Jakra worm

From Tardis Wiki, the free Doctor Who reference

Jakra worms were large, dangerous predators from the Briss Constellation. They were eight feet long and looked like hairy sharks.

The Doctor helped Kamalnayan Bajaj deal with an infestation of Jakra worms. In return, Kam allowed the Doctor to eat free in his restaurant at any time. (PROSE: Ghosts of India)
