Known as the "Sand-Mouth Wyvern." A large Leviathan that inhabits the sands of desert regions. It does not speak human language or roar. It is about 20 meters long, medium-sized for a Leviathan. It is characterized by a massive head that accounts for about 30% of its total length and a mouth that splits open all the way to its neck. It possesses vibrant body fluids with excellent water retention, allowing it to adapt to harsh environments by circulating them. Having evolved uniquely in the sea of sand, it hides beneath the surface to ambush prey, true to its name. It reacts sensitively to sound, using it to locate prey. It then swallows its target whole, sand and all, with its giant mouth. It has gill-like organs to filter food from the swallowed sand, from which it vigorously expels sand. Despite its sluggish appearance, it moves quickly and is constantly in motion. It employs a variety of attacks while keeping distance from the hunter, such as biting, charging, lunging from underground, and a breath attack that spits out massive amounts of sand. Because of this, opening for attacks are rare, often making it a frustrating opponent for melee weapon users. Additionally, it may perform a spinning attack when recovering its posture from a downed state. Overall, it is a difficult and time-consuming nuisance to fight. However, if one understands its characteristics well, it is possible to handle it more safely. By exploiting its habit of swallowing anything whole and making it eat Large Barrel Bombs, you can cause an explosion inside its mouth to create a significant opening. During this window, you can throw a lure into its mouth and fish the Nibelsnarf out.
