Sea Monsters are giant aquatic serpent like sea creatures that live on Titan, were they have existed since after the start of the Golden Age. They can occasionally be seen with their dorsal fins and upper back just barely peeking over the waves of Titan's methane oceans. While at the CPU Core in the New Pacific Arcology in the mission Utopia you can also see the creature in full size by the giant windows although it's rather shadowy. The creatures, at lest one anyway, is also mentioned by the ghost as a large object moving under the Rig and ships although he can't pinpoint what the object is sense it's just from sensor readings of a scanable object.
