River dolphin

 * ... that the river dolphin is the only cetacean that can turn its head?

 * , I corrected the links in your hook so they don't go through redirects anymore. Also, some minor grammar quibbles: the wording of the hook should be either "River dolphi ns are the only cetacea ns that can turn their hea ds " or " The river dolphi n  is the only cetacea n that can turn its hea d "; I'll let you pick which one. — GrammarFascist   contribs talk 20:21, 29 October 2015 (UTC)
 * Done. Thanks for taking on this review
 * Looks great, . I'm sorry I wasn't clearer before that I was just making a comment, not starting a review; I usually try to review older nominations that have been waiting longer. But I tell you what, if this nomination still hasn't been reviewed in a week, ping me and I'll do a full review. { — GrammarFascist  contribs talk 16:59, 31 October 2015 (UTC)

 * Symbol question.svg Hook is really interesting and at 67 chars well under maximum. Promoted to GA on October 25 nominated following day/new enough. 22295 char/long enough. Neutral, no apparent copyvios. No photo. QPQ done. In-line citations missing at the end of numerous paragraphs: "Lipotoidea, has become extinct"; "Bolivian population to be a subspecies of Inia geoffrensis"; "river dolphins first ventured back into fresh water"; "classified as an oceanic dolphin (Delphinidae)". Citations for hook source do not confirm the claim, or I am missing it. This source given for this statement "Unlike other cetaceans, their neck vertebrae are not fused together," states only that this dolphin can move its head, but not that others cannot. The next source  given for this statement "This means they can turn their head without actually moving their entire body" states that manatees have limited head movement, but I do not believe manatees are cetaceans? I did find this source which indicates that most cetaceans cannot turn their heads, but it says beluga whales can turn theirs making the hook invalid.  Maybe you can do something for a hook regarding their lack of the ability to smell? That is very clear on page 497 here  “the typical olfaction was lost totally” SusunW (talk) 02:54, 2 November 2015 (UTC)

The first source you've given is the source for the hook (|this url, currently ref no. 22), and given that all river dolphins are, by convergent evolution, very similar, all river dolphins can turn their head (also if you look really closely at the skeleton of the neck you can see that it's not fused together, an animated image can be found ). The second one talks about all marine mammals including manatees and cetaceans. There are in-line citations for "Bolivian population to be a subspecies of Inia geoffrensis", and "Lipotoidea, has become extinct". They were all placed in the middle of the paragraph, so I'll move them to the end. I'll add sources to the other ones. Dunkleosteus77  (push to talk)  16:57, 2 November 2015 (UTC)
 * Thanks for the response. Cleared the citations issue. Now appears each paragraph is cited. As I stated the source confirmed river dolphins can move their heads. I have no issue with that. It does not confirm that other cetaceans cannot move their heads and the source I found stating that beluga whales can move their heads makes the claim "only" invalid. Thus, we do need a new hook. SusunW (talk) 17:33, 2 November 2015 (UTC)
 * In that case, I can put "the river dolphin is one of the only cetaceans that can move its head", thereby implying that they are one of a few cetaceans that can do so.
 * Please propose an ALT1 in the proper format ...that x? and I'll look at it. However, unless you add something that says other cetaceans cannot move their heads, I still don't think it is verified. If you add the link I cited above as #3, it clearly states most cetaceans cannot move their heads and you would be fine. SusunW (talk) 18:54, 2 November 2015 (UTC)
 * It says on the second paragraph of page 37 of this |url, the chapter title is "The Vertebrae of the Cervical Region". So, I propose the new hook should be ALT1: "... that the river dolphin is one of the only cetaceans that can move its head?"
 * That source is good, and the hook is fine now, but the source is not cited in the article. Please place the citation at the end of this sentence "Unlike other cetaceans, their neck vertebrae are not fused together, meaning they have greater flexibility than other fully aquatic marine mammals, at the expense of speed."

 * Done
 * Symbol confirmed.svg Thanks GTG on ALT1. SusunW (talk) 22:21, 2 November 2015 (UTC)
 * I'm new at DYK, what does "GTG on ALT1" mean?
 * It meant good to go on the alternate hook #1 at the bottom. You changed the initial hook, which is improper. You need to put it back as it was scratched as not acceptable and now you have 2 hooks that say the same thing. SusunW (talk) 02:16, 4 November 2015 (UTC)

 * de nada. SusunW (talk) 04:40, 4 November 2015 (UTC)

What happens next with this hook? It's been a little while and it's still in the Nomination phase, and I don't know what I'm supposed to do next. Dunkleosteus77  (push to talk)  17:49, 7 November 2015 (UTC)
 * Someone will eventually come along and promote it. It's approved, so unless a promoter substantially disagrees, it should get queued soon. SusunW (talk) 17:55, 7 November 2015 (UTC)
 * Thanks.
