"For years, in various volcanic regions, miners spoke about a monster known as Crystalbeard. This monster was said to have extremely rare, valuable jewels, and other treasures, on it, making it a walking gold mine waiting to be found. All who searched for this monster usually ended up being smashed by its treasure-covered chin, for letting greed get the best of them."
Uragaan is something of oddity in the food chain - it has almost no natural predators, but is not particularly predatory itself and has no competitors, preferring to consume vast amounts of plants and rock. The rocks that it feeds on are surprisingly nutrient rich, and its rock-hard lower jaw is perfectly designed to break them up, although it does make them awkward to swallow.
Agnaktor, the top predator that resides elusively in the Volcano, is not adapted to prey on full grown Uragaan; they are more suited for smaller, less well defended prey, such as Rhenoplos or Aptonoth (in the lower reaches of the Volcano). The wandering Deviljho is also poorly designed to prey on anything the same size or larger than itself; the same can be said about Rathalos, which have also been known to live in the Volcano. The Brute Tigrex along with Stygian Zinogre and Brachydios will also give Uragaan a wide berth as they too have little hope of preying on the large behemoths. The only predators capable of actively preying upon Uragaan are the rare Akantor and Alatreon.
Crystalbeard Uragaan have many of the same adaptions as Uragaan, however, there is a few differences between them. Unlike normal Uragaan, Crystalbeard Uragaan are a darker color due to special ore being a staple food in its environment. Uragaan usually rest in or on top of brown liquid oil. As a result, their tails and stomachs are usually covered in it. Crystalbeard Uragaan lives in rare areas where this liquid oil has dissolved special minerals inside of it. By resting in this fluid, minerals have crystallized on its chin and tail. Some of these ores and minerals covers the Uragaan's tail and even chin. When Crystalbeard Uragaan rolls at foes, it'll actually send these rocks flying at foes out of its range. Unlike Steel Uragaan's rocks, some of Crystalbeard Uragaan's beautiful ores have a sleepy effect to them, knocking potential predators out. Compared to normal Uragaan, Crystalbeard Uragaan are more destructive with their chin slams.
Crystalbeard Uragaan are truly dangerous monsters. The Hunter's Guild only allow hunters with special permits to hunt them down.
