Article Grading: The following comments were left by the quality and importance raters: (edit · refresh) I can only repeat Stefan's comments on this talk page: "I can not find anything about what crabs eat, how long do they live, there is a passing remark to them carrying eggs in reference to different body shapes, but no description of reproduction, the headings seem to be randomly named and often talk about many other things, I'm expecting headings like Physical characteristics, senses, behaviour". Needs expanding and reorganising. IronChris | (talk) 04:48, 18 November 2006 (UTC) The article has re-organised extensively and expanded slightly since Stefan's comments were posted. There is now a diet section, and an anatomy section (so covering "what crabs eat" and "physical characteristics" suggested above). Lifespan, behaviour and other similar topics are very variable within the group, making it difficult to write a meaningful text. --Stemonitis 15:49, 1 December 2006 (UTC) WikiProject Food and drink      (Rated B-Class) Food Portal This article is within the scope of WikiProject Food and drink, a collaborative effort to improve the coverage of food and drink articles on Wikipedia.

Crab was a good article nominee, but did not meet the good article criteria at the time. There are suggestions below for improving the article. Once these are addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake. Reviewed version: October 6, 2006

do crabs claws go back?

How about links to the various crab species?

Amen to whoever wrote that. This article needs links to tie together to some of the zillion types of crabs in various Wikipedia articles, including all of them in Category:Crabs, including grouping them in ways we don't get in the bald category listings. Gene Nygaard 05:34, 27 February 2006 (UTC)

[edit] Picture of baby crab

I added a picture of a (what I assume is a) baby crap Image:Baby crab.jpg. It wqas removed by annon user 193.190.112.194 who said that it has no encoycopedic value[1]. While I admit it is not of overwelming scientific value, would it not be a good idea to have a picture of a baby crap to show the development of crabs?--JK the unwise 14:56, 16 February 2006 (UTC)

As no one has replied I'm going to re-add the picture.--JK the unwise 13:08, 27 February 2006 (UTC)

what are cras adaptive features?

I mean crabs

[edit] Sexual dismorphism

Sometime I've read in a magazine (an old "super interessante") that the portuguese like to fish male crabs to remove their larger claw and then they free the crab so it's claw will grow again, and when the claw is growing the other crabs think he is a she-crab instead and the poor mutilated crab doesn't get to mate with shecrabs, is this true? 201.23.64.2 23:09, 1 June 2006 (UTC)

I have read that stone crabs (genus Menippe) became very popular as food recently, and are now endangered. Fishermen now try to reduce the risk of its extinction: since most of the best meat is contained in the large claw, they cut the claw off and release the crab to grow a new one. On the contrary, they don't do it out of cruelty. --Crustaceanguy(t/co/cw) 13:43, 20 May 2007 (UTC)

[edit] GA Concern: Embedded List guideline

A GA reviewer would have trouble passing this article, because it fails criterion 1(c). Please review the list guidelines. -Fsotrain₀₉ 00:19, 3 October 2006 (UTC)

Point taken — list moved to taxobox. --Stemonitis 08:06, 3 October 2006 (UTC)

Thank you for acting so promptly, and replying. I have cleaned up the list some, and I believe it would now pass that criterion. -Fsotrain₀₉ 17:13, 3 October 2006 (UTC)

I'm unsure about the value of removing red links, but if you think it will help, then so be it. There was a bit of a mistake in the taxobox, which I have now sorted out. --Stemonitis 17:19, 3 October 2006 (UTC)

It's not the existence of redlinks, its that the list consisted almost entirely of them. I do think dewikification was warranted here. I apologize for the error I made. --Fsotrain₀₉ 18:14, 3 October 2006 (UTC)

[edit] GA coments

I will not fail this article, just give some of my comments, not really sure how strict to be so I let someone with more experience in assessing GA do it. I think it fails requirement 3) I.e. coverage, Im not sure what is know about crabs, but I can not find anything about what crabs eat, how long do they live, there is a passing remark to them carrying eggs in reference to different body shapes, but no description of reproduction, the heading seams to be randomly named and often talk about many other things, I'm expecting heading like Physical characteristics, senses, behaviour. Stefan 15:11, 5 October 2006 (UTC)

I'm afraid I agree: I'm a biology student, and still find this article relatively disorganised and hard to read therefore. Needs substantial expansion and reorginisation. That said, almost all of what is there is of quite high quality, and will, if rearranged a bit and the missing information added in, be a fine part of a featured article Adam Cuerden ^talk 12:31, 6 October 2006 (UTC)

[edit] brains

do a crab have a brain an a heart??

Yes, crabs and other crustaceans are in fact relatively complex animals. They have a brain, a heart, and many other important organs.--Crustaceanguy 13:43, 8 April 2007 (UTC)

[edit] do crabs eat peeople

Do crabs eat people

yes they do. Infact they must've eaten you by now. 202.1.192.6 16:59, 6 April 2007 (UTC)buzzangie

Man-eating crabs? I do not think it's likely, but not impossible. The only man-eating crustaceans I know are a few amphipods.--Crustaceanguy 13:59, 8 April 2007 (UTC)

I seriously doubt that a crab would bother to try killing a human being, but I think it's likely that some crab species would feast on corpses found in the water.--Gunnar Mikalsen Kvifte 05:00, 7 August 2007 (UTC)

[edit] Walking sideways

i came on here to find out some questions my little brother asked about why do they walk sideways, and can they walk forwards? there isn't any mention of that at all. —Preceding unsigned comment added by 24.19.3.231 (talk • contribs)

There used to be a short discussion of it, but I think it was removed because of a lack of references. Most crabs walk sideways most of the time, because it's easier given the way the joints in their legs bend. However, plenty of crabs are perfectly able to walk in any direction they please. The quote at Grapsus grapsus illustrates the agility that many crabs possess. --Stemonitis 19:25, 19 January 2007 (UTC)

[edit] Identification

I took this photo at Croajingolong National Park on the east coast of Australia. Someone told me it was a "soldier crab". Can anyone confirm or be more specific? Stevage 04:28, 20 January 2007 (UTC)

[edit] Please help to identify this crab

I bought this crab at the supermarket and didn't want to eat it lol, can anyone tell me what's the name of this breed ? (in the green picture) Thanks a lot ! --AlexMilkis 15:57, 29 January 2007 (UTC)

It's a freshwater crayfish, not a crab. It's difficult to identify it further without knowing where it's from. --Stemonitis 16:46, 29 January 2007 (UTC)

[edit] New Species should be listed

As Wikipedia will not let me edit the "Crab" page, I might as well just put this here-

in 2005, a new crab species was discovered that was nicknamed the "Yeti Crab". Heres some random information on it- http://www.mbari.org/news/homepage/2006/yeti-crab.html —Preceding unsigned comment added by 68.188.215.93 (talk • contribs)

See Kiwa hirsuta. Also note that it is not actually a crab. --Stemonitis 13:33, 16 February 2007 (UTC)

[edit] Fossil Crabs

Wouldn't it be nice to have a little more info about ancient crabs and crab evolution? Some pics of fossil crabs would be awfully good as well.

[edit] On "diet"

With crabs being such a diverse group of animals, it is questionable to claim that they mostly feed on algae citing a study of just one of several thousand species as evidence. Pea crabs, for instance, feed exclusively on plankton.--Gunnar Mikalsen Kvifte 05:00, 7 August 2007 (UTC)

Cromer crabs. The Cromer crab is a very special species surviving massive drops off the local pier on a regular basis. Some may see this as in humain however recent studies show that if once caught the crabs are not dropped back in from the pier but let loose on the beach the survival rate is thought to be much slimmer. —Preceding unsigned comment added by 81.79.71.230 (talk) 18:32, 26 September 2007 (UTC)

[edit] Massive Damage?

In the unlikely event of a giant crab encounter, where should I strike to inflict massive damage? Thanks!

I would think somewhere near their eyes, going for the brain. —Preceding unsigned comment added by 24.77.19.12 (talk) 19:28, 23 February 2008 (UTC)

[edit] Kayewees?

There is something odd here. the article Kayewee seems to be the first bit of the crab article that someone has copied, replacing "crab" with a nonsense word. As a new user could someone please give me the procedure for deleting pages that are probably vandalism? —Preceding unsigned comment added by 99.235.249.229 (talk) 19:52, 27 March 2008 (UTC)

[edit] Vandalism

removed this:

The crab is named after Patti Knetz after her discover of the disease. She was the first known victim of the dreaded "crabs". Extremeologist T Scott believes that she first contracted it from sitting at her desk all day looking at student's facebooks. 161.45.14.114 (talk)
