Leviathan (Japanese 海竜種) is a class of monsters that are specialized in swimming or burrowing. Leviathans are quadrupedal wyverns and include many top predators in the ecosystem of their environments. A fanon-made subclass by Setheo called Marine Wyvern describes Leviathans with all limbs evolved to fins and completely living in water.
