Phibian



Phibians are a genetically-engineered humanoid sub-race race first mentioned in Chapterhouse: Dune. They are primitive humanoid fish creatures brought as captives to the "million planets" by the Honored Matres, much as the felinoid Futars were. They appear in Hunters of Dune.

Phibians are genetically wrought humanoids, a mingling of human and fish with a limited capacity for intelligence and vocabulary. Created out in The Scattering, they have bullet-shaped heads, with lean and streamlined bodies taller than humans, and slick green skin that 'shines with oily iridescence'.

Bene Gesserit Overseers
On the ocean world of Buzzell, the Honored Matres used the Phibians as overseers for the Bene Gesserit slaves, as well as to retrieve soostones from the sea, by prying open Cholister mussels. As the Phibians are capable of breathing underwater as well as on land, they can dive deeper and farther from shore than any human can.
