Here are some characteristics of flatworms:
parasites
digestive system
they live on their host's
tape worms
There are three different groups of animals known as "worms": flatworms (phylum: Platyhelminthes), roundworms (phylum: nematoda), and segmented worms (phylum: annelida).
No. there are three kinds of worms: platyhelminthes- flatworms(not) nemahelminthes-roundworms(not) annelids-segmented worms( segmented)
Flatworms and Roundworms have bilateral symmetry as a body type.
there are three
Turbellaria , Trematoda and cestoda
Pig worms, hookworms, and Vinegar eel worms
Hookworms 2) Pinworms 3) Leonia Worms.
The three characteristic are temperature, size, and brightness.
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.
biologist classify worms into three major phyla-flatworms roundworms and segmented wormsYes, that is true, but those are not characteristics! Some of their characteristics are:-A knot of nerve tissue-Sense organs-Sexual reproduction-Bilateral symmetry-Obtaining food by sucking their hostsGood luck!!!! I know science can be challenging at times!!!!!! :D
There are three types of worm parasites common to felines. Roundworms, tapeworms and hookworms. There are also microscopic parasites. For more info go to this site. http://www.vetinfo.com/signs-feline-worms.html
Worms (excepting the flatworms) are the simplest animals to have a one-way digestive tract (that is, they do not expel waste from the same hole that they eat through). Originally, the animals for whom it is taxonomically correct to call worms were all classified under the single phylum Vermes; later, they were split into three separate phyla: Platyhelminthes (planarians, or flatworms, this being the simplest of the three worm phyla) Nematoda (nematodes, or roundworms) and Annelida(annelids, or segmented worms such as earthworms and leeches; this is the most physiologically complex of the three worm phyla); over time, several new phyla have been developed.Worms are so separately classified partially because their eating habits and oral anatomy are so diverse. Many, such as earthworms, are decomposers (dirt and debris eaters); earthworms suck food into their bodies and push it down along the body using peristaltic muscular contractions. Other worms, such as leeches and many varieties or roundworm and flatworm, are parasitic. Some species of leeches can bite humans, latching on with their suckers and secreting anticoagulant to keep the blood flowing into the gullet. Roundworms have a digestive system lined with hard cuticle and often ridges; some species (the carnivorous ones) have teeth; others have a stylet that they can poke into other organisms to suck fluids out.Unlike roundworms and annelids, flatworms do not have a mouth; they absorb nutrients through their skin. However, flatworms are the simplest animals to have a specialized digestive and excretory system.
