"Tarantula" / "Fasten Your Seatbelt" is the fourth single by Australian drum and bass band Pendulum.

"Fasten Your Seatbelt" samples a line from Spider-Man 2 where Otto Octavius is firing up the fusion reactor for the first time ("Ladies and gentlemen, fasten your seatbelts"), as well as the sound the reactor made when it was being primed.

The song sampled a segment from the Discovery Channel series The World's Most Feared Animals.

These are the major formats and associated track listings of single releases of "Tarantula" / "Fasten Your Seatbelts".

"Tarantula" can be heard in the episode seven, series two of Skins when Effy, Tony and Pandora enter to the club followed by Sid's artistic scene.
