Verticulan spider were spider-like creatures that resembled jack-o'-lanterns. They were native to the planet Verticulus. They had three eyes and six legs.
When the Eleventh Doctor and Amy Pond visited Verticulus to experience a Verticulan Halloween, the Doctor's TARDIS materialised near four spiders, one of which had long legs. (COMIC: Wholloween)
