message: I find it odd how long this article went with such blatant vandalism, even with a few edits in the mean time with no-one seeming to notice. I don't normally do any editing though, so maybe this is commonplace.—The preceding unsigned comment was added by 24.146.24.74 (talk) 02:48, 23 December 2006 (UTC)

message: Hello.
While not new to Wikipedia, I've never before attempted to add any content.
Anyways, I have a simple, generic, monochromatic diagram of a paramecium that I created for a Bio class that might fit in well here. However, being new to this system, I have no idea how to upload it and then add it the page, or, more appropriately, add a link to it.

thread_title:  Possible addition 

message: Somebody's put some work into this article recently, but lots of the new material just repeats the (very good) introductory material, only using simpler language. I get the impression that someone pasted in their homework. Unfortunately, their essay started with a verbatim copy of an older version of the article! Nevertheless, the new material does contain some extra information. I've separated it out from the older, better stuff, and cut out some of the more obvious repetition. More work required.

thread_title:  Cleanup Required 

message: This article, while very superficial and in lay terms, was helpful to me. However, there are a couple of points which are confusing and need more detail.
1. "Certain single-celled eukaryotes, such as Paramecium, are examples for exceptions to the universality of the genetic code (translation systems where a few codons differ from the standard ones)." 
   ...?  please explain how paramecium are exceptions to standard dna replication
2."[edit] Symbiosis
One of the most interesting symbiosis relationships known to man is that of Paramecium aurelia and its bacterial endosymbionts. The bacteria infect the protozoa and they produce toxic particles that kill sensitive strains but not killer strains. Giant amoeba, for instance, have 2 types of endosymbiotes, which seem to function as mitochondria in these amoeba. Another example involves protozoa bacteria that produce cellulases that assist the protozoa in cellulose digestion. It is a cell that appears at quiet ponds."
  If the symbiotic relationship between this paramecium and bacteria is  "one of the most interesting known to man,"
it would be nice to know what is known about this relationship. it only says that bacteria infect and kill certain paramecium.  That doesn't sound very beneficial to me. please explain.  also, mentioning the giant amoeba and some unnamed protazoa is out of place here, as it has no direct relationship to paramecium, and belongs in an article about symbiotic relationships. The final sentence looks like it was stuck on at some later point. it should just be deleted.  —Preceding unsigned comment added by Jseagles (talk • contribs) 23:44, 7 October 2007 (UTC)
replies: text: The wording (especially about what "killer strains" actually means) is so ambiguous, I edited it out. If someone puts it back in, they need to clear up just what "killer strains" means does it refer to strains of bacteria or of Paramecium?). rowley (talk) 19:20, 21 June 2010 (UTC)

message: In the Seventh Grade, I had the chance to look under the microscope at some paramecium.
I found it rather surprising when I didn't see any mention of just how fast paramecium can move.
Their little cilla allows them to zip all over the petri dish!
Howver, there may be a lot of types of paramecium, so I may have been looking at just one species.
Yet, they really are fast.

message: Here is a list of the changes I've made:
*Removed specified "brown" color from taxobox (taxobox color for Chromalveolata is automatically green)
*Moved species list from taxobox to the text of the article, to make room for a comprehensive list.
*Removed unreferenced claim concerning new species discovered "in the oceans." (Marine paramecia have been
known for at least 150 years)
*Added a new section on Historical Background
*Created a separate section for Appearance and Physical Characteristics, and brought the description in line with the subject of the page, which is the genus Paramecium, and not any particular species.
* Since some of the information in "Physiology" duplicated passages in earlier paragraphs, I have consolidated these sections, removing redundancies (e.g., contractile vacuoles were described 3 times)
* Removed possibly true but unreferenced claim that paramecia travel at speeds of 12 body lengths per second (not really pertinent here, anyway)
* Corrected the claim that Paramecia have 2 contractile vacuoles (while some well-known species are 
equipped with a pair of cv's, some have only 1, and others have several). 
* Edited passage on osmoregulation for clarity.
* Removed claim that "the cell approximates a prolate spheroid"  Not all species have that shape (although their micronuclei do!).
* Removed true but tangential claim that "Certain single-cell eukaryotes such as Paramecium are examples for exceptions 
to the universality of the genetic code: in their translation systems a few codons differ from the standard ones."
* Removed unsupported claim that Paramecium is often confused with Blepharisma (the genera are not very similar in appearance)
* Rewrote and expanded section on Movement, with citations.
* Provided citations for Feeding section, and edited for stylistic reasons
* Amplified Symbiosis section, removed the colloquial observation that symbiosis of Tetraurelia is "interesting", but kept the citation.  The subject is, indeed, interesting and deserves further elaboration!
* Amplified Reproduction section.  As written previously, the section focused on one species, P. tetraurelia
* Made just one small change to the excellent Aging and Meiosis & rejuvenation sections...replaced "automixis" with the more common,
and specific, term term "autogamy."
* Added a list of valid morphospecies.  This is not a list of all taxonomically accepted names, but of well-described species (based on Fokin et al, 2004)

message: Is the plural of paramecium parameciums or paramecia? I've seen paramecia used in this article, but parameciums used in other places.67.85.219.4 (talk) 17:58, 23 February 2021 (UTC)
replies: text: Both are correct. I did a couple of searches in Google and Google Scholar, and returns indicate that Paramecia is more common, by many orders of magnitude.    Deuterostome  (Talk) 21:15, 23 February 2021 (UTC)
replies: text: I'll add a clarification, in light of Dyanega's helpful edit of Sept. 8. If you are using the scientific name of the genus, the plural form is the same as the singular: Paramecium (italicized, capital "P").  However, informally (in the vernacular, as Dyanega says), the plural form paramecia (lower case, no italics) is commonly used. So, from a major textbook on the genus: "At  the beginning  of the  18th century and extending  into  the  19th, many early microscopists encountered and described ciliates that appear to have been paramecia."
