A huge Conger eel was filmed at a Spanish aquarium, apparently dancing to the sound of saxophone music.
The video below was taken at Aquarium Finisterrae, in La Coruna, where a band was playing outside the eel's tank. The fish can be seen swaying from side to side.
The rest of the fish appeared unimpressed by both the music and the eel's choreography skills.
The video was uploaded onto YouTube by Oscar Bouzas last Thursday, and has since been viewed thousands of times.
