This Boto needs a Photo.... anyone live in/been on holiday to the Amazon??? Pete/Pcb21 (talk) 09:26, 27 Feb 2004 (UTC)

Hello, I've removed the photo posted by Identity (Photo1b.jpg) , because that's not a Boto pic (Inia geoffrensis), but of a Delphinidae species. Cheers. Exlibris 21:59, 1 December 2005 (UTC)

tool use

They're also one of the few animal species thought to use objects for sexual display. The males pick up objects and strut around with them during mating season to attract females. This according to Dr. Tony Martin of the Sea Mammal Research Unit at the University of St. Andrews in Scotland.

page cleanup Dec. 10, 2008

I have temporarily reverted to the revisions of Kspencer3. Kspencer3 added a lot of new information, however, also in the process removed correct scientific notation, Wikipedia hyperlinks, correct reference links, added inappropriate links etc. etc. Once I fix this, I will upload the corrected and verified version of this article by Kspencer3.

LET'S LIST EVERY NAME THIS ANIMAL HAS IN EVERY LANGUAGE

we'll learn so much about this species if every possible nomenclature from ever language was mentioned. —Preceding unsigned comment added by 68.175.90.74 (talk) 12:34, 4 September 2009 (UTC)

Cleanup

This article doesn't flow very well, especially the lead paragraph. Someone have some time to clean it up? Bob the WikipediaN ^{(talk • contribs)} 17:41, 1 September 2011 (UTC) It also contradicts other articles on cetaceans by stating only these river dolphins have males larger than females whereas general article indicates the this occurs in other toothed whales. This article also suggests pinkness is due to scarring in males in one sentence but due to environmental factors on another

Pink dolphin

I'd like an editor to address why it has pink flesh, or why it looks pink (is it because of the water?), and why the shown photograph they don't look pink. Thanks. --Kiyoweap (talk) 03:19, 25 May 2012 (UTC)

Most tropical species of cetacean (e.g. Bryde's, tucuxi, striped dolphin, etc.) can have a pinkish belly. It has something to do with flushing out excess heat. I remember hearing somewhere that boto flushed pink when aroused, but I don't know if that's true. I don't have a ref. This is all just off the top of my head.

"The pink skin is caused by blood flow through the capillaries and fades quickly after the animal dies. The pink coloration is also affected by activity and water clarity; pink Amazon River Dolphins occur mainly in turbid waters, and generally become pinker when aroused." (Reeves, Guide to Marine Mammals of the World, 2002, p. 307). SaberToothedWhale (talk) 17:57, 25 May 2012 (UTC)

In its current form, the article describes the color as "carnation pink". Well-meaning editors have assumed that the carnation pink part was just unnoticed vandalism and took that part out, but the dolphin really is pink. Adding a citation to an online source for that statement would help doubters realize that it really is pink, but I haven't found a source for it being "carnation pink". Can anybody help?

Popular Culture - Movie The Dolphin 1987

The Spanish wikipedia has links to the 1987 film Ele o Boto/ The Dolphin, which deals at length with the popular legend concerning this mammal. I am going to keep on posting similar links here, as these are highly relevant to the subject of the article. 24.244.23.53 (talk) 17:48, 25 January 2014 (UTC)

I don't know about the state of this article in the Spanish 'pedia but if you are talking about these edits, then you still need sources to establish notability. For "In popular culture" sections, according to this, you need to clearly establish first, whether the movie was indeed notable and relevant to this article--we just simply cannot add every movie on dolhpins here (example: does it have it's own article here?). Usually unsourced content is kept for a while, tagged "citation needed" and removed later if sources are still not provided, I was forced to revert because only the movie title with an external link to youtube/imdb was added.

About citing sources, read How to cite and reliable sources for help (Imdb and Youtube cannot be used normally). If you insist on adding it without a source I won't revert you again (but no external links please), remember that it's still liable to be removed by any other passing editor who cleans up this page. Sincerely, Ugog Nizdast (talk) 14:43, 26 January 2014 (UTC) pink dolphins are caused by the oxegeon in their blood vesels which allows them to control theyre oidy tempersture easier then other dolphins this would relut in the reason as to why they are pink

Taxonomy: contradiction

It says two recognized species and lists four. We need an expert or aficionado to fix this. 186.136.178.51 (talk) 16:52, 11 May 2015 (UTC)1:52PM -0300GMT Martin

Baby, the last dolphin in Europe, has died

The last river dolphin at the Duisburg zoo has now died, http://www.zoo-duisburg.de/flussdelfin-im-hohen-alter-verstorben/

Also, it seems to have gone unmentioned here but all the dolphins in Venezuela are also dead, https://globovision.com/article/las-toninas-ya-no-alegran-al-acuario-de-valencia — Preceding unsigned comment added by 51.7.177.93 (talk) 16:50, 21 December 2020 (UTC)

Boto Predation on Eel

As documented below, Botos indeed seem to hunt Eels, interestingly by slamming the eel repeatedly into the air. There seems to be no academic research on it despite the footage seen however, so should it be added into the wiki? (TL:DR; Documented doing so but no Academic Info on it)
