Features that distinguish earthworm from phylum platyhelminthes and phylum neinatoda?
Platyhelminthes are bilaterally symmetrical, nonsegmented, dorsoventrally flattened worms characterized by lack of coelom, anus, circulatory and respiratory systems, and exo- or endoskeleton. Nematoda are bilaterally symmetrical and usually tapered at both ends. Some species have separate sexes; others are hermaphroditic.Nematodes have a unique excretory system consisting, in simpler species, of one or two one-celled glands called renette cells and, in more highly specialized forms, of longitudinal excretory ducts. Earthworm (phylum annelid)- The body is annular, made up of segments that are most specialized in the rear. Earthworms have a simple circulatory system. They have two main blood vessels that extend through the length of their body: a ventral blood vessel which leads the blood to the posterior end, and a dorsal blood vessel which leads to the anterior end. Unlike platyhelminthes and nematoda, they do possess a body cavity (coelom).
