Flatworms
The phylum Platyhelminthes (aka flatworms) are rather primitive invertebrates that can be either parasitic or non-parasitic depending upon the species. They have no body cavity, no circulatory organs and no respiratory organs. Questions about flatworms can be asked and answered here.

Is heartworm caused by flatworms?
No, a heartworm is worm that slowly...eats(one way to put it) the heart of any animal or human. a roundworm doesnt really cause much harm. Its a worm that takes the shape of a circle undera small bit of skin. its visual
What are 5 examples of a flatworm?
Flatworms - classified as having a flat leaf or flat ribbon shaped body and a pair of eyes up front. Most are parasitic.
Examples of the flatworm include Tricladida, flukes, and tapeworms.
Roundworms (aka nematodes) - has over 80,000 species which many of are parasitic. They have round bodies of varied sizes.
Examples of the roundworm include whipworms, hookworms, and pinworms.
Segmented Worms - As their name describes, their bodies are divided into segments.
Examples of the segmented worm include the bristle worm and earthworms.
No flatworms do NOT have nostrils they have eyes and the ability to regenerate damaged parts of their body but no nostrils.
No, flatworms are from the phylum Platyhelminthes, while worms are from the phylum Annelidia. Worms are more developed and have a coelum, while flatworms have no coelum at all.
What do flatworms roundworms and segment worms have in common?
flatworms arent round but flatworms look like pancakes. they both belong to the invertabre group and have similar internal organs.
What are the medical importance of flatworms?
Flatworms are important to nature as they can be an indicator of changes in the habitat because they are sensitive to water and indicate reduced oxygen, among other things. They are also important because the ecosystem is based on all living creatures and the flatworms eat the tiny plans and animals that go unseen and then when they are eaten by fish or aquatic insects the base of the food chains that the flatworms ate then become part of the larger ecosystem food chain.
Compare and contrast the body of a flatworm to the body plan of a roundworm?
Flatworms are considered acoelomate, since they have no body cavity, and roundworms are pseudocoelomate because they have a body cavity, but it is not derived from the splitting of the mesoderm tissue.
Also, flatworms only have one opening in their digestive system unlike roundworms with two.
Yes, flat worms do have true tissues since they posses a mesoderm and are tripoblastic bacause of this.
However, these organisms do not posses a body cavity and no specialized circulatory or respiratory organs.
What does the leopard flatworm eat?
they are consumer or predators and they are parasitic like tapeworms and flukes
What class do flatworms belong to?
They belong to any class that are under the phylum platyhelminthes.
Why does cutting a flatworm into pieces not kill it?
In gereral, the more poorly differentiated (the fewer complex structures that have specific functions) an organism is, the greater its ability to live and re-grow after being cut apart. Worms have this ability to re-grow in entirety, as do lower organisms like amoebas and fungi. In flatworms, their cells have the ability to differentiate into any type of tissue that the worm might need. These types of cells are called stem cells, and are the subject of ongoing research in medicine as to their applications in humans. There is a limit, however. a tiny slice of flatworm would not be able to develop into another worm.
How do earthworms play a role in the ecosystem?
earth worms and other members of PHYLUM ANNELIDA are different from other worms in that they are SEGMENTED meaning that internaly, earthworms separated into segments by a thin membrane called the SEPTUM. Earth worms are also known for their barrel shaped CLITELLUM -----------=----

that usulally covers segments 32-37. one more thing... earth worms have a CLOSED circulatory system, while most other worms have OPEN circulatory systems. hope this helps
What does a flatworm have inside its body?
Flatworms and Roundworms have bilateral symmetry as a body type.
Ascarids are not vertebrates; they are of the genus Ascaridae, parasitic nematodes generally thought of as intestinal roundworms. Parascaris equorum, the equine roundworm and probably the most common Ascarid, infects horses, donkeys, and zebras, but is not known to infect humans or other animals. Ascarids are usually species-specific -- Ascaris lumbricoides affects humans and causes the disease ascariasis while Ascaris suum infects pigs, but there is a possibility that these two species may cross-infect humans and pigs.
