Ogros
From Tardis Wiki, the free Doctor Who reference
Ogros is a swampy planet in Tau Ceti. Ogros' swamps are filled with amino acids and proteins, which the native silicon-based Ogri absorb for food. The Doctor has a very low opinion of Ogros.
Cessair took three Ogri from Ogros, which contravened Article 7594 of the Galactic Charter. They were returned after sentence was passed upon her. (DW: The Stones of Blood)
