Tyrannomobyus Rex, The. A plagiostome belonging to the selachain order of fishes and relates to the killer whale, the giant moray eel, the shark, the carnivorous saurain, and the cyclops. It derives its size from the whale, the conformation of its lower jaw from the moray eel, its urge to devour anything its maw can encompass from the shark, its instinctive habit of chasing anything that moves from the saurian, and its single eye from the cyclops. Over 140 feet long, the Tyrannomobyus Rex may readily be numbered among the largest predators in the world. Its skin is studded with knobs of cartilage and black as pitch, which is why it is also called the Black Whale. The head consists of a single large slab of bone that enables it to ram quite sizeable merchantmen and send them to the bottom. Fortunately, the Tyrannomobyus Rex is almost extinct. According to many experts, the specimen that has been rendering Zamonia waters unsafe for decades is the only one still in existence. Numerous whalers have tried to kill it, but none has succeeded and many have never been seen again.
