Sauceback Cherfoi

The sauceback cherfoi split from its ancestor. Some of the cherfois were able to survive inside the digestive tract of the regal scorpion sauceback when consumed alive, which gave rise to this species that has adapted to the life as a parasite and soon spread to the other sauceback species found around the Ittiz Polar River.

The sauceback cherfois are smaller than their ancestors and lack color, becoming semitransparent. They are completely blind and changed their eye lenses into hooks to attach themselves to the intestine walls of their hosts, where they absorb nutrients from the ingested food. They are mostly harmless, although a massive infestation can lead to nutrient shortage and further infection through the hook wounds.

To find a new host, young sauceback cherfois leave the digestive system when the sauceback is moving in water, where they search with their sense of smell and taste for a small animal and dig into its body, in the hope it will be consumed by an uninfected sauceback.
