"The only European cave-dwelling chordate" ?

Chordata is the phylum that includes all mammals, amphibians, reptiles, etc. It's very hard to believe that there are no European cave bats, cave bears, etc.

I think that the author responsible for that statement means "the only European cave-dwelling caudate" - the order of salamanders and such. Anybody know what's right here? Peter Delmonte 04:01, 5 September 2007 (UTC)

I second that. Fish are chordates also and there are plenty of cave-dwelling fish. Eregli bob 04:28, 5 September 2007 (UTC)

The statement "the only European cave-dwelling chordate" is correct, if you take "cave-dwelling" to mean "troglobite" (as the link also suggests). Cave bats, cave bears and cave fish are all fine, but they aren't troglobites, since they don't live their entire lives underground. Troglophiles or trogloxenes yes, troglobites, no. This page provides some definitions. And no, there's no troglobite fish in Europe. I reverted the statement accordingly. --Yerpo 12:38, 6 September 2007 (UTC)

It would be nice if someone came up with a citation for this - there's no other mention of it in the article, so it's unreferenced. Allens (talk | contribs) 16:50, 15 March 2012 (UTC)

I can't remember the original reference. Is AmphibiaWeb considered reliable enough? It says "Proteus is the only cave-adapted vertebrate in Europe" under Comments, which is only slightly more specific. — Yerpo 18:54, 15 March 2012 (UTC)

I would think AmphibiaWeb would be considered sufficiently reliable. (Of course, said page also notes that it's possible it actually is multiple species... it'd be greatly preferable for someone to write a review article including that, of course!) At this point, what is needed is the placement of the info (regarding vertebrates) somewhere in the article other than the lead, with the citation. Allens (talk | contribs) 20:04, 15 March 2012 (UTC)

Other than this bare fact, I don't know what more can be said about the issue, so I'm not sure where can we put it without it looking out of place. — Yerpo 20:28, 15 March 2012 (UTC)

Serbian

Is this edit correct? - Face 12:20, 5 September 2007 (UTC)

Orthography is questionable. The correct spelling might be "човечија" or "човечја" - or both. http://sr.wikipedia.org/sr-ec/%D0%A7%D0%BE%D0%B2%D0%B5%D1%87%D1%98%D0%B0_%D1%80%D0%B8%D0%B1%D0%B8%D1%86%D0%B0 —Preceding unsigned comment added by 87.198.255.118 (talk) 20:41, 6 September 2009 (UTC)

The name "olm".

I think the name "olm" should be explained. What is its etymology? The article discusses other names for it but I couldn't find anything on the name "olm". If anyone knows, please include it in the article. Nothingbutmeat 12:56, 5 September 2007 (UTC)

I haven't found anything on the etymology so far, but it might have something to do with the mythological figure of the feathered/plumed serpent in Olmec mythology. That wouldn't have been the first time that olm's gills were mistaken for wings (see Research history. --Yerpo 13:11, 6 September 2007 (UTC)

Cheers! It seems a bit far-fetched, I have to say, though I can't offer a better explanation. Keep looking and I'll see what I can dig up too! Nothingbutmeat 07:03, 7 September 2007 (UTC)

BTW, I didn't mean to imply that the Olmec themselves gave this name to Proteus (that would indeed have been far-fetched, as it doesn't live on that side of the ocean), only maybe some zoologist that got the association. --Yerpo 13:15, 7 September 2007 (UTC)

Ha, ha, no, I got that too! What I meant was, it's odd to think that the name of this animal should have come from a culture on another continent that had nothing to do with it. But as you say, someone may have made that connection. Still, it would be nice to know for sure...Nothingbutmeat 06:25, 10 September 2007 (UTC)

pigmentation consistency

Para. 2: "The olm's eyes have atrophied, leaving it blind, while its other senses, particularly those of smell and hearing, are acute. It also has no skin pigmentation."

Para. 3: "Its body is covered by a thin layer of skin, which contains very little of the pigment riboflavin, making it yellowish-white or pink in color."

Which is it? ericg ✈ 15:11, 5 September 2007 (UTC)

Whatdoe sit eat?

Lol I couldn't find the answer. It looks like a endoparasite but I haven't heard of any such amphibians. So what is it? Carnivore, herbivore...Tourskin 20:42, 5 September 2007 (UTC)

To quote from the article itself, "It is a predatory animal, feeding on small crabs, snails and occasionally insects." bibliomaniac 15 Two years of trouble and general madness 20:43, 5 September 2007 (UTC)

Thanks. Tourskin 20:22, 12 September 2007 (UTC)

Larval characteristics

"This is possibly because of, or perhaps the reason for, their retention of larval characteristics (like external gills) into adulthood." I removed this sentence because there is no reference, but left the information abut its external gills in. "Even breeding" underwater is that unusual in an amphibian? I replaced "atrophied" with "underdeveloped" or "undeveloped" because "atrophy" is used to describe the destruction of an organ by disease, not a vestigial organ. It is used like that sometimes, but it is better like this. The karst links to an article called Karst topography. It is an area of karst topography, but the animals live where the rainfall over the ages has created caves, fissures and similar areas underground. (Amaltheus (talk) 03:09, 24 December 2007 (UTC))

Croatian and serbian name

I don't see the need for the serbian and croatian names to be stated, since the species is, as far as I know, endemic to Slovenia. The names are simply translations and by this logic we could pop a translation in every language into the article. 86.61.40.91 (talk) 14:50, 22 February 2008 (UTC)

The species's habitat area extends from Venice to Bosnia and Herzegovina. Read the article. --Eleassar 10:30, 6 August 2008 (UTC)

Some small changes proposed

I would like to propose some small changes:

Introduction, 2nd paragraph: “...like the American amphibians, the axolotl and the mud puppy.” I propose to change this into “...like the American amphibians axolotl and mud puppy.” since the present formulation can be understood as axolotl and mud puppy being the only American amphibians.

Anatomy: Mechano- and electroreceptors, 1st paragraph: “(Bulog, personal observ.)” I think this needs some reference?

Ecology and life history, 2nd paragraph: “The tadpoles are 2 centimetres...” I think the term ‘tadpoles’ is normally only used for the very different young specimens of frogs and toads? I suggest using the word ‘larvae’ here, even if this means using this word several times in only a few sentences.

I also second the (quite old) above sections:

1) "Did anyone else notice this?" Obviously, the display isn’t visual. But what kind of display do they use then? Do they make sounds, do they circle around each other, something else?

2) "pigmentation consistency" After some years, this inconsistency is still there. I don’t have the books, so I don’t know what to keep and what to change.

Scarabaeoid (talk) 00:16, 30 April 2010 (UTC)

Tadpole is accepted for any amphibian. For the 'display' stuff, I think it is a matter of territorial battles rather than strictly a display, with the territory controlled by one contributing to mating success, or perhaps some pheromone stuff? Display is probably not the ideal word, but is generally what is used for any sort of ritual mating stuff. As far as the pigment stuff, I'm pretty sure it just has low levels of pigment, don't have any sources on that though :P Nave.notnilc (talk) 18:36, 18 May 2010 (UTC)

Copyright/plagarism issue that needs to be corrected immediately

I nocticed that "Sensory organs" and its subsections are copied almost word for word from AmphibiaWeb. Someone needs to re-paraphrased this. LittleJerry (talk) 01:55, 2 January 2013 (UTC)

The AmphibiaWeb's author, Boris Bulog, is User:BORIS BL who contributed this section of the article, so there's no copyvio. — Yerpo 07:25, 2 January 2013 (UTC)

Jerry is correct. Unless the source is under a free license (which it's not), then this is a copyright violation–it doesn't matter if the author is the same. Sasata (talk) 07:46, 2 January 2013 (UTC)

AmphibiaWeb is not the source, but a separate publication of the same content from the same author that he chose to license differently. I understand if it seems suspicious to people not familiar with the issue, so I can ask him to provide an OTRS grant. — Yerpo 07:54, 2 January 2013 (UTC)

Please do so. LittleJerry (talk) 19:54, 2 January 2013 (UTC)
