- Oops, I have a question. The page in question, http://www.palaeos.com/Invertebrates/Echinoderms/Echinoidea/Echinoidea.htm , says "page by M. Alan Kazlev. Are you M. Alan Kazlev? Also, it says "this material may be freely used for non-commercial purposes" which is NOT the same as saying it is released under the GPL. For the record, I think you should add a note here explaining the connection between your work and M. Alan Kazlev, and stating specifically that you are "releasing the material under the terms of the Wikipedia license." Sorry to be a nuisance. I guess the theoretical question is that it is conceivable that you gave your material to the www.palaeos.com website and that it is no longer yours to give to Wikipedia. In such a case, probably the Right Thing to do would be to get the www.palaeos.com to give you a formal statement saying that it OK to use Paleos material in Wikipedia, which they might be happy enough to do.

Hi, Sorry I'm not quite sure I understand. I'm not M. Alan Kazlev, and the original article I submitted to the Web back in 1998 was written by me. It was published on my now defunct site www.fossil-company.com (The Fossil Company). I can supply you with a link to an archived version of the site if you wish. (By the way, the picture of Lovenia woodsi in the article on the site M. Alan Kazlev was copied from my 'The Fossil Company' site, as was some of the text....).

Here is a link to an archive of my original article from Apr 28, 1999:
http://web.archive.org/web/19990420022446/www.fossil-company.com/about_fossils/echinoids.html
I'd say Alan Kazlev "borrowed" from it extensively:

Here is my copyright statemant from the bottom of the original Echinoid article:

Both businesses are now defunct and were owned by me.

OK, it's clear you own the copyright. In a sense when you contribute your material to Wikipedia you are implicitly releasing it under the GFDL because of the notice on the bottom of the edit page, but I think it would be a good idea for you to explicitly say so here. Read Wikipedia:copyright#Contributors' rights and obligations. Then just put something here saying, in so many words, that you are "licensing this material under the terms of the Wikipedia copyright." Probably not necessary, but better to be sure. If you make more contributions of this material, and I hope you will, you may want to make up a little stock sentence saying something like "Copyright © 1995-1997 The Fossil Company Ltd. © 1997-1999 The British Fossil Company Inc. and licensed by the owner under the terms of the Wikipedia copyright." I'm not an expert, but I'm pretty that should do it. Dpbsmith 13:41, 28 Jul 2004 (UTC)
Thanks for explaining this :-)
Should I add the copyright information to the Talk page for each article, or the article text itself ??
Dlloyd 00:45, 29 Jul 2004 (UTC)
It should go on the talk page (here), not in the article itself. Articles themselves do not have by-lines or similar notices, because once it is contributed it can be freely edited—nobody has any "ownership" of the text and any statements about its origin would become outdated the first time someone edited it. Information about the article goes on the Talk page for the article. Dpbsmith 01:07, 29 Jul 2004 (UTC)

[edit] Request for User:UtherSRG to explain the recent deletion
I don't understand why you removed a four-paragraph section from Sea urchin.
I don't understand why you removed a four-paragraph section from Sea urchin without giving any reason here on this Talk page.
I don't understand why you removed a four-paragraph section from Sea urchin and flagged it as a minor edit.
Please explain. [[User:Dpbsmith|Dpbsmith (talk)]] 23:29, 19 Aug 2004 (UTC)
- SRG saw that you added this to category Animalia to this page (this is not what we want - see below) and reverted it - but accidentally swept your previous edits.
- Only phylum taxa (or above) should be added to the animal category - below that the phylum should have its own category - here echinoderm category - as a subcategory of the animal category. SOrry for the confusion. Please visit us at Wikipedia_talk:WikiProject Tree of Life for more. Pcb21| Pete 23:51, 19 Aug 2004 (UTC)
OK, what about all the other articles.... Dlloyd 09:13, 21 Aug 2004 (UTC)

[edit] Starfish
please don't use the term 'star fish'. the term 'sea star'/'sea stars' is preferred by invertebrate zoologists. i'd fix the picture caption at the bottom of the article, but it doesn't appear when editing the main body of the article, and it doesn't appear when editing the image linked to the main body (?)
in any event: 'star fish' == archaeic misunderstanding of Astroidea
(never mind, found it, stupid firefox doesn't search the text in child text boxes on a page. probably not a bug, but a feature, but still...)

- Starfish is perfectly acceptable.
- The dictionary gives several meanings, and specifically includes among these meanings "3. Any of various primitive aquatic vertebrates of the class Cyclostomata, lacking jaws and including the lampreys and hagfishes" and "4. Any of various unrelated aquatic animals, such as a jellyfish, cuttlefish, or crayfish."
- The same dictionary gives the main definition under the entry starfish, with "sea star" being only an "also called." The entry for sea star in that dictionary simply refers us to "starfish."
- I maintain that the use of the phrase "sea star" is silly pedantry. You won't find it used anywhere outside of textbooks and classrooms. Among themselves professionals do not say "sea star." They say "asteroid" or "starfish."
- For no particular reason, someone must have decided at some time that the ordinary English word "fish" should be restricted to the vertebrate class Pisces. But that's silly, and it reflects neither common usage nor the dictionary.
- The use of the word "fish" to refer to any aquatic animal has a long and respectable history, as in "shellfish" and "the lobster fishery" and so forth. Herman Melville defined a whale as "a spouting fish with a horizontal tale." Dpbsmith (talk) 13:45, 14 July 2005 (UTC)

- wait, i'm relatively new to wikipedia, so i want to be a good wikizen, but this seems wrong to me. the *dictionary* trumps people with PhDs in the field and who have devoted their lives to studying the organisms in question? who's being the pedant here?

- Well, I happen to be a Ph. D. in zoology, though not currently active in the field. But I am sure there are other Ph. D's who agree with you. Perhaps you should quote a publication in which one of them expresses an opinion on this matter and gives a good rationale for it. Dpbsmith (talk) 19:37, 14 July 2005 (UTC)

[edit] Monterey Bay urchin population
As a student studying invertebrates at the Long Marine Lab on Monterey Bay with Professor Allison Gong (who studies urchins professionally) I must take issue with the whole urchin population explosion/algae crash portion of the article. what're your sources? we're seeing an *urchin* population crash due to an otter population increase. if this section can't be substatiated, i suggest removing it.
the reason remarks like this chap the hides of invertebrate zoologists is that people are always ready to believe the best of charismatic, celebrity species like Enhydra lutris, but poor old Strongloycentrotus purpuratus gets the short end of the stick every time.
If urchins had frickin' fur and big saucer eyes you guys wouldn't get away with this crap... nauseating. really.
curtains 00:33, 15 July 2005 (UTC)
- Hey, ease up. Just remove it. The polite thing to do would be to remove it from the article BUT paste it here on the talk page with a note saying that you removed it because a) you think it's inaccurate and b) no source is cited. (See Wikipedia:Cite your sources). If you wanted to be really punctilious you might check the article history and contact whomever put that paragraph in (it wasn't me) and see what they have to say about it. Dpbsmith (talk) 19:45, 14 July 2005 (UTC)
- P. S. You might consider creating an account. It takes only seconds, you don't need to reveal so much as an email address, and you get to choose a user name. Dpbsmith (talk) 19:57, 14 July 2005 (UTC)
Actually that was humorous sarcasm (sarcastic humor?). I actually don't care that much, but the tone doesn't come through well in text. My fault. It is just strange to me to see something contrafactual asserted with so much authority in the main body of the text with no sources. I guess that's the rub in the wikipedia.
curtains 00:33, 15 July 2005 (UTC)
- Most encyclopedias, unfortunately, don't cite sources, either. (That's one reason encyclopedias are never cited as authorities in scientific literature).
- But with Wikipedia, when you see something wrong, you can fix it. So... go ahead and fix it. Wikipedia:Be bold.
- By the way... if you look at the Columbia Encyclopedia you'll notice it "asserts with authority" that Jack London "committed suicide at the age of 40." That is extremely debatable and most contemporary scholars do not believe it. Unfortunately, the Columbia Encyclopedia does not have any "edit this page" tab.

- P. S. I've had trouble eating scallops ever since I've seen them looking up at me with their dozens of sweet little blue eyes. Dpbsmith (talk) 02:05, 15 July 2005 (UTC)

[edit] uni caviar?
Which species of sea urchin is most commonly used for "uni" sea urchin caviar?--Sonjaaa 18:47, 9 February 2006 (UTC)
[edit] UNI...
I am a sucker for exotic foods but I must say the most exotic of them all would be the Japanese influenced Uni Sashimi, expensive yet so delectable!
I loved it so much that I went to a local beach and got some edible Urchins over there, got their roes and kept the test for my shell collection!
Their shells are so nice and it really looks different from the other shells that we have. Really unique!
I find them weird though. They look like aliens and a creature from another planet!

What do sea urchins eat?
- They typically scrape algae off the surface on which they are walking. Dpbsmith (talk) 20:35, 12 June 2006 (UTC)
[edit] Echinoidea
Why does Echinoidea redirect to Sea Urchin?
- Because Echinoidea is the scientific name of the class of Echinodermata which corresponds very closely to the group of animals whose common name is "sea urchin," and because the naming convention is to use the most common name as the name of the article itself, and make less common names redirects. Dpbsmith (talk) 20:35, 12 June 2006 (UTC)
[edit] We should not include information on self-treating urchin wounds
Recently added, then removed by another editor:
- One way of removing Sea Urchins that have stuck themselves upon you, is to spray them with Human Urine.
Although this is indeed a folk remedy, I think we should just stay away from this topic. It's much, much too close to offering medical advice.
In Curaçao I was told that urinating on the site of a puncture wound is indeed a folk remedy for sea urchin spine injuries, and I found a published source for this method: a number of travel books by Harry S. Pariser, e.g. [1], which say "take a blunt object to mash up the spine inside the skin so that it will be absorbed naturally. Then dip the wound in urine; the ammonia helps to trigger the process of disintegration."
Bu an emergency medicine text[2] says "External percussion to achieve spine fragmentation is contraindicated" and "Spines within a joint or adjacent to a neurovascular structure should be referred to a surgeon to extract all fragments as soon as possible, and surgical exploration for embedded particles should be delayed until a diagnosis can be made by soft tissue radiography or magnetic resonance imaging (MRI)."
That suggests that in some situations self-treatment by Pariser's method could be a serious mistake.
By the way, there is a scene in Ian Fleming's Thunderball in which James Bond extracts a sea urchin spine from an attractive woman's foot with his teeth.... 12:50, 14 June 2006 (UTC)

The size of the test is stated as 1-4" or 3-10mm, I am assuming that's the diameter?Lucky 23 04:13, 26 October 2006 (UTC)

Removed what was possibly half-hearted vandalism:
Sea urchins are those bloody spiny sea creatures of the class Echinoidea found in oceans all over the world.
was changed to

and
At first glance a sea urchin often appears to be an inanimate object, but its not!!, or one which is incapable of moving.

[edit] Sea Biscuits
Currently the article refers to the article Hardtack from the words "Sea biscuit." This is silly but there is no article for "Sea biscuit (marine animal)." Stenitzer 18:38, 14 January 2007 (UTC)
[edit] Unsourced medical advice
I'm deleting the material below, for these reasons:
- No source is given.
- It amounts to medical advice; if we give medical advice at all, it is absolutely essential to have a solid, unimpeachable, first-rate source.
- When this came up a while ago, I consulted a few books and concluded that the range of advice in books was so wide (and discrepant) that it was really going out on a limb to say anything. Some books made a point of saying that sea urchin spine wounds could potentially be very serious and should always be taken to an emergency room for evaluation... rather alarming since I must have gotten hundreds of them myself and never even thought of seeking treatment for them. Dpbsmith (talk) 01:22, 30 January 2007 (UTC)
[edit] In Case of Contact
So often while swimming in the sea, a person might accidentally step on a sea urchin, the urchin will be on a rock and when stepped on, the urchin will release its spines into the body. This can be sometimes painful (depending on how many spikes went through the skin).
In the case of stepping on an urchin, avoid further pressure on skin surface with the spikes as it will force the spikes deeper and they will be harder to remove. Then to remove them, simply pull the obvious large spikes out and if any spikes are left in the skin, heat some oil (preferably olive oil as it also has an antibiotic effect), and gently immerse the part of skin into the warmed oil (or by using a cotton bud). This will make the skin area around the spike soften and dilate. Then by using a sterile needle force the spike out of the skin and finally pull out by a forceps.
Generally, there is no need for any antibiotic for an urchin spike, however in some cases; doctors might suggest a suitable anti-inflammatory medication.
