The MH Festa livestream revealed more details about Xeno'jiiva and Safi'jiiva a few days ago.


 * It takes Xeno'jiiva a long time to emerge from its cocoon, a couple of decades or maybe even longer. Xeno'jiiva will stay in one area upon emerging to absorb the energy from the surrounding environment, continuously molting as it further grows, until it reaches adulthood.
 * When Xeno'jiiva emerges out of its cocoon, its heat organ, the glowing organ in its chest, is underdeveloped. Despite Xeno'jiiva absorbing immense amounts of energy from the veins of the earth for many years while in its cocoon, it can't produce energy on its own yet. Once it is fully grown, it can produce it on its own without the need of taking in energy from its environment. Although Safi'jiiva can produce energy on its own efficiently, it needs a considerable amount to heal wounds it has sustained. To recover from injuries, it uses the land's energy instead of its own. By rapidly increasing its metabolism, Safi'jiiva can heal its wounds quickly.
 * Safi'jiiva can use its energy infinitely compared to Xeno'jiiva.
 * Xeno'jiiva spends most of its time underground since that's where the land's energy is most concentrated at, but it doesn't have the best eyesight while young. Those extra "eyes" on its head are actually sensory organs used for detecting bioenergy in its environment.
 * Since its body is relatively soft while it is young, Xeno'jiiva uses its oddly shaped claws to absorb energy from the ground as it grows.
 * The Xeno'jiiva encountered in MHW's story was slain by our hunter. However, there was another Xeno'jiiva living in the Guiding Lands that was continuously molting as it further grew more powerful. Eventually, this other individual reached adulthood and became Safi'jiiva.
 * As Xeno'jiiva continuously molts to reach adulthood, it'll lose certain parts like its strange claws, and those extra "eyes," since it doesn't need them anymore upon becoming Safi'jiiva.
 * Remnants of those parts can be found on Safi'jiiva upon breaking its parts.
