameres, and other morphological features

Phylum Annelida | Biology for Majors II - Lumen Learning Approximately 16,500 species have been described in phylum Annelida The phylum includes earthworms, polychaete worms, and leeches Annelids show protostomic development in embryonic stages and are often called “segmented worms” due to their key characteristic of metamerism , or true segmentation
