* FanNickname: A number were given to the main cast [[http://squick-too-quick.tumblr.com/post/44725923400 by the growing fanbase]] a while before the anime was announced and character personalities established, including:
** "Tsun" for Haruka, though he turned out to be genuinely more of a [[SugarAndIcePersonality Kuudere]].
** "Senpai" or "Sweetie-pie" for Makoto, emphasizing his caring nature.
** "Shota" for Nagisa, who has the typical Token (Male) Mini Moe physical aesthetic, if not as exaggerated as [[OuranHighSchoolHostClub some]]; he's more or less a {{CloudCuckoolander}}, though.
** "Pimp" [[labelnote:Explanation]]Appeared to be waving to the fans, presumably girls, in the original commercial, and thus identified as a ladies' man.[[/labelnote]] or "Cameron"[[labelnote:Explanation]] Stands for '''came'''-here-for-the-girls-turned-gay[[/labelnote]] for Rin.
** "Megane" or "Glasses" for Rei when he was first revealed and most were still more comfortable using the nicknames because the anime still had not aired.
** "Far Left-kun" or "Far Left-kun 2.0" for Seijuurou due to his resemblance to Rei's prototype design.
*** The nickname has also migrated over to Momotarou.
** The series itself is nicknamed "Swimbros!" or "Gay Swimming Anime."
*** Hilariously enough, if you simply put "free" into Google images, you get pictures of a red button with the word "free" written on it, but if you put in "gay swimming anime" pictures from the show come up, along with the anime {{Tsuritama}}.
*** {{Tsuritama}} is sometimes [[FanNickname referred to as]] 'The Gay Fishing Anime', so this makes sense.
** "Anime {{Music/Macklemore}}" for Goro, due to their similar look.
** "Minishiba" for Momotarou, due to being Seijuuro's younger brother
* The symbolic equation of Haruka=dolphin and Rin=shark is already established (promo art, Rin's teeth); and in the endtheme animation, as Haruka wanders through a desert wasteland, what does he pass the skeleton of? A Chinese river dolphin.
** Dolphins and sharks don't exactly get on well in the animal kingdom. Then there's Makoto's orca...
* RelationshipVoiceActor: Siblings [[Creator/AkenoWatanabe Gou]] and [[Creator/MamoruMiyano Rin]] worked in the past as partners as [[Manga/SoulEater Death the Kid and Liz Thompson]].
* WhatCouldHaveBeen: [[http://i0.wp.com/livedoor.blogimg.jp/otaku_blog/imgs/1/6/16d7adcc.jpg This image]] shows the Iwatobi Swim Club without Rei, but instead with another character named Kaede. Apparently this character would have been more easygoing than Rei, as well as retaining the "inexperienced newcomer" role Rei eventually got according to [[http://ultimatemegax.wordpress.com/2013/09/01/free-guidebook-interview-hiroko-utsumi-x-futoshi-nishiya-part-1/ this interview]].
