The Trask egg is referred to as “The Alien Flower.”
Trasks are swamp creatures from outer space. Nobody knows how exactly they arrived on Ark, whether it was by actual alien contact or perhaps through The Mysterious Asteroid.
In general, Trasks cover themselves with vines and stay out of sight. They cannot be seen unless they want to be seen. Trasks stay in the colder waters to regulate their internal temperature better. Tropical climates cause Trasks to perish.
