Zocci

Zocci were the species to which Bannakaffalatta belonged. Zocci were small, red humanoids with spiked heads. (TV: Voyage of the Damned)

They looked similar to the Vinvocci. However, the Vinvocci pointed out that they and the Zocci were different, sounding quite annoyed when the Tenth Doctor compared them to Bannakaffalatta. (TV: The End of Time)

Behind the scenes

 * The name of Bannakaffalatta's species was never specified in Voyage of the Damned but was identified by Russell T Davies. The name was confirmed on-screen in The End of Time, by a member of a similar-looking species.
 * RTD suggested the Zocci and Vinvocci might be related species. (CON: Lords and Masters)
