Flatworms

?

Research has shown that the flatworm communicates via the gap junctional channels. This also applies to the other types of worms as well.

the flat worm gets rid of waste through the same openinig takes in food

They are filter feeders that draw water into their pores, filter out tiny sea invertebrates that are absorbed and digested, and expel the remaining water in a continuous basis.

oh no. they are most definitely parasitic worms. they can get inside a persons body and live off their food supply in the person's intestines. They can grow quite long too, about 27 or more feet.

Commensalism-The flatworm benefits from eating bits of food from what the crab ate. The Horseshoe Crab is unchanged as far as scientists know. Commensalism is a form of symbiosis that benefits one organism without affecting the other organism.

Flat worms do not have blood. There fore, they do not require a respiratory system to infuse fresh oxygen into the blood. This lack of a respiratory system, means they do not have lungs.

It would be difficult to have a parasitic flatworm as a pet as you would also have to have a host for it to survive.

It might be possible to have a free living flatworm as a pet. Feeding them would be difficult. Polyclads have the ability to self-destruct under stress, so, if disturbed and taken from their natural habitat, they would probably die.

Yes that is true

you can eat it and play with it whenever you like. . .

Fluke tester equipment can be purchased at Canadian Tire, Lowe's as well as Home Hardware. One would use this to test wiring or electrical voltage. Prices vary depending on style and model.

They are not economically important to humans. This is because, being aquatic, animal-like organisms, they don't officially belong to any country. Planarian worms come to America, Great Britain, France, China, South Africa, Canada, Russia, etc. looking for jobs. They take jobs illegally, make money that belongs to that country, but don't give anything back because they don't pay taxes. They were the economic downfall of Greece, and if you don't watch out, they'll be your country's downfall, too.

organ system

1)Bilaterally symmetrical.

2)Body having 3 layers of tissues with organs and organelles.

3)Body contains no internal cavity.

4)Possesses a blind gut (i.e. it has a mouth but no anus)

5)Has Protonephridial excretory organs instead of an anus.

6)Has normally a nervous system of longitudinal fibres rather than a net.

7)Generally dorsoventrally flattened.

8)Reproduction mostly sexual as hermaphrodites.

9)Mostly they feed on animals and other smaller life forms.

10)Some species occur in all major habitats, including many as parasites of other animals.

species of schistosomes . Schistosoma mansoni is widespread in Africa, the Eastern-Mediterranean, the Caribbean, and South America and can only infect humans and rodents.

Flatworms have bilateral symmetry. Bilateral symmetry means the animal 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.

Are you asking: "how long does a flatworm live?"

If so, this is not an answerable question--there are too many types of flatworms to make a generalization.

I personally know of one type of flatworm which can re-generate--cut off any part of it's body, and that part will re-generate. As long as the head remains attached, the re-generation can take place.

I did a science project using freshwater planarians, where I explored this phenomenon.
