Degu Reclassification

edit

The Degu may need to be reclassified. According to the sites listed below, the Degu is actually a lagomorph (ie rabbit, pika) and not a rodent. - M.Neko

http://www.napak.com/the_contreversial_degu.html

This issue is mentioned on the page about the family to which the degu belongs, Octodontidae (since it is the whole family, or at least a large chunk of it, that would have to be reclassified, not just the common degu) - though it probably needs mentioning on this page too since Octodon degu is much the best known member of the family. We could do with a reference to the molecular systematics work that underlies this suggestion - the web sites listed above don't give the authority, and I have been able to run it to earth, though a number of recent scientific papers refer to the degu as now being thought of as a lagomorph. Does anyone know where the evidence is to be found? seglea 23:21, 23 July 2006 (UTC)Reply
I don't think the statement belongs in either article. I have a hard time accepting pet fancy websites with bad MIDI and poor spelling as legitimate alternatives to numerous primary morphological, molecular, and paleontological sources that not only support their inclusion in Rodentia, but also well nested in the order in Hystricomorpha, Hystricognathi, Caviomorpha, and Octodontoidea. Huchon and Catzflis, 2002; Opazo, 2005; and something involving Rowe and Honeycutt are all molecular studies that support the octodontids positioned as I've just mentioned. --Aranae 01:34, 24 July 2006 (UTC)Reply
I agree that the websites listed above are not evidence at all, except that the suggestion is out there. I think the Rowe/Honeycutt paper you're referring to is probably Honeycutt et al (2003). However that does not do much with the location of Octodontoidea - it is more concerned with its internal relationships. Opazo (2005) and Huchon et al (2002) (is this the one you refer to?) are much better evidence. My problem is with papers such as Poeggel et al (2003), from perfectly respectable sources, which refer without comment to, "...the precocious lagomorph Octodon degus". Where are they getting this from? I can't get at the full text of that or other articles that say the same at the moment to see if they source it. However, looking at them more carefully, I see that (a) they all involve the same group (K. Braun seems to be the consistent figure); also (b) they are by neuroscientists not specialist taxonomists, so they may just have picked the idea up from somewhere non-authoritative. It would be good to track the idea down to its root, though. Meanwhile I will amend the pages to be sceptical, if you haven't already done so. seglea 18:31, 24 July 2006 (UTC)Reply
Many of the references you're discussing, along with a brief summary of each, can be found on Degutopia's website (http://www.degutopia.co.uk 'Degu?-Controversy' menu), FYI. Degutopia (talk) 14:47, 5 February 2008 (UTC)Reply

Plurals

edit

I belive that the plural of "degu" is "degu," not "degus." I changed all refrences of "degus" to "degu" unless it refers to the species name.

If it turns out that I am incorrect, feel free to change them back. Also, if a link stops working, it may need to be changed from "degu" to "degus," depending on which one the other end of the link uses.

It is correct. VanTucky 18:22, 6 May 2007 (UTC)Reply
Actually the plural form of degu appears to be degus

Illegal

edit

I have heard on a discussion board that a woman, living in Pennyslvania, talked to a local pet store owner who said they are not allowed to sell degu anymore. If this is true, which i'm still trying to find more information regarding this, this should be added to the article. Furik 22:21, 31 May 2007 (UTC)Reply

How big are they?

edit

Seriously - this info is missing. I came for a quick look to see what a 'degu' is, and although I now know some handy hints on how to keep one, I don't know how big they are. Justinep 23:18, 6 August 2007 (UTC)Reply

In terms easily understood, they are about the size of a baseball. They do not get bigger than an adult rat. I am a girl with reletively small hands and I can easily hold two degus in one hand at a time. Hope this helps. Jsouth2 00:27, 19 September 2007 (UTC)Reply

Removable Tails

edit

I was surprised that the page did not contain a single warning about degu's tails coming off if grabbed. I made that huge mistake this morning, now my degu will only have half a tail for the rest of it's life.

I guess that's what I get for only using wikipedia to research a pet before I buy one. The makuta 03:32, 14 September 2007 (UTC)Reply

It is not generally thought a good idea to grab any animal by the tail, at the very least this will cause an animal discomfort. --Shearluck (talk) 12:50, 2 April 2008 (UTC)Reply

raised for meat?

edit

were these animals ever raised for their meat by Amerind peoples in the same way Guinea Pigs were (and still are)? --86.148.57.131 (talk) 01:08, 8 January 2008 (UTC)Reply

Archaeological evidence has been found for humans hunting and eating degus in the recent past (Ebensperger & Wallen, 2002), but not raising them for their meat. This is likely to be because of their small body size and burrowing nature, therefore being harder to contain and of less relative calorific value than the Guinea pig.

Bad diet advice?

edit

in the 'keeping degus' section it advises:

Degus also enjoy tomatoes and cucumber peelings. When feeding produce be sure to thoroughly wash it off; and in addition scrub cucumber skins to remove any wax or other coatings.

However Degus should not be fed foods containing sugars (as is noted in the 'diet' section).--Shearluck (talk) 12:45, 2 April 2008 (UTC)Reply

Degus should not be regularly fed foods continaing free sugars. Research has shown degus are in fact able to metabolise dietary sugars, allbeit at a much reduced rate, hence they are much more prone to developing diabetes mellitus (see Opazo et al. (2003) for example). Degus can therefore have the occasional bit of fruit or vegetable containing some free sugars, but not on a regular basis (see the 'diet'[1] and 'role of sugars in the degu diet'[2] pages on Degutopia's website for further information). In fact, fresh vegetable matter is an essential part of the captive degu's diet in order for them to obtain compounds such as essential amino and fatty acids that cannot be incorporated into dry feeds.

Induced Ovulators

edit

Degus are not induced ovulators. They have normal estrus cycles, but do go right into estrus most times after they give birth. We predict their cycles in my lab based on their circadian activity patterns. Here's some info, and a great article for someone to do some citations with. http://dels.nas.edu/ilar_n/ilarjournal/45_1/pdfs/v4501lee.pdf 147.124.152.143 (talk) 03:35, 22 April 2009 (UTC) mckelvyad —Preceding unsigned comment added by 147.124.152.143 (talk) 03:32, 22 April 2009 (UTC)Reply

My Degus' strange behavior

edit

I had degus once, but they didn't like us and always bite us really hard. And I know these creatures are affectionate and intelligent to their owners, but ours were dowright mean. How is this possible for them to be like that if most degus show love for their owners? The Winged Yoshi


You obviously didn't treat them well enough. 99.140.232.84 (talk) 06:42, 24 April 2009 (UTC)Reply

Pronounciation

edit

How do you pronounce 'degu' (if you're from the UK)? And also I might have spelt pronounciation wrong Melon247 (talk) 18:58, 1 February 2009 (UTC)Reply

In the UK and US, degu is pronounced "day-goo". The plural, degus, is pronounced "day-gooz". Note that this is pronounced differently to the species name (Octodon degus) which is "Ok-toh-don day-guss". Degutopia (talk) 10:30, 24 July 2009 (UTC)Reply

Diet section

edit

Several sources and information in this section are misleading or at least a bad choice, because there are better studies to a given topic:

  • Diet of degus is described and reviewed in several studies. Basic work was done by Peter L. Meserve in 1980s, earlier findings are reviewed in Woods & Borakers mammalian account. In the 1990s Chilean researchers published in the spanish Revista Chilena de Historia Natural, the importance of the Wine Palm nuts (Coquitos) as seasonal food item for the degus.
  • Dried food is of course part of their diet, but they always rely also on frehs food. If annuals dries out, degus shift to sclerophyllous shrub species.
  • "degus are specially adapted to a very high fibre intake" cites a review about adaptions in animal guts in general, IMHO not the best choice and it contradicts to findings of Chilean researchers pointing out, that degus prefer low fibre diets. Also a rate of about 25% seeds is relatively high for a herbivorous rodent (keep in mind that the amount of seeds in the diet of other herbivores like cavies or rabbist is much lower, typically below 10 %).
  • "and this varies between food types and environmental conditions" -> laks specific details: what does variation between food types mean? How does the environmental conditions change? This might be of importance.
  • "This also serves to maintain healthy gut function during times when food is scarce." this is an assumption, but there are several assumed explainations for coprophagy: e.g. production of vitamins, increasing digestion efficiency, etc.
  • "Although they are active by day, in high summer they do not leave their burrows in the middle of the day" -> wrong section, it describes activity or behaviour of the degus (bimodal activity)
  • "Because of this it is important to check the ingredients of non-degu specific hard feed formulations for free-sugar substances, such as molasses, honey and glucose syrup." -> is this of importance for wild degus?

Natural Range

edit

Is there a natrual range for degus? I see this is part of the Chile portal, but that is the only reference to where they exist in the wild. — Preceding unsigned comment added by Vettrock (talkcontribs) 14:41, 14 June 2015 (UTC)Reply
