Untitled[edit]

There should be a way to navigate to this page from the penguin page. --zandperl 20:22, 5 Apr 2004 (UTC)

Look under the classification section:

Family Spheniscidae

King Penguin, Aptenodytes patagonicus
Emperor Penguin, Aptenodytes forsteri
Gentoo Penguin, Pygoscelis papua

My bad, I completely missed that! :-P --zandperl 01:41, 6 Apr 2004 (UTC)

Etymology[edit]

The name gentoo comes from the French language, being a corruption of the word ghetto meaning "Poor" or "Senial". During the 18th century, the name was also applied to members of the Hindu faith.

This sounds wrong to me. The word ghetto is not of French origin (rather Italian, see http://en.wiktionary.org/wiki/ghetto ) and does not mean "poor" or even "senial" (which does not seem to be a word at all). Furthermore, as someone else has indicated, this assertion is somewhat undocumented. I googled quickly ('gentoo'+'hindu') and found the following, amongst others: http://www.communigate.co.uk/ne/penguins/page6.phtml http://www.raceandhistory.com/historicalviews/NoDefinitionofHinduism.htm

What we can clearly establish is that "gentoo" was/is a derogatory term used to refer to Hindus (and others) by both British (possibly a corruption of "Hindu"?) and Portugese (from 'gentile').

I'll remove the reference to French, at least.

Contradictions in the diet[edit]

One sentence tells us: Gentoo penguins are opportunistic feeders, and [...] take roughly equal proportions of fish, crustaceans and squid, and the next says Gentoos live mainly on crustaceans, [...] with fish making up only about 15% of the diet. Well, which is it?

Life Cycles of Gentoos[edit]

How long do they live for?[edit]

I've search many sites and not one gives a live span of the Gentoo. Book report due Thurs. Help

500,000 g Eggs ?!?[edit]

I'm sure there is something wrong with this. How could a 7 kg creature lay an egg of 500 kg ? I changed it to 500 g, but I'm not sure of the actual weight of their eggs. (~Drysh)

Simple vandalism. It's a real shame that almost nobody ever seems to get the idea to check the history when they see something extraordinary/incredible but unexplained or plain illogical in an article. Had you done that, you'd have noticed that the original figure given was 130 g. After seven years, the vandalism was still basically uncorrected. --Florian Blaschke (talk) 00:43, 12 December 2013 (UTC)[reply]

Eggs[edit]

"Two eggs are laid, both weighing around 500 g." Is that each, or in total? GrahamBould 12:55, 4 May 2006 (UTC)[reply]

Pronunciation[edit]

dʒɛntu?? shouldn't it be something like jĕn`tŌ´ (from thefreedictionary.com) is there some wikipedia sanctioned pronunciation scheme that I missed?

No, it is correct as is. Look at International Phonetic Alphabet for English. /ˈdʒɛntu/ as the English pronunciation spelling would be exactly like [jen-too] (Dictionary.com Unabridged (v 1.1)). 97.86.248.2 21:29, 7 October 2007 (UTC)[reply]

Creches[edit]

"The chicks remain in the nests for about 30 days before forming creches." The "Creche" link redirects to "Crèche", which is a stub, saying it can mean "Day care centre" or "Nativity scene". So, wtf? Do the 30 day old chicks build themselves a little fort out of snow or clay? Or is there a third sense of the word, referring to some type of plumage? More info? Citation? --Infinoid 16:04, 29 June 2006 (UTC)[reply]

Original Research[edit]

"The Gentoo are the most timid species of penguin."

I believe that the above is original reseach and that it should have a citation or be deleted. Teak the Kiwi 17:11, 7 January 2007 (UTC)[reply]

Probably taken from another source, but should have a cite in any case. Feel free to whack in the meantime, it could also be vandalism (vandals like the penguin articles for some reason). Stan 17:52, 7 January 2007 (UTC)[reply]

Physiology[edit]

Because Gentoos live in the frozen Antarctic, there is not much fresh water available to them. Much of the Gentoos' diets are high in salt so to counteract this, they eat organisms that have relatively the same salinity as sea water. This can still lead to complications associated with high sodium concentrations in the body, especially for Gentoo chicks. To combat this, Gentoos, as well as many other marine bird species, have a highly developed salt gland located above their eyes that takes the high concentration of sodium within the body and produces a highly saline-concentrated solution that drips out of the body from the tip of the beak.^[1]

Gentoo penguins do not store as much fat as the Adelie penguin, their closest relative, because Gentoos require less energy investment when hunting. The net gain of energy after hunting is greater in Gentoos than Adelies, so Gentoos do not need large energy stores as adults.^[2] As embryos, Gentoos require a lot of energy in order to develop. Oxygen consumption is high for a developing Gentoo embryo. As the embryo grows and requires more oxygen, the amount of consumption increasing exponentially until the Gentoo chick hatches. By then, the chick is consuming around 1800 mL O₂ per day.^[3]

Add section explaining how Gentoo penguin inspired the name for Gentoo Linux[edit]

The Linux distribution Gentoo Linux is named after the Gentoo penguin.^[1]^: 383 Should a part of this article mention this?
