Peer Review
Overall, I think you added nice detail about the different characteristics of the NCLDV's in the article. However, the introduction is still a bit technical. Perhaps you could revise the introduction and provide a definition of NCLDV's and a bit of history and discovery. It may be useful to add a table with comparisons of the NCLDV's to viruses and their giant virus counterparts just for quick info about genome size. Karate bb (talk) 16:09, 7 December 2017 (UTC)

This is like the worst wikipedia page I've seen and I've probably read thousands. I mean I can read about advanced nuclear theory on here at 4am and it makes sense but this is completely unreadable. Forget a layman, even smart people won't understand anything written here. This is supposed to help people learn about what it is, not confuse them. I'm sure someone felt all smart and superior writing this but this isn't a technical manual, it's WIKIPEDIA. — Preceding unsigned comment added by Moonjumps (talk • contribs) 09:47, 7 March 2014

Fourth domain of life?
According to a recent study giant viruses may represent a fourth "supergroup" of life, along side archaea, bacteria, and eukarya. Should this be added? -- 76.65.131.248 (talk) 13:20, 17 September 2012 (UTC)

Megaviridae?
So far Megaviruses have not been clasified into a new family, but includend in the Mimiviridae. On the contrary, Marseilleviridae family has been already suggested and requested to the ICTV.

basics
Well I'm still not much wiser .. What actually IS a Nucleocytoplasmic large DNA virus ? Virus implies no nucleus. Right ?

Nucleocytoplasmic ? — Preceding unsigned comment added by 31.104.161.253 (talk) 18:14, 7 April 2013 (UTC)

This article is tough for a layman to understand. I came looking for a simple definition of giant viruses (what makes them giant? Are they actually large in size or does giant describe a feature of their biology?) following the discovery of one in the news. An introduction would be helpful. — Preceding unsigned comment added by 97.120.74.235 (talk) 15:54, 5 March 2014 (UTC)

Would like to join the three comments above: article neither answers the "What actually is ...?" question nor the question "What makes them giant?"(A-Amos (talk) 11:51, 6 March 2014 (UTC))

I'm not an expert, and not specialized in virology - just a second year bio student. But the way I interpreted this, together with a few other ambiguous stubs, is that "nucleocytoplasmic" refers to the virus infecting the host's nucleoplasm and/or cytoplasm. As for "giant", some other articles cited physical diameters of some of these viruses, including some of the largest known viruses. They've shown up under light microscopes (viruses are usually way too small to see with light) and been mistaken for bacteria (which are normally much bigger than viruses). Giant could also refer to genome size, which in viruses tends to correlate with overall physical size. — Preceding unsigned comment added by 142.113.151.219 (talk) 11:51, 10 March 2016 (UTC)

Giant viruses
Giant viruses redirects here. If "Giant virus" is equivalent to a clade name (not merely a informal descriptor), the term should be defined in the lead, and/or clarified/distinguished from usage in Girus. --Animalparty-- (talk) 18:13, 10 March 2014 (UTC)
 * As someone who has no real knowledge in that area I would enjoy reading more about what qualifies these as "large." PurpleChez (talk) 20:16, 13 March 2014 (UTC)

I too have no real knowledge on the subject - but it does appear that these two pages are about the same subject and therefore should be merged. --Adeade00 (talk) 17:44, 21 February 2016 (UTC)

I second Adeade's motion, but lack the expertise to merge the articles. — Preceding unsigned comment added by 142.113.151.219 (talk) 11:53, 10 March 2016 (UTC)


 * Girus should redirect here. It is a synonym to "giant virus". It's not a clade name but an informal subset of the NCLDVs. The definition varies, mostly "> 300 kb", "> 500 kb" in the paper

 * which I used to update Nucleocytoplasmic large DNA viruses. --Rainald62 (talk) 12:24, 3 April 2016 (UTC)

Is this a clade or a grade?
Is this just big viruses that are not related phylogenetically? --Nessie (talk) 03:04, 18 September 2019 (UTC)
