"Tarantula" / "Fasten Your Seatbelt" is the fourth single by Australian drum and bass band Pendulum. It was released on 27 June 2005 by independent label Breakbeat Kaos, and was their second release with the label. While "Fasten Your Seatbelt" features production from The Freestylers, "Tarantula" features production from Fresh and vocals from $pyda, together with Tenor Fly from The Freestylers. It peaked number 60 on the UK Singles chart. Both songs were included on the CD release of Hold Your Colour a month later. "Fasten Your Seatbeat" samples a line from Spider-Man 2 where Dr. Otto Octavius (Doc Ock) is firing up the fusion reactor for the first time ("Ladies and gentlemen, fasten your seatbelts.").
