1. acoelomate - no coelom\n2. pseudocoelomate - unlined coelom which forms form blastocoel\n3. eucoelomate - lined coelom which forms from mesoderm

An amoeba is the smallest animal in the world. It is a single cell organism. This means it has ONLY one cell in its whole body and insides.

The gastrointestinal tract or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.\n\nThe GI tract differs substantially from animal to animal. For instance, some animals have multi-chambered stomachs.

its a member of the kingdom Protista, which includes eukaryotic, mostly unicellular organisms with animal-like (protozoa), plantlike (algae), or funguslike (slime moilds) modes of nutrition. I take microbiology in collage if u need more info email at Njacobs7477@yahoo.com

Peyer's patches( Peyer's patches are areas of lymphoid tissue located in the wall of the intestine, and in some mammalian species such as sheep, cattle  and rabbits, Peyer's patches have a function similar to the bursa of fabricius of birds and bone marrow of other mammals: B cell differentiation and maturation.)\n6.Bursa of Fabricius 7. GALT (Gut Associated Primary Lymphoid Tissue ) 8. MALT ( mucosa-associated lymphoid tissue)

Many organisms possess vestigial structures that have no apparent function, but that resemble structures their presumed ancestors had. Humans, for example, possess a complete set of muscles for wiggling their ears, just as a coyote does (table 22.1). \n\nBoa constrictors have hip bones and rudimentary hind legs. Manatees (a type of aquatic mammal often referred to as "sea cows") have fingernails on their fins (which evolved from legs). Figure 22.17 illustrates the skeleton of a baleen whale, which contains pelvic bones, as other mammal skeletons do, even though such bones serve no known function in the whale. The human vermiform appendix is apparently vestigial; it represents the degenerate terminal part of the cecum, the blind pouch or sac in which the large intestine begins. In other mammals such as mice, the cecum is the largest part of the large intestine and functions in storageusually of bulk cellulose in herbivores. Although some suggestions have been made, it is difficult to assign any current function to the vermiform appendix. In many respects, it is a dangerous organ: quite often it becomes infected, leading to an inflammation called appendicitis; without surgical removal, the appendix may burst, allowing the contents of the gut to come in contact with the lining of the body cavity, a potentially fatal event.\n    \nThe skeleton of a baleen whale, a representative of the group of mammals that contains the largest living species, contains pelvic bones. These bones resemble those of other mammals, but are only weakly developed in the whale and have no apparent function.\n    \nIt is difficult to understand vestigial structures such as these as anything other than evolutionary relicts, holdovers from the evolutionary past. They argue strongly for the common ancestry of the members of the groups that share them, regardless of how different they have subsequently become. \nComparisons of the anatomy of different living animals often reveal evidence of shared ancestry. In some instances, the same organ has evolved to carry out different functions, in others, an organ loses its function altogether. Sometimes, different organs evolve in similar ways when exposed to the same selective pressures.

http://en.wikipedia.org/wiki/Parelaphostrongylus_tenuis\n\nMorphology\n\nRoundworms are triploblastic protostomes with a complete digestive system. Roundworms have no circulatory or respiratory systems so they use diffusion to breathe and for circulation of substances around their body. They are thin and are round in cross section, though they are actually bilaterally symmetric. Nematodes are one of the simplest animal groups to have a complete digestive system, with a separate orifice for food intake and waste excretion, a pattern followed by all subsequent, more complex animals. The body cavity is a pseudocoel (persistent blastula), which lacks the muscles of coelomate animals used to force food down the digestive tract. Nematodes thus depend on internal/external pressures and body movement to move food through their digestive tracts. The mouth is often surrounded by various flaps or projections used in feeding and sensation. The portion of the body past the anus or cloaca is called the "tail." The epidermis secretes a layered cuticle made of keratin that protects the body from drying out, from digestive juices, or from other harsh environments, as well as in some forms sporting projections such as cilia that aid in locomotion. Although this cuticle allows movement and shape changes via a hydrostatic skeletal system, it is very inelastic so does not allow the volume of the worm to increase. Therefore, as the worm grows, it has to moult and form new cuticles. The cuticles don't allow volume to increase so as to keep hydrostatic pressure inside the organism very high. For this reason, the roundworms do not possess circular muscles (just longitudinal ones) as they're not required. This hydrostatic pressure is the reason the roundworms are round.\nMost free-living nematodes are microscopic, though a few parasitic forms can grow to several meters in length. There are no circular muscles, so the body can only undulate from side to side. Contact with solid objects is necessary for locomotion; its thrashing motions vary from mostly to completely ineffective at swimming.\nRoundworms generally eat bacteria, algae, fungi and protozoans, although some are filter feeders. Excretion is through a separate excretory pore.\nReproduction is usually sexual. Males are usually smaller than females (often very much smaller) and often have a characteristically bent tail for holding the female for copulation. During copulation, one or more chitinized spicules move out of the cloaca and are inserted into genital pore of the female. Amoeboid sperm crawl along the spicule into the female worm.\nEggs may be embryonated or unembryonated when passed by the female, meaning that their fertilized eggs may not yet be developed. In free-living roundworms, the eggs hatch into larva, which eventually grow into adults; in parasitic roundworms, the life cycle is often much more complicated.\nRoundworms have a simple nervous system, with a main nerve cord running along the ventral side. Sensory structures at the anterior end are called amphids, while sensory structures at the posterior end are called phasmids.\n\nhttp://en.wikipedia.org/wiki/Nematode\n\n\nHope that helps!

I'm not a dentiation expert, but I associate cecum size with diet.  Herbivores have very large cecums and carnovores have smaller ones.  I associate hypsodont molars with horses and such, so I'm going to say they have the larger cecum.

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.
