Tealkjaffa Jaffaian

The Jaffa (usually pronounced jah'FAH) are modified humans genetically engineered by the Goa'uld in antiquity to serve as soldiers and as incubators for their young. Their story is primarily told through Teal'c. The main difference between a Jaffa and a normal human is an abdominal pouch accessible from the outside by a X-shaped slit.[2] The pouch serves as an incubator for a larval Goa'uld. Implanted during a "coming of age" rite known as a prim'tah, the pouch improves the Goa'uld's ability to successfully take a host upon maturation from 50% to nearly 100%. The Goa'uld have a device capable of quickly transforming humans into Jaffa.[50] The larval symbiote grants the Jaffa enhanced strength, health, healing, and longevity (more than 150 years). However, the presence of the symbiote also replaces the Jaffa's immune system, and if removed the Jaffa will die a slow and painful death that can only be avoided by either acquiring a new symbiote or by lifelong regular injections of the drug
