Physiology

Ryatroxos (Ree-Uh-Trocks-Os) is a large and powerful, quadrupedal Fanged Wyvern characterized by its crests, serpent like lower jaws and well developed forelegs. Its thick hide is littered with hard boney osteoderms and scutes as well as long acid filled spines along its back and tail which provide Ryatroxos with protection. Ryatroxos has a narrow and notched upper jaw filled with rows of razor sharp teeth and fangs and its lower jaw is able to split in a similar manner to serpents and move independently from one another. It has four powerful legs with large claws like most other Fanged Wyverns, but it is able to use its forelegs as arms unlike other fanged wyverns. It also holds its legs directly under its body as opposed to the sides. All of its four limbs have three walking digits with thick and powerful talons and pseudo thumbs to help grip objects and aid in bearing weight.

​Abilities

​As a quadrupedal Fanged Wyvern, its arms have evolved into forelegs, which allow it to move at great speeds with excellent mobility. Though its forelegs are developed to bear its weight it still has strong enough digits and claws to use as weapons. Ryatroxos have highly evolved lower jaws that have gained the ability to move independent from one another, these jaws posses large fangs that produce a highly corrosive and toxic, acidic venom that it uses to disable prey and would be attackers.  

Behavior

When not engaged in battle Ryatroxos can be seen wandering its territory in search of intruders, if it catches a scent or sight of an intruder, be it hunter or rival monster, it will proceed to attack its foe. Ryatroxos are relentless and aggressive predators. Ryatroxos usually splits its jaws when it roars at its foes, this is a threat display and an attempt to deter a would be aggressor. Ryatroxos are super-predators and are able to take the territory of other monsters with ease but unlike other powerful Monsters like Deviljho, Ryatroxos is not nomadic and tends to stick in an territory as long as it can.

​Habitat

Because of its highly territorial nature, Ryatroxos are difficult to observe but most specimens have been spotted in warm and tropical areas such as swamps, jungles and deserts and some have even been know to inhabit volcanic areas but is it assumed they can live in most other other areas as well.

In-Game Description​

Ryatroxos
N/A Ryatroxos are a unusual and large theropod like Fanged Wyvern known for their thick scaly hide, splitting jaws and corrosive venom. Among some of the largest Fanged Wyverns found thus far and with a temperament and ferocity to rival a Deviljho, this monster is a danger to even the most elite or hunters!

Ecology

Taxonomy:

  • ​Order: Saurischia
  • Suborder: Four Legged
  • Infraorder: Theropod Fang Wyvern
  • Superfamily: Splitting Jaw Wyverns
  • Family: Atrox

Ryatroxos is a uniquely evolved member of the Fanged Wyvern classification of monsters. Other members this group are the Zinogre and Odogaron.

Habitat Range:

​Ryatroxos can be found living in almost every environment even in hard to live areas like the dunes and volcano, the only environment they seem to be absent in is the tundras and other cold areas.

Ecological Niche:

Ryatroxos is an incredibly powerful apex predator that is high on the food chain. Ryatroxos can easily prey on monsters such as Aptonoth, Larinoth, Bulldrome, Velocidrome and even other large monsters such as Yian Kut Ku and Congalala. Ryatroxos are also some of the few natural predators of the gargantuan Validoth. Despite being an apex predator, Ryatroxox has to compete with other large predatory monsters. Monsters like Zinogre, Tigrex, Rathalos and Rathian are potential threats to young or sick Ryatroxos. And despite having many predators to deal with are quite deadly themselves with their corrosive venom and brute strength making them more than a match for such competition.

Biological Adaptations:

Ryatroxos most unique feature is its jaws which are able to unhinge and spread apart to aid in swallowing smaller prey whole and tearing larger chunks out of large prey similar to the jaws of a snake. Another feature Ryatroxos shares with snakes are heat sensing pits at the end of its snout that it uses to help track prey. Another unique feature Ryatroxos posses are its well developed for limbs that even have a pseudo-thumb and large thick claws used for grappling and wrestling other monsters to the ground, these forelimbs even allow it to take a semi-quadrupedal stance and aid in making sharp turns. Ryatroxos also posses a unique venom that is highly toxic and corrosive, this venom is used to weaken and soften up its prey when it bites allowing for chunks to be easier to rip off and swallow. Ryatroxos can also use its acidic venom for self defense and can spit it as a projectile that explodes on contact or be left to detonate, stream or even a mist. Despite its large size it is quite agile and can move at high speeds and even jump and pounce onto prey.

Behavior:

Ryatroxos are relentless, aggressive predators with surprising skills in battle. These skills have made hunters consider them to be one of the most intelligent and powerful Fanged Wyverns. Their territories are marked with singe marks from their corrosive venom. These monsters are mainly active during the day thus making them diurnal. While adults Ryatroxos live a mostly solitary life, the young hatch lings are known to wonder away from the mothers nest in gangs to hunt on their own from time to time.
