| Background | The citizens of Antos IV are noted for their unusual abilities of cellular metamorphosis, the only Federation world that exhibits such characteristics (somewhat similar to the Chameloid Homeworld and the Founder's Homeworld in the Gamma Quadrant). The characteristic is different on Antos IV in that it is not a genetic trait, i.e.- it is an acquired ability that can be taught to non-Antosians. However, by Antosian law, such techniques are no longer taught to non-Antosians, as doing so usually induces dangerous insanity in the subject, as demonstrated by the example of Captain Garth of Izar in the 2260s |
| Editors Notes | Antos IV is also noted for its species of giant energy-generating worms. |
