unclear display skeleton remark
'The Natural History Museum in London contains a famous mounted skeleton and life-size model of a blue whale, which were both the first of their kind in the world, but have since been replicated at the University of California, Santa Cruz.'

'Replicated'? As in, the skeleton is a replica, or the UCa got their own skeleton? —Preceding unsigned comment added by 193.60.94.9 (talk) 18:26, 21 January 2011 (UTC)

It is not correct that first mounted skeleton was in London. The first mounted skeleton of blue whale (27 m) is on the display of Zoological museum in Saint-Petersburg (Russia) since 1901 (In British Museum from 1932).

The myth of being able to swim through a blue whale's arteries
This idea is put around as a fun anecdote to really impress on us just how large the blue whale is and has even been eminem recently repeated by the likes of Sir David Attenborough but is, to the best of my knowledge, totally untrue. Apparently even their largest arteries measure "only" 7-9 inches across; huge, to be sure, but not large enough to swim through.

I take it that the contributors to this article are aware of the falsity of this "fact" as it's not included in the article but does anyone agree it might be a good idea to mention this myth somewhere in the article to educate people that it is in fact untrue?

Blue whale is the largest animal ever to have lived, bigger than any dinosaur. Recent studies show Megalodon only grew to 20 meters. 61.230.79.242 04:06, 24 June 2006 (UTC)

Yeah, Megalodon was big but nowhere near as big. 213.78.183.91 (talk) 10:50, 22 February 2008 (UTC)

There was a dinosaur starting with b that was bigger; the low estimate is 200000 kg. See dinosaur size, it's in the "most massive sauropod section. 122.105.217.138 (talk) 02:26, 23 April 2008 (UTC)

"Largest living animal"-> I think largest extant animal would be better, as this sort of implies that there's only one of them. —Preceding unsigned comment added by 62.31.164.49 (talk) 15:17, 9 January 2009 (UTC)

I'm pretty sure this claim was made when Brachiosaurus was thought to be the biggest dinosaur. Several sauropod dinosaurs were slightly larger. Amphicoelias, a relative of Diplodocus, was nearly 200 feet long, nearly twice as long as a blue whale. But at 200 tons, the Blue Whale may be the heaviest animal ever.

It's impossible to say that it's the "largest animal ever to have lived." There are sauropod remains that could, if verified, belong to larger animals (one example: []), so I agree that "largest living animal" would be more accurate. In fact, without starting a cryptozoologial discussion, given that so little of the ocean has been explored, I would even go so far as to say that the blue whale is the "largest living animal known." HeadVI (talk) 20:28, 6 July 2009 (UTC)

I agree with the above comment. The current wording: "At up to 32.9 metres (108 ft)in length and 172 metric tons (190 short tons)[4] or more in weight, it is the largest animal ever known to have existed." is NOT supported by the reference provided (a very low-quality source, too). Interlope (talk) 00:42, 12 September 2009 (UTC)


 * The Blue Whale is listed at 172 metric tons, with the largest at over 190 tons 1. While the Amphicoelias sauropod is listed as 'only' 122 metric tons. And the estimate of 220 tons for the Bruhathkayosaurus has been reported as inaccurate, with a revised estimate at up to 139 tons. It can be said that "The Blue Whale is the largest animal ever to have lived", knowing that this could be revised in the future. We should not avoid this phrase just because a sauropod "could, if verified" be a larger animal.  Until it is verified, the Blue Whale is the largest animal that ever lived. CuriousEric (talk) 04:21, 12 September 2009 (UTC)


 * The suppossed length of Amphicoelias sounds more like an anecdote or missmeasurement. Isn't it very convinient that the original 20th centurie fossil was destroyed?--195.130.92.43 (talk) 10:19, 22 October 2009 (UTC)

Tons
The article talks repeatedly about tons. What kind of tons? AxelBoldt 16:30, 29 Sep 2003 (UTC)


 * Who cares? They are all the same size, near enough. Imperial or metric, it doesn't matter. 1000 kg or 2240 lbs - we are taliking about differences too small to measure in this context. Tannin 21:51, 29 Sep 2003 (UTC)


 * I care. In the US, the most common ton is 2000 lbs, not 2240. It makes a difference if NMML estimates the biggest whales to be about 1.8 x 105 kg or 2.0 x 105 kg. AxelBoldt 02:41, 30 Sep 2003 (UTC)


 * A trickier question that you might think. Most of the BWs that have been weighed were weighed by whalers (i.e. not scientists) in the 1930s and before. Standards were erratic. E.g. page 23 of Calambokidis and Steiger's book Blue Whales says
 * Maximum weights have been reported to be about 160-190 tons; there was also some confusion because 'tons' referred to three slightly different units
 * Most books on the matter appear to be authoritative, but hard data is hard to find, so some circumspection should be taken with any weights you read. Having said all that, virtually all references I have access to are written in metric tons (i.e. 1 ton = 1000kg), and this article (or at least the parts I wrote) can be taken to be a 'conservative average' of the book references and so is in metric tons too. Pete 22:57, 29 Sep 2003 (UTC)


 * Does this apply to the NMML estimates as well? AxelBoldt 02:41, 30 Sep 2003 (UTC)
 * Will check on that. Pete 06:12, 30 Sep 2003 (UTC)
 * Sorry never did manage to find that out. Pete 09:56, 14 Nov

It may be the largest animal in the fossil record but I disagree that it was the biggest animal ever – bit daft...the earth has been around for a very long time (approx 4.5 billion years) and the fossil record has been sparse in representation of the earth’s biological history (e.g. the "human" record within the last 145 000 years is sparse – let alone life forms that existed millions and hundreds of million years ago.) I would like my opinion to be considered in lieu of, what I feel, is a gross assumption. —Preceding unsigned comment added by Greghoets (talk • contribs) 09:57, 21 April 2009 (UTC)

Range Map
Range map - this is a little inaccurate: the North Sea and Baltic Sea should not be coloured, as the species is no more than a highly exceptional vagrant in these shallow waters. I'd suggest an edge to the range roughly from Orkney or Shetland across to Bergen. Can someone do an edit? (I don't know how to edit the maps!) - MPF 23:57, 23 Feb 2004 (UTC)
 * Fixed. You can edit the map by dowloading it, editing it however you can in your favourite paint/photo editting program and re-uploading it with the same name - if you do this please re-add in your upload summary any description/copyright notices that were there previously. Pete/Pcb21 (talk) 00:14, 24 Feb 2004 (UTC)
 * Thanks! Should've mentioned they're also not in the Irish Sea, I'll do that as a trial tomorrow to see if I can edit it successfully - MPF 18:39, 1 Mar 2004 (UTC)
 * My maps were effectively the intersection of two book sources. They included both the Irish and Baltic areas. I agree with you the chances of seeing a Blue there are virtually nil... yet the guides I took my inspiration from include it all.... what do you think is going on? Pete/Pcb21 (talk) 20:44, 1 Mar 2004 (UTC)
 * Hi Pete, No idea! But they certainly avoid shallow seas, I gather because of the higher predation risks by Killer Whales (which they escape by being able to dive deeper than Killers can). Maybe the guides map all known records, vagrants included? .... I produced a new map (basically showing the 200m submarine contour & shallower worldwide, as white), but when I uploaded it, it came up all black, so no idea what's happening there. Fortunately (despite not changing the file name) it hasn't overwritten the old map (I hope!!). - MPF 00:18, 3 Mar 2004 (UTC)


 * Finally got round to doing a new map. It is not based on hard data, just on marking as white the world's shallow inshore waters that Blue Whales (as far as I know) don't visit other than as vagrants. I'm sure it is not accurate, but I do think it is better than the current map. Please feel free to edit it for any improvements, and add to the main article if you think worthwhile - MPF 00:14, 21 Nov 2004 (UTC)


 * I won't object to you making the change if you want to make it. However as you're aware all 80-odd range maps for the cetaceans (best accessed through Category:Cetaceans) all use the same lax standard for range inclusion (i.e. include vagrants) because they all come from the same two sources. If there is way/enthusiasm for a) redefining the inclusion standard in a specific way (the current inclusion standard is "it says so in these two books" and b) applying this standard across all articles then my support would be whole-hearted. At the moment I am torn between wanting to provide useful information on this page and consistency across all pages, the usual conundrum! THanks for your work, MPF. Pcb21| Pete 09:52, 21 Nov 2004 (UTC)

Beaching
Grutness noted on the FAC page that there have been at least some incidents of beached Blue Whales.

In particular there was one on the Isle of Lewis in Scotland in 1920 - see http://www.isle-of-lewis.com/things_to_do/places-to-visit.htm - but this is a special case. The whale in question had an unexploded harpoon in its head, and probably wasn't thinking straight. In general, I believe beached Blue Whales are extremely rare because Blue Whales never really go close to shore - they are so big they stay well away. When I have found some data on this I will add it to the article. Pcb21| Pete 11:42, 17 May 2005 (UTC)


 * The fact that they don't beach cause they never really come close to shore is pretty interesting, something about them staying in deep water could go in the distribution section. --nixie 14:18, 19 May 2005 (UTC)

Average
Could we put an arithmetic mean for the length? I've 105 feet (something like 30 meters) was average. Any confirmation? Cameron Nedland 14:33, 2 January 2006 (UTC)


 * I've seen an average of 26 m (85 ft) and 120 t (132 sh t) for females, and 25 m (82 ft) and 90 t (99 sh t) for males – or similar figures – in several books.

I have found more information on ("Blue Whales")and ("Whale Watching").

The three major whaling nations (Norway, Japan and Iceland) have large and growing whale watching industries. Indeed Iceland had the fastest-growing whale watching industry in the world between 1994 and 1998.. January 2010. Many conservationists argue that a whale is worth more alive and watched than dead. The goal is to persuade their governments to curtail whaling activities. This debate continues at the International Whaling Commission, particularly since whaling countries complain that the scarcity of whale meat and other products has increased their value. However, the whale meat market has collapsed, and in Japan the government subsidizes the market through distribution in schools and other promotion. In 1997 2,000 tonnes of whale meat were sold for $30m - a 10 tonne Minke Whale would thus have been worth $150,000. There is no agreement as to how to value a single animal, though it is probably much higher. However, it is clear from most coastal communities that are involved in whale watching that profits can be made and are more horizontally distributed throughout the community than if the animals were killed by a whaling industry. Upon the resumption of whaling in Iceland in August 2003, pro-whaling groups, such as fishermen who argue that increased stocks of whales deplete fish populations, suggested that sustainable whaling and whale watching could live side-by-side. Whale watching lobbyists, such as Húsavík Whale Museum curator Asbjorn Bjorgvinsson, counter that the most inquistive whales, which approach boats very closely and provide much of the entertainment on whale-watching trips, will be the first to be taken. Pro-whaling organisations such as the High North Alliance on the other hand, claim that whale watching is not profitable and that some whale-watching companies in Iceland are surviving only because they receive funding from anti-whaling organizations.[12]

The page should be updated to reflect the latest estimate of abundance for the Antarctic population (and subspecies B.m. intermedia) which is 2,280 (95% CI 1,160-4,500). This requires editing of an earlier section also which says the largest population is in the north Pacific numbering about 2,000. Obviously the Antarctic population is now about the same size or perhaps a little larger. Source: Branch, T. A. 2008.

Antarctic At one time the most abundant in the world and probably containing 90% of the world's total numbers, now increasing at 2.4-8.4% per year (median 6.4%) Branch 2008a. Current numbers were 2,280 in 1997 (Branch 2008b). Original numbers were 235,000 to 307,000 (best estimate 256,000) (Branch 2008a). Current population is possibly the most depleted of any large whale population, at less than 1% of pristine levels (Branch 2008a).

PYGMY (Indian Ocean/Australia/New Zealand) Survey: 424 off small area of Madagascar (Best etal 2003). Survey: 671 off small area S of Australia (Kato et al. 2007) Total abundance likely to be high, perhaps 4000 to 10,000 Total catches: 13,022 (Branch et al. 2008) Unknown rate of change over time. If max rate of increase assumed to be 0-8% then original population 10,000-20,000 Obviously this is very uncertain

North Atlantic NA surveys 1100-1900 abundance (Pike et al. 2004), say 2000-3000 total. Increase rate 5.2% per year off Iceland (Sigurjonsson & Gunnlaugson 1990) Total catches: 10,442 Original population perhaps 6000-13000 (assuming ROI 0-8%)

North Pacific Eastern population 2000-3000 (Calambokidis et al. 2004) total oceanwide 3000-4000? Rate of change not clear, could be increasing or decreasing. Total catches: 7973 Original abundance perhaps 4000-11000 (assuming ROI 0-8%)

South-east Pacific Chile 452 survey estimate (Branch etal 2007) but this is not reliable, nonrandom survey. Likely 1000-2000 total. Unknown rate of change Catches: 5383 Original abundance 3000-7000 (assuming 0-8% ROI).

Worldwide Total current abundance 11,000 to 24,000 (better rounded to 10,000 to 25,000). Global rate of change: ranging from unknown to increasing at 6.4% per annum, most likely in the 5% range. Pre-exploitation abundance: 258000-358000 (rounded to 260,000-360,000) Depletion: Likely 3-9% of worldwide pre-exploitation levels.

 * 2) Its "Physical description" section does not have a single image to illustrate it.
 * 3) The list of reasons in "Vocalizations" could be expanded.
 * 4) The redlinks in the "Feeding" section need to be removed, modified, or created.
 * 5) There are issues with being well written: 1) the second paragraph in the lead has comma errors and awkwardness 2) the second paragraph in "Size" has choppy sentences.

I have not had anything to do with this article until a few days ago but I will try to contribute where I can. --maclean 25 06:52, 21 April 2006 (UTC)


 * I will also work with you KoH to improve this article. However I hope you don't mind if I say that your tone comes across as bullying and even hectoring. We are all volunteers here and all want to see improved articles. A more pleasant attitude from you would be helpful in avoiding a "them-and-us" feeling. But anyway onto the changes I have made:


 * Re 1) I have retro-fitted the article into the now-preferred inline citation format, and think it works a lot better now.
 * Re 2) I have added several images from Wikimedia Commons. Thank you for the suggestion.
 * Re 3) Are you saying the we should add more reasons? That list of reasons was taken from a premier paper on the topic. Why is it incomplete?
 * Re 4) Sorry if I haven't been following FAC criteria changes closely enough, but I understand a few redlinks in an article are not a problem. De-linking those species is not a good idea.
 * Re 5) I have reworded, but only slightly, the two paragraphs you specified in particular. However I disagree that the second paragraph in "size" is problematic. Contrarily, I believe the "machine-gun" writing style actually works well for the topic in hand.


 * Thus as you can see I have taken all the points you raised and made several improvements. The ball is now back in your court :). Pcb21 Pete 23:01, 21 April 2006 (UTC)

Blue whale taxonomy
Genetics reveal that that the four types od blue whales are distinct. The northern form should be Balaenoptera musculus, the southern form B. intermedia, the pygmy form B. brevicauda, and the nothern Indian Ocean form B. indica. —Preceding unsigned comment added by 72.194.116.63 (talk • contribs)
 * Do you have the source (scientific article)? KimvdLinde 23:13, 1 May 2006 (UTC)

A recent genetics paper finds evidence for B.m. intermedia and B.m. brevicauda but no evidence for a separate subspecies B.m. indica, although the sample sizes were very small. Additionally, South-east Pacific blue whales (Chile) were found to be as different from B.m.brevicauda as from B.m.intermedia and should be treated separately. B.m.musculus was not examined in the study.

Vocalizations
The text makes a comparison between the blue whale's 188dB re 1 uPa at 1m production, and a jack hammer that measured 100 dB at 2m, and i assume re 20 uPa which is common for in-air. I think this is misleading and that the jack hammer should be removed. Direct comparisons of between in-air and underwater levels are difficult anyway (taking into account directivity and frequencies). Additionally, the sperm whale can produce up to 230dB for its sonar when it's measured on-axis, making it 'louder' than the blue whale.Vencedor 16:58, 26 February 2007 (UTC)

Pistol Shrimp
The Animal Planet program "The Most Extreme" claims that the Pistol shrimp can produce a sound with its claw that is louder than a whale's call, and the Wiki entry backs this up (200 vs. 188 decibels). PenguinJockey 01:07, 10 March 2007 (UTC)

Underwater Picture
Is there a picture that exists on the Wikipedia database somewhere that shows a blue whale under the water? I think that would be a much better picture to put at the top of the article, rather than a couple of drawings. Just my opinion. Mientkiewicz5508 20:26, 27 March 2007 (UTC)


 * I agree. The picture at the top of the article is washed out and difficult to recognize, and I think one of a blue whale under the water would better represent the article. There must be better pictures out there. Sorry if I responded wrong, I'm new. Gibberish517 20:15, 6 August 2007 (UTC)

massive vs largest
there are strong distinctions between the terms "heavy," "massive," and "large." It seems to me that, per volume, the blue whale may not be the largest animal known, but it probably is the most massive ("heavy" implies the force of gravity, rather than specifically mass; of course, NASA trains in water because it is close to "weightless," meaning one could legitimately claim that the blue whale is nominally weightless). Given that it has relatively small dimensions compared to its clearly gargantuan mass, it might be fun to speculate about the "most dense animal that ever lived," but that's kind of tangential. I'd have changed the simple word in the leading paragraph from "largest" to "most massive," but of course, the page is protected, preventing such clear vandalism. 69.143.136.139 02:52, 27 July 2007 (UTC)
 * According to Largest organism (I really should check a reliable source, but I'm too lazy right now), the blue whale is largest by both volume and mass. Has anyone heard differently? Unfortunately many of our articles about whales get vandalized a lot, so there are weeks at a stretch when the article is semi-protected. You can edit these pages (and please do!) if you have an account that is more than four days old. Cheers, Kla’quot (talk | contribs) 06:10, 28 July 2007 (UTC)

I don't have an account, but I just wanted to mention that the conversion from metres to feet under the Life section is wrong for the males. 20m is equal to 66ft, not 70ft.

Authochthony writes: - surely 20 metres is an estimate - not "exactly half-way between 19.9(999) metres and 20.(000)1 metres"; and surely 20 metres is [a bit] nearer '70 feet' than '60 feet' [I might have estimated/used '65 feet'. but I didn't know enough to add the bit quoted.] Incidentally, unless soemthing is an exact measurement (like, say, Bob Beamon's 1968 long (=broad) jump of 8.90 metres, 29 feet, two and a half inches) - surely it is better to use a similarly rounded figure for the conversion into whichever unit(s) your estimate is not in. Tons, tonnes, and (short) tons - of 2240, ~2205, and 2000 pounds each, respectively, is a case in point; about three tons [hey - whatever!] - but about 200 tons/tonnes [225 (short) tons) - and 25,000 tons/25400 tonnes/27500 (short) tons is surely reasonable.

Do Blue whales breach?
The Whale surfacing behaviour page lists Blue whales as one of the species that exhibit breaching behavior, but there is no reference there and no mention of it here.

“It is rarely that the Sulfurbottom [blue whale] 'bolts' or 'breaches,' yet, when engaged in this sprightly act, the animal presents itself in that degree of magnificence which is commensurate with its inordinate activity and immense proportions.” Charles Melville Scammon, The Marine Mammals of the Northwestern Coast of North America, 1874, p. 72. The term "sulfurbottom" was the name Yankee whalemen gave to the blue whale. Supposedly it had to do with the yellowish sheen created by diatoms on its ventral surface. I believe it is caused by diatoms, but I may have erred on the species. It’s been a while since I’ve read about this particular topic. Jonas Poole (talk) 23:28, 29 February 2008 (UTC)

 * If information on these additional taxa is to be added, it would be better explained in the "Taxonomy" section, along with suitable references of course. If you can suggest such an addition with appropriate reliable sources, then please do so, and use another.

Incorrect current abundance of Antarctic blue whales
Right now it states: "Recent abundance estimates for the Antarctic subspecies range from 1100[51] to 1700.[10]" These estimates come from an incomplete set of circumpolar surveys that have now been completed. The estimate from the complete set of surveys is 2280 Antarctic blue whales, which should replace the existing text. The source reference is a published paper:

Branch, T. A. 2007. Abundance of Antarctic blue whales south of 60°S from three complete circumpolar sets of surveys. Journal of Cetacean Research and Management 9:87-96.

I am the author of both the original estimates (1100, 1700) and the most recent estimate (2280). I have previously posted this correction but no action was taken.

Edit request from Dexterford, 15 September 2010
Add to "Whale Watching" section:

Blue whales are increasingly seen off Southern California. There is a consistent summer population (July-September), estimated at 2000-plus, that converges between the Channel Islands of Santa Rosa, San Miguel and Santa Cruz and the city of Santa Barbara. There have been summer blue whale whale-watching cruises run out of Santa Barbara on commercial boat The Condor for at least the last 14 years, with a high success rate of encountering blue whales.

The Voyager, out of Redondo Beach, also runs blue whale whale watching tours during the summer months. And a small but consistent population of 5-10 blues also lingers between the Palos Verdes Peninsula and Catalina Island in the summers, which can be accessed via the Voyager or by private boat. There are also whale-watching boats out of San Pedro and Long Beach that frequently encounter blue whales during the summer.

A population of 20-to-50 blue whales was been seen off Redondo Beach in early September, 2010. Stand-up paddle boarders, kayakers and other small-boat sailors encountered the Southern California/Northern Pacific blue whales from shore to about 4 miles offshore, feeding on large quantities of krill near the surface.

Museums section
I would propose some new language for the front of this section:

The Smithsonian Institution created the first full cast of a blue whale in 1903. It was first displayed at the Louisiana Purchase Exposition and then subsequently at the National Museum of Natural History, where it remained until around 1960, when it was replaced by a new, even bigger blue whale model. This blue whale, a museum favorite, remained on exhibit until 2000. (Today the museum exhibits a model of a right whale rather than a blue whale.)

For the sentence about the London model, I would propose the following edit:

The Natural History Museum in London contains a famous mounted skeleton and life-size model of a blue whale, which were both the first of their kind in the world, but have since been replicated at the University of California, Santa Cruz and elsewhere.

e.g. B. m. musculus, the northern blue whale consisting of the North Atlantic and North Pacific populations; B. m. intermedia, the southern blue whale of the Southern Ocean; B. m. brevicauda, the pygmy blue whale found in the Indian Ocean and South Pacific; and the more problematic B. m. indica, the great Indian rorqual, which is also found in the Indian Ocean and, although described earlier, may be the same subspecies as B. m. brevicauda.198.232.211.130 (talk) 23:03, 15 June 2011 (UTC)

Size - paragraph 3
"The longest whales ever recorded were two females measuring 33.6–33.3 metres (110–109 ft) respectively."

When two amounts are listed, they should be separated by a comma, not a hyphen. A hyphen should be used when there is a range (several samples).

Also, "repectively" should be used when two sets of data correspond to each other. It should also have a comma before it. e.g. Alice and Betty weigh 40 and 44 kg, respectively.

I propose the sentence be revised to, "The longest whales ever recorded were two females measuring 33.3 and 33.6 metres (109 and 110 ft)." 198.232.211.130 (talk) 23:12, 15 June 2011 (UTC)

Edit request from Tincanmansiimon, 16 August 2011
i have a knowledge on how blue whales feed and so interesting facts like the technic on the way they feed and why reserch about 10 miles off sri lanka is being done

if thats not what i was supposed to write heres another please add to the end of the feeding section some blue whales have been sighted near sri lanka diving to get deeep krill eg if there is some school of krill at -500m the whale will go down -550m and swoop up into the school open its mouth and then fliter out the water with its keratin and keep doing so

please accept this request and i will try to improve the page to my full extent

Conservation
The Blue whale is listed on Appendix I of the Convention on the Conservation of Migratory Species of Wild Animals (CMS) as this species has been categorized as being in danger of extinction throughout all or a significant proportion of their range and CMS Parties strive towards strictly protecting these animals, conserving or restoring the places where they live, mitigating obstacles to migration and controlling other factors that might endanger them. In addition, Spinner dolphin is covered by Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MOU). — Preceding unsigned comment added by Water manager (talk • contribs) 10:39, 31 August 2011 (UTC)

Edit request for Sleeknub related to migratory patterns
In the "Population and Whaling" section under the heading "Threats other than hunting" the article currently says: "The whales summer in the cool, high latitudes, where they feed in krill-abundant waters; they winter in warmer, low latitudes, where they mate and give birth."

I suggest adding to the end: "However, although other baleen whales follow this basic pattern, scientists no longer agree that blue whales do.  Evidence is mounting that the whales in fact remain in feeding grounds year-round."

Thanks.

 * A single instance of blue whales being sighted off the Washington coast in late fall (which early December is) shouldn't result in such an edit being made. Some blues, like fins and minkes, may remain in northern feeding grounds year-round, but the fact is many still migrate south to Baja and Costa Rica to breed (at least in the eastern North Pacific). Heck, some stay year-round off Baja feeding. They might not follow the "basic pattern" you mentioned above, but they certainly don't all follow the simplistic pattern you've proposed either. With that said, I see no point in any revisions being made. SaberToothedWhale (talk) 00:04, 21 December 2011 (UTC)
