Whales
do whales have hair? — Preceding unsigned comment added by 137.195.24.112 (talk) 11:48, 14 November 2006‎ (UTC)


 * No, whales don't have hair. - Mgm|(talk) 12:45, 14 November 2006 (UTC)

First off, they do have hair but it is very small and fine; all mammals have hair. Second, evolution is only a theory and I think putting it as fact is not befitting of an encyclopedia. — Preceding unsigned comment added by 72.166.222.8 (talk) 03:12, 18 December 2006‎ (UTC)
 * LOL "only a theory"? This phrase again; what a joke. Don't be a troll. - M0rphzone (talk) 01:10, 14 May 2012 (UTC)
 * Well, they do have some hair, but lambasting evolution is not a method of commenting about marine mammals. Evolution is a widely accepted theory, and this article is about making changes to the article on marine mammals, not about ones beliefs.— Ryūlóng ( 竜龍 ) 03:24, 18 December 2006 (UTC)

Evolution is a theory
Because something is widely accepted does not make it true. I was widely accepted, before Pasture, that microorganisms spontaneously generated. Evolution is a theory and should be stated as such, this is why I changed it on the page.Ssmith165 18:21, 6 April 2007 (UTC)
 * Please leave creationist trolling on Talk:Evolution— Ryūlóng ( 竜龍 ) 20:25, 6 April 2007 (UTC)
 * One who writes Pasteur as Pasture disqualifies him/herself from even coming close to a biology topic. Seriously. Arminden (talk) 08:15, 8 January 2017 (UTC)

River Otter Picture
A river otter picture is featured on this page. As far as I know river otters aren't marine mammals. If someone with more authority agrees, please remove the river otter picture and replace with a sea otter picture.
 * Very perceptive. I have replaced it with a photograph of Enhydra lutris— Ryūlóng ( 竜龍 ) 01:11, 21 April 2007 (UTC)

polar bears and blubbers
Why does it say that polar bears do not rely on blubber to stay warm? They have a thick blubber. 141.158.107.71 01:27, 25 May 2007 (UTC)Maureen
 * Their fur traps warm air. That's how they keep warm.— Ryūlóng ( 竜龍 ) 03:05, 25 May 2007 (UTC)

Aquatic mammal
Aquatic mammal redirects to this article, but this article doesn't discuss the platypus, any species of river otter, etc. I think that either this article should be renamed "aquatic mammal" and extended to cover other aquatic mammals besides just marine ones, or the redirect should be removed and a separate "aquatic mammal" article begun. What do y'all think? —Ruakh TALK 16:40, 14 February 2009 (UTC)


 * New article definitely! Marine mammals, as presented in this article, refers very specifically to cetaceans, pinnipeds, sirenians, the sea otter, marine otter and the polar bear.  These are mostly associated with saltwater with the exception of freshwater seals and dolphins.  It's a slightly ad-hocy category and definitely not taxonomic, but for historical/management reasons these organisms are grouped together as an object of study (see: http://www.marinemammalogy.org/), despite the obvious closer relationships between sea otters and river otters and polar bears and brown bears for example.  I don't believe there is a similar combined study of freshwater aquatic mammals, but there are quite a few that should at least be listed in a separate articles.  Platypus and many species of otter, of course, but also beaver, hippopotamus, nutria, muskrat, others?   I just don't know what other generalizations can be made about them.   Eliezg (talk) 21:01, 14 February 2009 (UTC)


 * I've started the article. I don't really know anything about the topic, so it's a tiny stub so far. But fortunately, we have articles on lots of aquatic and semi-aquatic mammals, so it took me less than five minutes to put together a small image gallery, at least. :-P  —Ruakh TALK 14:54, 15 February 2009 (UTC)

Wrong scope
This article is on Marine mammals; mammals that live in the ocean. Yet is also includes freshwater mammals. Marine is strictly ocean related. We already have an Aquatic mammal article. LittleJerry (talk) 17:46, 18 June 2016 (UTC)
 * Should I just move everything to the Aquatic mammal article and revert Marine mammal to the May 29 version (before I added freshwater mammals)? The Aquatic mammal article includes both freshwater and saltwater mammals. User:Dunkleosteus77 &#124;push to talk 23:51, 18 June 2016 (UTC)
 * Go ahead. LittleJerry (talk) 01:40, 19 June 2016 (UTC)
 * Wait actually, what's the point of having an article that just talks about saltwater mammals and having another one that talks about both saltwater and freshwater mammals?  User:Dunkleosteus77 &#124;push to talk 02:27, 19 June 2016 (UTC)
 * Because there are plenty of books written on marine mammals alone. Clearly marine mammals are a notable enough topic. LittleJerry (talk) 16:55, 19 June 2016 (UTC)
 * Yes, but Aquatic mammal includes both marine mammals and freshwater mammals, so it includes everything from this article and then some.  User:Dunkleosteus77 &#124;push to talk 16:58, 19 June 2016 (UTC)
 * Nothing wrong with that. The aquatic mammal article doesn't need to include two much information on marine mammals. LittleJerry (talk) 21:18, 19 June 2016 (UTC)
 * That's basically all there is though, almost all aquatic mammals are in the ocean (it's like 130 species vs 30, and 20 are shrews and otters)  User:Dunkleosteus77 &#124;push to talk 23:23, 19 June 2016 (UTC)
 * We should probably continue this to the Proposed merger discussion  User:Dunkleosteus77 &#124;push to talk 23:28, 19 June 2016 (UTC)

Some comments for the GAR
I don't have the time to review this article, but I have some suggestions to help:
 * The level of dependence on the ocean is repeated in the intro in paragraph 1 and 2
 * fixed  User:Dunkleosteus77 &#124;push to talk 16:26, 3 August 2016 (UTC)


 * They do not represent a distinct biological grouping, I think it would be clearer to say they don't represent a taxonomic or systematic group
 * fixed  User:Dunkleosteus77 &#124;push to talk 16:26, 3 August 2016 (UTC)


 * Commercial hunting lead to the extinction of Steller's sea cow I think it would be more accurate to say it was the final nail in the coffin of the species, which had declined across most of its range due to subsistance hunting
 * added  User:Dunkleosteus77 &#124;push to talk 16:26, 3 August 2016 (UTC)


 *  In contrast, both otters and the polar bear are much less adapted to aquatic living.  Sea-otters are pretty hopeless on land I think
 * they can walk on land pretty well, they just prefer not to  User:Dunkleosteus77 &#124;push to talk 16:26, 3 August 2016 (UTC)


 * The article is specifically about marine mammals but includes the boto which is not marine

Sabine's Sunbird  talk  03:32, 3 August 2016 (UTC)
 * Allow me to add that I admire anyone working on articles like this, I remember getting seabird through FA status and it's hard, so I'm just being nitpicky. Sabine's Sunbird  talk  03:35, 3 August 2016 (UTC)


 * Comment from another unaffiliated editor: I have removed pixel based sizes from thumbnails per WP:IMAGESIZE. Where displaying images larger than normal is preferable, (e.g. diagrams and maps) please use the upright factor instead. One may also want to look at MOS:IMAGELOCATION and chose to alter images to align left only when there are elements that "look" left (e.g. not the dolphin diagram). Thanks and good luck with the GAR! – Finnusertop (talk ⋅ contribs) 04:37, 3 August 2016 (UTC)
 * Actually I just included the thumb parameter and pixel based sizes to keep the caption. If I just did pixel based sizes and excluded thumb, there wouldn't be a caption. Also I put the dolphin diagram on the left because it's eye is pointing to the right. I hope it's okay if I undo your edit?  User:Dunkleosteus77 &#124;push to talk 16:26, 3 August 2016 (UTC)
 * feel free to undo it. Upright is preferable to pixel size, but it doesn't always work as desired. – Finnusertop (talk ⋅ contribs) 18:42, 3 August 2016 (UTC)


 * Perhaps in the distribution section a paragraph or even subsection on migration would be good. Whales in particular are highly migratory. Also, it might be nice to have a section on conservation (threats is important, but people are working to save them too!) Sabine's Sunbird  talk  06:00, 4 August 2016 (UTC)
 * added paragraph on migration  User:Dunkleosteus77 &#124;push to talk 18:01, 4 August 2016 (UTC)
 * added section on the Marine Mammal Protection Act of 1972 <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 18:20, 20 August 2016 (UTC)


 * Maybe we should do a joint GA review or something, it is a pretty massive article... One thing that looks off is "Mammals have returned to the water in many separate evolutionary lineages". This is too vague, many mammals have "returned to the water", but this article is specifically about marine mammals. Otherwise the list would be huge, and you would have to mention stuff like Castorocauda. Also, doesn't seem clear from the article which group of mammals were the first to return to the ocean? Also, since when has the polar bear, which is at best semi-aquatic, been considered a "marine mammal"? FunkMonk (talk) 19:58, 21 August 2016 (UTC)
 * For the polar bears, you can see why here. Also the article says " In comparison to cetaceans, sirenians, and pinnipeds, which entered the water approximately 50, 40, and 20 mya, respectively, the sea otter..." and before that it said sea otters entered the ocean 2 mya. Now that I'm writing this I realised I forgot to write about polar bears and pinnipeds... <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 20:37, 21 August 2016 (UTC)
 * Replaced "returned to the water" with "returned to the ocean" and added paragraphs on polar bear and pinniped evolution <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 21:29, 21 August 2016 (UTC)

Back to GAN
A little while back, you were reviewing the article for GA, but I went inactive and you had to close it. Well, I'm back and I think I've hit all the points that were missed back in September. Did I miss any before I renominate it? <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 00:56, 24 December 2016 (UTC)
 * It should pass easily. Chiswick Chap (talk) 06:52, 26 December 2016 (UTC)

Cladogram
The caption for the cladogram seems a bit too vague, but I can't figure out how to fix it. It currently reads "Groups in bold contain marine mammals", but if that's the case then Mammalia and Placentia should also be in bold, which seems excessive and undermines the point of bolding text. Any ideas? <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 01:38, 1 January 2017 (UTC)
 * Guess we want to say simply 'Families' really, though I see that the idea of Clades is hovering nearby. It seems well worth bolding the leaf nodes that contain (and in most cases are exclusively) MMs; having the Order Pinnipedia which is a clade of MMs bolded also seems very sensible. The visual meaning, here be whales, is clear enough, and certainly useful. Chiswick Chap (talk) 09:29, 1 January 2017 (UTC)
 * Mysticeti and Odontoceti wouldn't be bolded in that case since they're parvorders <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 16:24, 1 January 2017 (UTC)
 * I think we need to be sensible here, rather than micropicky. Chiswick Chap (talk) 16:26, 1 January 2017 (UTC)
 * Just looking for the right word here. "Families" and "taxon" would be inaccurate in this case. Maybe "orders and subordinate taxa"? <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 16:30, 1 January 2017 (UTC)
 * Makes it worse. Either relax, or we need to change it so we only have clades and leaf nodes. I'll think about it. 16:38, 1 January 2017 (UTC)
 * "Families in bold contain at least on extant marine mammal. Other taxa in bold are composed entirely of marine mammals." <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 16:40, 1 January 2017 (UTC)
 * No good. "The taxa in bold are marine." I've redrawn the tree accordingly. Chiswick Chap (talk) 16:52, 1 January 2017 (UTC)

Military Use
''The dolphins would swim up behind enemy divers and attach a buoy to their air tank, so that they would float to the surface and alert nearby Navy personnel. Sea lions would hand-cuff the enemy, and try to outmaneuver their counter-attacks.'' This seems a bit farfetched to me, especially because it might come from a self-published source. I suggest somebody looks into this just to make sure. — Preceding unsigned comment added by 68.118.175.138 (talk) 20:49, 9 June 2021 (UTC)
