Tritovores are a spacefaring species of sapient insectoid humanoids known to inhabit (or at least travel through) the Scorpion Nebula, located in the other side of the Universe from Earth. They are coprophagous beings, feeding on the excrements of other species, and often establish commerce with largely populated planets which are more than willing to sell their wastes to someone.
Tritovores appear somewhat like humanoid flies, with complex mouthparts and enormous compound eyes. Their hands each sports three large fingers. Their technology notably includes anti-gravity devices, telepathic translators which only work one way (that is: Tritovores can understand alien speech but not vice-versa), and a type of metal called photavine steel, which when heated on the outside actually cools down the temperature in the inside.
- The Doctor is able to understand the Tritovore language, likely due to his telepathic abilities. The fact that his companions in "Planet of the Dead" had never been in contact with the TARDIS up to that point (meaning they didn't benefit from the translator circuits) probably accounts for why they and the audience are not able to understand the Tritovores.
- A Tritovore picture is seen representing one of the victims of the Minotaur in "The God Complex"; along with several other species like Humans, Silurians, Sontarans, Catkind, Judoon and Hoix.
