Earthworms distinguishing features from members of phylum platyhelminthes and phylum nematoda?

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).

What are the types of animals?
In the Kingdom Animalia, there are nine major phyla:Phylum Porifera (sponges) Phylum Cnidaria (jellyfish) Phylum Platyhelminthes (flatworms) Phylum Nematoda (roundworms)Phylum Annelida (earthworms)Phylum Mollusca (snails)Phylum Echindodermata (starfish)Phylum Arthropoda (lobsters)Phylum Chordata (humans)
What are the 8 eight subgroups of invertibratesgive the characteristic of each groupof invertebrates?
Porifera Coelenterata Platyhelminthes Nematoda Annelida Molluska Anthropeda Echinodermata
Does a earthworm have bilateral symmetry?
Yes. Earthworms have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What is the phyla of a worm?
It depends what type of warm you are referring to. Flatworms belong Platyhelminthes Tubeworms belong to Nematodes and Segmented worms belong to Annelids Centipedes and Millipedes are not worms. They belong to the Arthropod Phylum.
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.

Unlike platyhelminthes and nematoda, they do possess a body cavity (coelom).
What invertebrate group does the eathworm belong in?
Earthworms belong to the phylum Annelida (ringworms). Note that these are not the only kind of worms; two other phyla are Platyhelminthes (flatworms) and Nematoda (roundworms), and they're all very different from each other. For comparison, another phylum-phylum difference is that between either of the worms and Chordata, being all vertebrates!
Did animals evolve from protists?
Annelida, Arthropoda, mollusa, Nematoda, platyhelminthes, Cnidaria porifera
What are two most common phyla of animals?
The two most common phyla of animals are Arthropoda, which includes insects, spiders, and crustaceans, and Chordata, which includes vertebrates like mammals, birds, reptiles, amphibians, and fish.
Identify the six phylums?
cnidarine, arthropods, sponge, mollusk, worms,lichen
How are worms classified?
There are three different groups of animals known as "worms": flatworms (phylum: Platyhelminthes), roundworms (phylum: nematoda), and segmented worms (phylum: annelida).
