what are some differences between roundworms and flatworms?
607243
Flatworms and roundworms are as different as frogs and snakes. Or perhaps less different when we forget the science part of it.Flat worms hape a flat body, like tape.And they do not have a coelom. What is a coelom? If you cut open a higher animal (eg. a mouse)you will find that their body is like a hollow bag filled with liquids and organs. The empty space of the body in which these organs lie and which is filled up of body fluids is called coelom. In flat worms, this entire space is filled with compact tissue.Sexes are not separate and specialised cells called flame cells are responsible for excretion. In round worms, the coelom exists but is actually pseudocoelom or "false coelom". This means patches of tissue are present scattered in the coelom. Sexes are separate ie. males and females are separate. Moreover an excretory tube is responsible for excretion instead of flame cells.

red worms and bugs.  check their belly's after you catch them.  they tend to be full of bugs and some worms.  grab a bug that you find while fishing.  the bugs you see around you are the bugs they are eating.

there are 3 basic kinds-epithelial cell shapes and they all vary in their dimensions. Which one are you needing?  Also cell size varies somewhat depending on the organism you find the epithelium in, whether it be one species or several species.\n\nsquamous?\ncuboidal?\ncolumnar?\n\ncolumnar are biggest, squamous are thinnest. Cuboidal are probably the smallest on the average.

Most worms don't realy have a brain. They have nerve ganglia in their heads but they are too simple to be considered brains. The only worms that have what could be considered real brains are the acorn worms.\n\nCan they feel? Well they can sense, which is to say they can move towards food and away form some danger. But cabbages can do that as well. They can't feel in the sense that humans and other mammals can feel. They are not self aware and they can't feel pain, anxiety, joy and so forth

Look up 'nematodes'.\nLook here too:

From an ecological-evolutionary viewpoint, a parasite is a "perfected predator", a predator that has evolved to extract resources from its host without killing it (and for some ecologists, grazing herbivores such as cows and gazelles are also parasites). \nParasites are usually much smaller than their hosts, and their particular characteristics depend on the type of parasite they are. For instance, endoparasites are much more modified and many have lost sensory or even digestive systems in favor of developing larger reproductive organs and producing lots of descendants. Ectoparasites are usually less modified with respect to their free-living relatives, but have structures and behaviors related to finding the host and remaining attached to it. \nObligate parasites are also more specialized than facultative (optional) parasites, and some species are specific parasites of a single host, while others are capable of parasitizing several species. All these different strategies involve diverse modifications, acquisitions and adaptations.\nEventually, parasites may become symbionts, by becoming gradually less damaging to their hosts and more specifically related with them.\nSee the first link for evolution of parasitism:

Technically speaking, it is called the vermiform appendix.  Vermi refers to worm and if you look at an appendix, you will see that it looks quite a bit like a worm.

omg- this is such a complex thing. i just took a parasite class and we talked about nothing but worms and amoebas. worms normally enter through digestion and then burrow their heads between villi. then it grows and matures and deposits eggs through feces. some worms use proglottids, some drop eggs directly into intestines. the eggs are then released out of the anus and ready for another host or vector. some worms end up going though the lamina propria in intestines and getting into hepatic duct and getting into the blood stream. worms can then get into the heart or even encyst in muscle and crippling the muscle if enough get in there. the trichino worm gets into arm muscles and enough render the arm useless.

Think of an ant crawling on a balloon. A big balloon. The ant can't tell that the balloon isn't flat, because he's so small in comparison to it, and the balloon is so large.

There are many types of worms i think it depends on the type...if you say a ringworm well microscopically its pesty carnivore coz it eats you up...but if you say an earthworm well its an omnivore coz it lives down on muddy earth deep in the soil...ok human friend but for more info browse the web human friend!!!oh! more info some poeple eat worms! YUCK!

Porcine Ascarias\n\n \n\n\n\nAscaris suum, commonly known as roundworm, is the largest gastrointestinal parasite of the pig. From a respiratory disease standpoint, roundworms are important because part of their life cycle involves migration of the immature larvae through the lungs of the pig. This larval migration can result in large areas of the lung parenchymal tissue being damaged, with subsequent development of aerobic or anaerobic bacterial infections. As larvae migrate through the lungs, they destroy alveoli; they may cause a local eosinophilic infiltration that sometimes manifests in allergic reactions; and they cause a non-productive cough referred to as "thumps" or "thumping," also known as verminous pneumonia. \n\nBacterial super-infections may also occur, resulting in edema and emphysema, along with a tremendous cellular reaction. Mycoplasmal pneumonia is also not an uncommon sequel to a severe case of ascariasis.

They vary as widely as the body plans of different mollusks, but basically there are both macrophagous (herbivores and predators) and microphagous (suspension feeders) forms.\n \n**Gasteropods (snails and slugs) are mainly herbivorous; they use their radula to scratch plant tissues. However, there are also predatory snails (with modified radula, or proboscis, or even a venom-injecting radula). There are also microphagous planktonic forms (pteropods).\n**Cephalopods (squids, octopi and their relatives) are predatory carnivores, they have a modified radula and a horny "beak" with which they eat different invertebrates and vertebrates.\n**Bivalves (clams, mussels, oysters, etc) are primarily microphagous or suspension (filter) feeders. They don't have a radula and rely on their modified gills for filtration. There are also some primitive detritivores among the bivalvians.\n**The chitons (Polyplacophora) are grazing herbivores (with  radula).\n**The Scaphopoda (tusk shells) capture small food items (particulate matter) with their tentacles (captacula).\n**Other less known mollusks include the caudofoveatans (these capture foraminiferans and other very small organisms from sediments), solenogasters (these eat corals) and monoplacophorans (with a radula, but not much is known about their ecology).

Millions of people are infected by the parasites worms worldwide. Parasites can enter our bodies through food, water, mosquito bites, or through the nose and skin. More than 100 types of parasites worms can be living happily in human bodies. Some are big in size that can be seen by eyes, while the others are microscopic in size. Only about 5 percent of these varieties can be tested positively with only 20 percent accuracy. \n\nParasites worms find a perfectly living environment when the bowel becomes ineffective in the elimination of the waste products due to constipation. \n\nParasites may be categorized into four types: Protozoa, Trematoda, Cestoda, and Nematoda. Nematodes include common roundworm, hookworm, whipworm, pinworm, heart worm, etc.

simple animals have this total regeneration ability, even more, if you cut an earth worm to several pieces, each can regenerate to a complete worm.\nthis is very typical of plants.\nmore advanced/complicated animals have a much smaller regenerative ability. something in the genes of the primitive earth worms is lost among the more advanced animals.

The Annelida have bilateral symmetry .The annelids also have a one-way digestive system . It has a segmented anterior with 8 hearts in each. It also has a body cavity. \n\nThe Mollusks are also bilateral like the annelids. They have a good nervous system. They also have a one-way digestive system. They have a coelom like the . The classes of mollusks are the bivalves, which have two valves, which the name suggests. It has 2 shells and 3 layers also. It has a mantle and it lives in the water. It has gills and abductor muscles. It has an excurrent and incurrent siphon, which no other phylum has. There are the gastropods, which live in land and ocean. It has one shell and one foot. There are also the cephalopods, which has tentacles a foot that can either be a sucker or hook.

If by "red worms" you mean earthworms of the species Eisenia foetida (commonly used for composting), they mostly eat any plant or animal particulate matter that is small enough to enter their mouths; other species (including another common earthworm of genus Lumbricus) can use their sucker-like mouth to ingest relatively large pieces of food. They also ingest live microorganisms along with the detritus. \nEarthworms are part of the soil mesofauna, and usually they don't feed on whole plant parts (such as leaves) but rather on small pieces of particulate matter that have already been generated by other animals of the macro- and mesofauna, especially plant residues (coffee grounds and tea leaves included). They ingest these along with soil inorganic particles (that's why they are important for mixing and carrying organic matter into deeper soil layers).
