Meganox eggs often levitate in the air. Thankfully they don't fly away from their owners though (it is important that Meganox first-time egg owners touch the egg to create a psychic imprint upon the creature).
Meganoxes are considered to be the most dangerous creatures on Ark because of their combined telepathic and telekinetic powers. It has been suggested, but not proven, by the Science and Research Center in Ark City that, if enough Meganoxes were gather to share their collective mind power in a "psychic pool," they might have the ability to sink the entire island of Ark beneath the surface of the ocean or much worse. Meganoxes themselves, however, do not know their own strength.
This hasn't occurred to date (yet) because Meganoxes are incredibly compassionate and understanding in terms of their character. It is unthinkable for a Meganox to commit a crime, cause pain, or to avoid a human being or other living creature. They are lovers of nature and things that grow too.
That being said, the Science and Research Center in Ark City closely monitors Meganox activity and would take extreme measures if a legion of them gathered. For now, they are cautiously referred to as a type of guardian of the island.
