Talk:Crinoid

Untitled
This web page http://www.jeffssite.net/Fart%20facks.htm states: "The crinoid is a marine creature with a U-shaped gut, and its anus is located next to its mouth." It doesn't look like the article on Crinoids mentions this interesting piece of information. Should it?

Just added further information to this article. The new text needs links added to other articles.

Some of the text added to the article was originally published by me on the Web back in 1998.

The fossil history is fascinating but I was looking for information on the biology and ecology of feather-stars. Will there be an article on this elsewhere? I was particularly interested to discover if featherstars are considered an indicator species. I noticed a very significant decline in the number of these creatures around one of the resort islands in Fiji between 1987 and 2005. --Mylesclough 07:35, 10 October 2005 (UTC)


 * You might try echinoderm and see if there is anything there. This article does need a bit of updating/improving. --DanielCD 15:59, 11 October 2005 (UTC)

I updated this page with just some simple nicknames for the small fossilized segments. I believe it to be a mostly regional thing, but if someone is familiar with their monikers in another part of the country, that'd be great.

Sorry, last comment was me. Terminall 16:05, 21 January 2006 (UTC)

I don't know how to comment, But I see that there si no part in the article mentioning their reproductive cycle, seems like they would have one, but I cannot find it here -lee 2:25 3 April 2007 (CT)

Cladida, Flexibilia, Camerata and Disparida have links to pages that don't exist. Does somebody know how to fix those links?

Aaglacrinus
I just made a genus page Aaglacrinus but I am concerned that it might be similar to the more common (according to google hits only) Aglaocrinus. I noted the species in the genus page down as Aaglaocrinus (as my sources provided) but I thought an expert was needed to check up on whether they are the same or different. In the big list of crinoids, Aaglacrinus and Aglaocrinus are listed separately, while Aaglaocrinus is not listed at all. My guess is Aaglacrinus and Aaglaocrinus are the same while Aglaocrinus is different but as I said; any expert to look at this would be appreciated. Kind regardsCalaka (talk) 09:49, 24 March 2010 (UTC)
 * Ah I figured it out, all good! Unless anyone wants to create it first, I will make the genus from the other extinct crinoid sometime tomorrow. Cheers!Calaka (talk) 10:08, 24 March 2010 (UTC)

"typical" crinoid fossil
It is funny to me that someone would label File:Fossile-seelilie.jpg as "typical," when "exquisitely preserved" would be nearer the mark. Most of the time all you see are columnal fragments - that is "typical" in a crinoid fossil.Jstuby (talk) 21:29, 4 January 2011 (UTC)
 * I've changed the wording so that "typical" modifies "crinoid" rather than "fossil", probably what the original author meant anyway. --Danger (talk) 05:49, 5 January 2011 (UTC)

Crinoidea
Why isn't this article put under the scientific term Crinoidea rather than under the more common term "crinoid". To be sure, any member of the Crinoidea is a crinoid; so what.

I tried moving to Crinoidea, but was unable, apparently due to the term having been (properly) used before J.H.McDonnell (talk) 13:02, 1 September 2011 (UTC)
 * The fact that it is the more common term is probably the reason it's here. I'm not against a move, though, I don't feel qualified to meddle in invertebrate affairs. Abyssal (talk) 18:07, 1 September 2011 (UTC)

Syzygy
Syzygy (disambiguation) links here, but this article fails to explain why. 86.26.14.250 (talk) 23:26, 5 February 2013 (UTC)

Sars
Michael Sars's article claims that his discovery of living stalked crinoids launched the Challenger expedition that launched modern oceanography. If so, should be sourced and mentioned here. — Llywelyn II   15:49, 9 August 2014 (UTC)

contradictn(intro
Those crinoids which, in their adult form, are attached to the sea bottom by a stalk are commonly called sea lilies.[5] The unstalked forms are called feather stars[6] or comatulids.[7]... Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults.81.11.219.200 (talk) 14:54, 1 February 2017 (UTC)

Size inaccuracy?
I am worried that the largest crinoid ever found size (40m) is false information. That would be longer than a blue whale, while in your “largest animals” page you cite that the biggest animal ever is the blue whale. “Biggest” is such a subjective term I know, but I am still worried that this is false info. However, I am not sure enough to make an edit, perhaps someone with more knowledge could help? 165.106.120.238 (talk) 09:43, 24 September 2023 (UTC)

The french page
the french version of Crinoidae has a LOT more data about Crinoidae, could/should we had some to the English version? It would require a Crinoid "expert" to verify the relevance of it all. I'm new to contributing, just wanted to know how we translated "feather star" in french, and.. we don't seemingly! But seeing the difference in size between the 2 I thought maybe I could contribute with translating? Thanks for whoever will read Kinonak (talk) 23:51, 5 October 2023 (UTC)
