Keryhs

The keryhs genus group replaced their ancestor the bistage osse and spread globally. They have a two stage life cycle, the larvae begin life when an egg implants in the intestinal wall of a fauna. They then grow into a fleshy mass with two curved prongs holding them into the wall and six tentacles exposed to the digestive slurry. Predigested food is absorbed directly across the skin of the tentacles because at this point in life the digestive system is simply a pit between the prongs.

The adults are free living and are found in wet soil and small ponds. Species found in volcanic habitats retain the ancestral ability to metabolize sulfur. In many species one or more pairs of tentacles is adapted into fins, ether ridged for stabilization of flexible for propulsion. At this stage the digestive system is fully developed and little if any ingestion takes place across the skin In most species the moth is scoop shaped but in others it retains the prongs of the larval stage. The adults are capable of reproducing both sexually by releasing both male and female gametes and asexually by budding.
