Star Serpent
From Tardis Wiki, the free Doctor Who reference
Star Serpents were found in cold empty spacelands between distant galaxies. They usually ate nothing but stray neutrinos floating in the vacuum. "Serpent" was misleading as these giant space worms appeared to have had very basic living functions.
One swallowed the Doctor's TARDIS with the Eleventh Doctor, Amy Pond and Rory Williams still aboard. (COMIC: The Star Serpent)
