Ogron eater

From TARDIS Index File, the free Doctor Who reference.

Ogron eaters were large orange blob-like creatures native to the Ogrons' home world. They preyed upon Ogrons, yet they worshiped it reverently.

During a Human/Draconian expedition to the planet, the Doctor saw one of the creatures eat one of the Ogrons that were attacking them. (DW: Frontier in Space)
