paramecium paramecium. paramecium (parəmēˈsĭəm) [ key ], unicellular organism of the genus Paramecium, of the ciliate phylum Ciliophora found in freshwater throughout the world.Like other protozoans, paramecia, previously considered one-celled animals, are now customarily placed in kingdom Protista.aramecia and other ciliates are the most complex of all single-celled organisms. The paramecium has an external oral groove lined with cilia and leading to a mouth pore and gullet; food (typically smaller organisms, such as bacteria) is digested in food vacuoles.

Clinical Vignettes - Colon Other types of polyps can also be found in the colon, but are far less common and will not be discussed here. Hyperplastic — Hyperplastic polyps are usually small, located in the end-portion of the colon (the rectum and sigmoid colon), have no potential to become malignant, and are of no clinical significance.

- Volvox (Protists). Straddling the plant and animal kingdoms, the protist Volvox forms stunning bright green colonial balls in water bodies that are enriched in nitrates. Found in puddles, ditches, shallow ponds and bogs, Volvox colonies reach up to 50,000 cells and may include daughter and granddaughter colonies.

General Biology/Print version Cnidaria. Cnidaria is a phylum containing over 9,000 species found only in aquatic and mostly marine environments. All cnidarians have radial symmetrical. There are two major body forms among the Cnidaria-the polyp and the medusa.Sea anemones and corals have the polyp form, while jellyfish are typical medusae.When you look at them, you can see that these body forms are the same except that one is upside down.ll cnidarians have radial symmetrical.

protists Xenophyophores are one-celled, multinucleate creatures found at depths of 800 to 6000 meters on the ocean floor. A characteristic feature of xenophyophores is that they construct a sort of artificial exoskeleton by gluing together particles of sediment and the microscopic shells of foraminifera.

- Most bowel polyps develop in the part of the colon called the descending colon. The diagram shows a common site for a polyp to develop but they can occur anywhere in the colon or rectum. The colon and back passage (rectum) are parts of the gut (gastrointestinal tract). The gut starts at the mouth and ends at the anus.

Annelida The oligochaetes live underground in moist soil and only come to the surface if there is heavy rainfall. The Hirundines live near fresh water because they cannot store water well. The polychaetes live in the ocean where they filter feed for food. The roles of annelids are to mate and gather food. Leeches, which are hirundines, prey on any visitors that come near their habitat. In this way, they are parasites to any visitors that enter their environment.

Annelids Mollusks and worms Oligochaetes: (earthworms) live in dirt and fresh water they have very few setae. they are strem-lined body. Leeches: external, parasitic annelids. Razor sharp teeth and suckers to attach to their hosts. they use pharnyx o suck blood. Polychaetes: marine annelids with paired appendages tipped with setae. You find them in coral reefs, sand, rocks, mud, etc.

Polychaete The Polychaeta or polychaetes are a paraphyletic class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin.Indeed, polychaetes are sometimes referred to as bristle worms.ommon representatives include the lugworm (Arenicola marina) and the sandworm or clam worm Alitta. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extreme high temperatures near hydrothermal vents.
