Talk:Coconut crab

Living Fossil
Living fossil, or convergent evolution with something VERY old? I'd like to see differences with the original terrestrial anthropods specifically crabs. The path to spider is merely more suitable terrestrial lungs, terrestrial eggs and then the loss of the then useless 9th and 10th legs..

Hey guys. Vacationing in Jamaica for my 13th birthday, I was coming back to my room from the a club one night around midnight. I was walking up a set of stairs when something large and heavy fell on my head, literally. I looked down surprised and saw the biggest "spider" I had ever seen! I immediately shrieked and stomped on it. It was destroyed rather easily and after my initial freight I was deeply saddened for killing a living creature, (even though I am deathly afraid of spiders). I didn't know what it was until recently, (some 13 years later). But I wanted to say it was brown and blackish, with out claws/pinchers. I remember the next day a little drama unfolded when the workers were asking around to see who had killed the creature and if they had been attacked. I figured it was an endangered species or something so I kept my mouth shut. But this was a terribly tragic experience for me, and I just wanted to share it.

 * According to the range information, coconut crabs are not found in the Atlantic Ocean. SlowJog (talk) 22:43, 26 May 2009 (UTC)

I think that references to Coconut Crabs (Birgus latro), commonly called Robber Crabs on Christmas Island, being a metre or so in size are highly exagerated. I was the Government Conservator with Parks Australia North on Christmas Island during 1997/98 and can state that they do not reach this size. Dr Holger Rumpff is spelt with 2 'f's. He is a sadly missed friend and colleague who was an expert on the ecology of Christmas Island. In addition, he was a superb wildlife photographer. David Murray

The error is still on the front page. You might to fix the steal part. --Cyberman 00:15, 10 Feb 2005 (UTC) Ok it's fixed now. ^_^ --Cyberman 00:21, 10 Feb 2005 (UTC)

Only the other day someone at reference desk was mentioning that we don't have an article about the coconut crab. Amazing that this article came up in just 2 hours. Good work Chris! Jay 18:40, 12 Jul 2004 (UTC)


 * Yeah! Great work! Mark Richards 22:48, 12 Jul 2004 (UTC)


 * Thanks. I saw the question at the reference desk, including the photo found by Mark Richards. Thought it would be a waste to have such a nice photo with no article to go with. I'll be also checking some german links soon, which seem to have some additional info. -- Chris 73 | Talk 02:25, 13 Jul 2004 (UTC)

Added the statement about Christmas Island having the largest population based on this link: http://www.wilderness.org.au/campaigns/marine/christmas_island/save_ci/. Though this is not an authoratitive scientific source, I considered it reputable enough to use. Disclaimer: I grew up on Christmas Island and am fond of the place (and it's crabs). Congrats on the great work you've done on this article Chris -- Oska 06:09, Jul 13, 2004 (UTC)


 * Thanks for your editing. Most of my sources are different webpages, and very few are peer reviewed scientific journals, so your source is just fine. Actually, I had the feeling that the habitat was not yet complete, and I was missing a few spots. Thanks for the update. Chris 73 | Talk 06:27, 13 Jul 2004 (UTC)

A couple of comments
Nice article. Just a couple of comments:


 * The bit about opening coconuts in the wild but not in captivity is fun, but the final piece (just why can't the crabs open them in captivity) is missing.
 * The german bio could do with being created
 * And the lung bit

I'm not a bio so don't want to myself :-) (William M. Connolley 16:30, 9 Oct 2004 (UTC))


 * Oopening coconuts: Probably nobody knows. Maybe the crabs were too small, the coconuts too old or unripe, or the wrong coconuts, maybe they died not of hunger but e.g. lack of water, or - my preference - they were just scared shitless in the laboratory environment and too stressed to open coconuts.
 * The german bio could do with being created Holger Rumpff? I'll see what I can do
 * And the lung bit Not sure what you mean
 * Thanks for the feedback. -- Chris 73 Talk 11:49, Oct 11, 2004 (UTC)
 * This bit: The crabs cannot swim and will drown in water. The crab uses a special organ called a branchiostegal lung to breathe.
 * Holger Rumpff: I searched the web and could not find any biographical information of him. The only thing I found was "This work is dedicated to the memory of Dr. Holger Rumpff, without whose enthusiasm ..." here and here. Seems to be not very notable, so I unlinked his name in the main article, and probably won't create an article. If you find more and write an article, please feel free to link it again. Searching Google for "branchiostegal lung" OR "branchiostegal lungs" -wikipedia brings up a few references, I may make a stub about that. -- Chris 73 Talk 14:23, Oct 11, 2004 (UTC)

He's called Rumpf (one 'f') in 2 german press articles, here http://www.diepresse.at/Artikel.aspx?channel=r&ressort=ra&id=457876 and here http://www.mdr.de/windrose/archiv/471738.html Worth looking into perhaps? Prater 22:04, 10 Feb 2005 (UTC)

Child's play
The Cultural paragraph on children playing with coconut crabs sounds like encouragement to engage in animal cruelty. Surely this is not the intent. If this is an actual common practice, can we at least say something factual like "children sometimes play" or even "children often play", rather than a permissive "children may play", so as not to condone the practice? (I'm no animal rights activist, but I see no point in appearing to recommend amusement by getting other creatures to harm themselves.) &mdash; Jeff Q 03:32, 10 Feb 2005 (UTC)
 * Good point. I reworded it as suggested -- Chris 73 Talk 04:08, Feb 10, 2005 (UTC)
 * I sure wouldn't let my kids play with one... not if I liked the idea of them having fingers. PenguinJockey 01:24, 28 May 2007 (UTC)

Sense of Smell
Did you guys read the recent article over at BBC? I think it's worth including the new information on the creature's sense of smell, if you feel like it.

And by the way, good article! --Polyparadigm 04:52, 10 Feb 2005 (UTC)


 * Thanks for the info. Added a section. How does it look? -- Chris 73 Talk 05:22, Feb 10, 2005 (UTC)


 * Looks great! Man, that was fast.--Polyparadigm 07:18, 10 Feb 2005 (UTC)
 * (Chris patting himself on the shoulder with a satisfied look) :) -- Chris 73 Talk 07:26, Feb 10, 2005 (UTC)

Size
These creatures are big, but how big? I did a little checking around, and found sizes ranging from 40 cm to over a meter, and weights from 3 kg to 17 kg. This is also a long-lived species, apparently, achieving maximum size after 40-60 years. If someone can confirm this info it would be good to include with the article. -- Mmm 16:08, Feb 10, 2005 (UTC)


 * Saying 'from head to tail' is bad usage, because crabs don't have heads or tails. But I also think the size of one meter is reached only when measuring the other way: from claw to claw. Prater 17:28, 10 Feb 2005 (UTC)
 * I tried to incorporate the variations of the different sources in the article -- Chris 73 Talk 04:11, Feb 14, 2005 (UTC)
 * No way in hell is this thing's leg span 2 m. That's just not true. It's 1 m, at most. Jerkov (talk) 14:57, 15 June 2008 (UTC)
 * I just edit that part. After looking through yahoo and google results, National Geographic came back as the only source that I find reliable. They says coconut crab can have a leg span of "more than 3ft (1m)". I know that 1m is actually closer to 3.3ft. Usually when I see numbers like this, I assume that the number inside the parenthesis is rounded off after conversion to make it easy for the readers. So I think the actual leg span is "more than 3ft." The age is listed as "more than 30 years." http://www.nationalgeographic.com/wildworld/profiles/terrestrial/im/im0125.htmlElsonlam1 (talk) 05:43, 2 September 2008 (UTC)

"Coconut Crab"?
Why is "Coconut Crab" consistently capitalized, even in the title? Compare for example hermit crab. &mdash; &#1051;&#1080;&#1074;&#1072;&#1081; | &#x263a; 21:20, 10 Feb 2005 (UTC)
 * Compare fx "cat" :). I fixed it. Thue | talk 22:41, 10 Feb 2005 (UTC)
 * Species names are capitalized. See Red-throated Diver, Black-crowned Night Heron, Australian Land Hermit Crab, Ecuadorian Hermit Crab, et al. It is hermit crab which is incorrect. it should be Hermit Crab. If you want to find the lengthy dialog on this decision, I can track it down. it occurred over a year ago. Kingturtle 23:16, 10 Feb 2005 (UTC)
 * Thanks for informing me. No need to track down the discussion itself. I figured there must have been some reason it was written like that and not changed; now my curiosity is satisfied. &mdash; &#1051;&#1080;&#1074;&#1072;&#1081; | &#x263a; 03:22, 11 Feb 2005 (UTC)
 * Why isn't all instances of "cat" capitalized? *curious* Thue | talk 23:49, 10 Feb 2005 (UTC)
 * If you are referring to cats, wild species of the family Felidae are capitalized: Black-footed Cat, Flat-headed Cat, Canadian Lynx, Bengal Tiger, Indochinese Tiger, Clouded Leopard, etc. Breeds of domestic cats also utilize the same capitalization rule: Maine Coon, Turkish Angora, British Shorthair, Egyptian Mau to name but a few. All of these species are catagorized officially by scientific groups. But breed names are more tricky - and might not always fall into official catagorization. There may also be some instances outside of the scientific categorization of kinds of cats - and such instances won't follow the capitalization rule, such as Feral cat. I hope this helps. :) Kingturtle 01:30, 11 Feb 2005 (UTC)
 * This is a highly contentious issue. If it were up to me, I'd say only birds should be capitalised, and as it says at: Naming conventions (fauna) -- and see also the associated talk page. Wikipedia articles have gone crazy capitalising all species from Blue Whale to Dingo for some weird reason. If there was a vote on the issue I'd say "coconut crab" with small c's and "dingo" with a small d. Further debate should probably be on the Naming conventions (fauna)'s talk page. --Pengo 08:09, 12 Feb 2005 (UTC)
 * The symantical reason for the capital letters is simple. it distinguishes between a black bear (any bear that is black) and a Black Bear (a bear of the Ursus americanus species). Kingturtle 17:32, 12 Feb 2005 (UTC)
 * If it were up to me the difference would be between "black bear" and "blackbear" (like "blue bird" and "bluebird") but hey, I don't write the dictionaries. Whatever works I guess... &mdash; &#1051;&#1080;&#1074;&#1072;&#1081; | &#x263a; 10:15, 15 Feb 2005 (UTC)

There is no good reason for capitalising species names, and absolutely no reason to capitalise hermit crab, since that refers to a group of animals, not to a single species. As far as I can see from the discussions, only ornithologists routinely use capital letters for species names (which they consider to be somehow official, i.e. tied to a particular scientific name); everyone else should be using lower case, except where appropriate for other reasons (e.g. Norway lobster). There is certainly no fixed list tying common names for crustaceans to scientific names, so the names cannot be considered in any way official. Since they are not proper nouns, therefore, they should not be capitalised in English. I suggest this article be re-named (or un-renamed) "Coconut crab". Stemonitis 15:24, 18 Feb 2005 (UTC)

WHY was this changed back from Coconut Crab to Coconut crab? The case has been stated exactly WHY this article should be Coconut Crab. Please explain the change to Coconut crab. Kingturtle 18:19, 2 Apr 2005 (UTC)

For the reasons stated above, and others too, not least consistency within the Crustacea; all crustacean articles are uncapitalised, as are many (most?) other arthropods. A while ago I looked at the crustacean articles and saw a huge mixture of capitalised and uncapitalised forms, perhaps with a majority uncapitalised (I can't honestly remember). I looked up the relevant style guides and discussions and discovered that outside of bird species names, there is no real consensus. I therefore picked what made sense to me, and made them consistent. If you want it to be "Coconut Crab" again, then you would have to capitalise all the other crustacean species as well (note that since hermit crab is a group, not a species, that rule needn't apply to it - that would need to be included in the discussion). I recently requested a couple of moves to lower case, for consistency's sake (e.g. American lobster), and they were approved by the community. I took that, and the silence following the change here as evidence of acceptance of my choice. Of course, if you know of any reason for the coconut crab to be treated specially, please say so. --Stemonitis 14:52, 4 Apr 2005 (UTC)


 * I am in the camp that it should be Coconut Crab. Read my reasons above for this position. I'd be willing to take the time personally to make such changes to ALL articles that would need to be changed to make this consistant. Kingturtle 01:41, 5 Apr 2005 (UTC)

Another Name
The Coconut Crab is also known as "Bubble Crab".
 * No references found online in connection with the coconut crab -- Chris 73 Talk 03:45, Feb 14, 2005 (UTC)

In Portuguese it is named "Caranguejo-de-Bôlha"(i.e Bubble's Crab) perhaps in another related languages is also.

In the Northern Part of the Philippines they are called Tatos and they are a delicacy 19:30, 3 December 2007 (UTC)berwynson

Thief?
"It is sometimes called the robber crab or palm thief (in German, Palmendieb), because some coconut crabs steal shiny items such as pots and silverware from houses and tents."

I would like to see proof of such behaviour, else it should be described as rumored. Most Coconut crabs are in fact not theives at all.
 * In Dutch it is also called klapperdief, which means thief of coconuts. It 'steals' (and even that is not fully documented) coconuts from the trees, but nothing else... Lycaon 22:25, 23 April 2006 (UTC)
 * That a crab would steal silverware seems highly unlikely since they would have absolutely no use for them and, judging by the information here, doesn't seem to have either the eyesight nor the intelligence to actually appreciate shiny objects. However, I've seen a photo of a robber crab in the midst of climbing up a trashcan (presumably in search of food). That might be one way of how they could be perceived as theives of something other than coconuts.

word choice
apomorphic is poor use in an encyclopedia article. I realize a blu link helps define the term and that it is a good specialist term. Still bad usage in wiki. I think I will write an essay on this growing practice. 72.82.52.106 (talk) 16:24, 10 April 2009 (UTC)

distribution
Map does not match distribution. Map shows Taiwan, etc. having crabs, but this is not mentioned in the text. Also, the map does not call out the features described in the text, for instance Christmas Island. Let's push ourselves more to make a quality product. Give people what they would get in a pay encyclopedia. Then we can talk about wiki being better than Britanica. 72.82.52.106 (talk) 12:40, 11 April 2009 (UTC)

The article states that the eastern limit of distribution is the Gambier Islands. This is not correct, as the Pitcairn Islands are further east than the Gambier Islands, and theh coconut crab is well known there. There was even a Pitciarn Islands stamp issue featuring it in 2008. Arkive (http://www.arkive.org/coconut-crab/birgus-latro/#text=Range) states that there are reports of it from Pitcairn Islands, and even as far east as Easter Island, though I cannot otherwise confirm that the latter. But my wife grew up in Pitcairn, and confirms their presence there. Ptilinopus (talk) 06:56, 22 June 2012 (UTC)

Former Featured Article Rescue
Just in case anyone's watching, I should warn ye that I plan to restore this article to its former FA glory, so don't be alarmed by the changes. Wish me luck! Sasata (talk) 05:17, 15 April 2009 (UTC)

Image with human in it?
It would be nice to have an image of the crab with either a human person or else some object of well-known size in it (match box, box of cigarettes, dollar bill etc.), so that the size of the animal can be made visually obvious. Thanks! -- 92.229.105.68 (talk) 15:39, 17 February 2010 (UTC)

Sympatric with man??
Was it really necessary to say the crab is "sympatric" with man merely to say their territory overlaps?? Except for the bottom of the sea and wild reserves, are there any species anywhere on Earth that are not "sympatric" with man? I am not a biology or evolutionary expert but it seems to me this word was not meant to be used in this context. 24.214.155.48 (talk) 18:49, 29 March 2010 (UTC)

Do you know how many of these topics are covered by recent reviews? Where possible, we should be trying to use the secondary literature. I would hope that Drew et al. (2010) would discuss most important aspects of the species' biology, for instance. I see no problem with going back to the primary literature to fill in some details, but I don't think we should expect to include the results of every research paper. --Stemonitis (talk) 07:00, 2 September 2011 (UTC)
 * Of course, we won't be using them all (I probably won't even be able to access several), but we can't claim that the article is well-researched and comprehensive unless a good effort is made to survey the available literature. Sasata (talk) 14:35, 2 September 2011 (UTC)

Conservation
The Coconut crab is a protected species on Diego Garcia. The crab in the photo is one on Diego Garcia. The photo is germain to the section and to the article. --Revmqo (talk) 14:15, 23 November 2012 (UTC)


 * But there's no way of seeing from the image that it's in Diego Garcia, and so it doesn't illustrate that fact. It's just another picture of a coconut crab, with nothing special to recommend it. It's not at particularly high resolution; it's not particularly well composed. Indeed, Diego Garcia isn't even mentioned in the Conservation section, so it couldn't possibly be illustrating that. It adds nothing that isn't already shown by the existing images, and thus fails WP:IUP. --Stemonitis (talk) 15:04, 23 November 2012 (UTC)

Adult survival in water - seeming inconsistency
The article states more than once that adult coconut crabs will drown in the ocean, but also says that reproduction happens in the water, with adult crabs having been found as far as 6km offshore. Can someone reconcile these pieces of information? --170.145.0.100 (talk) 17:29, 10 February 2014 (UTC)
 * Current reading of the article is that fertilization takes place on land, but hatching eggs are released at the shore line. And the 6km is inland, not offshore. 192.4.0.12 (talk) 20:02, 7 August 2014 (UTC)

This article also says that the crab will die if left in salt water for an hour, and in another section, says that it will die if in water "less than a day". Reference 11 vice reference 18. Unclesmrgol (talk) 06:49, 24 November 2016 (UTC)

Coconut is not a nut.
It's a Drupe according to the following Wikipedia articles:

Can someone knowledgeable about this subject edit the article to reflect that please? 50.170.31.164 (talk) 20:16, 11 April 2016 (UTC)

Amelia Earhart (again)
I've removed the claim that coconut crabs may have consumed Earhart's remains, as per the discussion on her talk page. This species faces enough threats to its population, without tabloidy scaremongering ~dom Kaos~ (talk) 14:47, 10 November 2017 (UTC)


 * I don't see the discussion you linked, but I'm guessing that's just because that talk page was cleared since then, since this talk post is pretty old. Regardless, the validity of the whole "eaten by coconut crabs" conspiracy theory (And let there be no doubt, it is a conspiracy theory) is pretty irrelevant to the cultural phenomenon surrounding it. I've readded a mention of this in the "Relationship with humans" section, alongside a rebuttal of it as anything aside from a conspiracy theory/internet meme. I think it'd be better to bring it up and then refute it than to pretend that it doesn't exist at all, especially since several edits appear to have been made/undone since then that express this in a more matter-of-fact way.

hunting birds
Someone reversed my edit and said that it didn't belong in the introduction. I selected that placement because that is where the article was talking about what the crabs eat. Where should I put that there is some evidence they hunt birds? Most Humble and Obedient Servant (talk) 23:08, 9 March 2021 (UTC)

apex predator?
This critter has been entered into Category:Apex predators. Can anyone explain why it might get that designation? What animals does it prey upon?--Mike Selinker (talk) 00:50, 29 March 2021 (UTC)
