"Little shark" is a children's song about shark family. Since 2016, it has been popular as a bonfire song and spread through social media, online video and radio.

"Little shark" originated from bonfire songs or hymns. Some sources refer to traditional myths as the basis, while others originated in the early 20th century, which some believe may have been developed by training camp consultants inspired by the movie "jaws.". It became a bonfire song and each member of the shark family introduced it with different gestures. Different versions of the song have sharks hunting fish, eating sailors or killing people, and then these people go to heaven.

Various entities own the copyright of the original video and recording of songs, and some own trademark goods according to their versions; however, the underlying songs and roles are believed to belong to the public domain.

The dance version of "little shark" was popular online in the 2007 YouTube video "little sea shark" (in German, "Kleiner Hai") and released by Alexandra m ü ller, whose stage name is alemuil. With the theme of "great white shark", this version tells the story of a shark growing up and able to swim. The video quickly became popular, and EMI records provided alemuel with records and released songs with disco beats on May 30, 2008. Singles ranked 25th in Germany and 21st in Austria. The YouTube community produced pop music videos based on singles and raw videos. The German version of the song is still popular among German youth groups and has been released in a variety of variants (also in different German sayings).
