Snake Wyverns

Canon Info:https://monsterhunter.fandom.com/wiki/Snake_Wyvern

Snake Wyverns are snake-like, four-limbed, carnivorous reptiles of the clade Ophidraconia. Many species of snake wyverns have snake-like skulls and either a serpentine torso or a theropod/bird-esque one. 300 species are known but 3 species are the most often depicted.

Most species of snake wyvern are nonvenomous and those that have venom use it primarily to kill and subdue prey rather than for self-defense. Some possess venom that is potent enough to cause painful injury or death to humans.
