^ I don't think the Phantom Leviathan fits in with the Lost River despite the concept art. The Lost River, as it is now in the game, is too small to house a number of Leviathans like the Dunes, Crash Zone, and Mountain biomes. Based on the creature's head and mouth, it is likely a subspecies of the Reaper Leviathan that evolved to become a deep-dwelling scavenger that eats small fish like a filter-feeder. It makes more sense if it lived in the Blood Kelp Zone since there would be more to eat.

As for the Cove Tree Egg, we have to assume that the Phantom Leviathan is an apex predator of its environment like all of the other leviathans. Why would the Ghostrays circle around something that has the potential to eat them? Even if it can't eat them, it's common sense for a herbivore to run from a predator. My guess is that it's something much more benevolent, something the Ghostrays need to survive, possibly like a Lost River version of the Reefback.
