What's the difference between platyhelminthes and nematodes?

Platyhelminthes and Nematoda are two invertebrate animal phyla. Platyhelminthes consists of flatworms whereas Nematoda consists of roundworms. The main difference between Platyhelminthes and Nematoda is the anatomical structure of the body of each invertebrate.

How are the roundworms more advanced than the flatworms?

Bilateral symmetry allows the flatworms to move and to have sensory organs in the front. How are roundworms more advanced than flatworms? ... This allows room for all organs in between the guy and skin. They also have blood vessels.

Where can roundworms be found?

Roundworms can live in or on humans, and can cause many problems. They are usually found in soil and stool and can enter the body through the mouth or direct contact with the skin. They can live in the human intestine for a very long time.

What diseases do flatworms cause?

Paragonimiasis is caused by infection with a flatworm. That's a parasitic worm also called a fluke or lung fluke because it commonly infects the lungs. Usually, infection comes after eating undercooked crab or crayfish that carry immature flukes. Once swallowed by a person, the worms mature and grow inside the body.

Where are nematodes found?

Nematodes are among the most abundant animals on Earth. They occur as parasites in animals and plants or as free-living forms in soil, fresh water, marine environments, and even such unusual places as vinegar, beer malts, and water-filled cracks deep within Earth's crust.

How do flatworms asexually reproduce?

Flatworm Reproduction

Asexually, flatworms procreate via fragmentation and budding. Fragmentation, also called cloning, occurs when a flatworm splits off a part of its body, allowing the separated portion to regenerate into a new worm.

Do nematodes Coelom?

Although nematodes do have a space in the body between the digestive tract and the body wall, it is not lined with tissue and is not considered to be a true coelom. Thus, nematodes are sometimes referred to as pseudocoelomates (Fig. 3.17 C).

Which diseases are caused by roundworms?

Ascariasis is an infection of the small intestine caused by Ascaris lumbricoides, which is a species of roundworm. Roundworms are a type of parasitic worm. Infections caused by roundworms are fairly common. Ascariasis is the most common roundworm infection.

Do flatworms have a Coelom?

Why are flatworms so flat?

The lack of a cavity also constrains flatworms to be flat; they must respire by diffusion, and no cell can be too far from the outside, making a flattened shape necessary. ... Flukes, like other parasitic flatworms, have complex life cycles often involving two or more host organisms.
