Snakes are legless reptiles that are only mentioned in DreamWorks Dragons franchise.
Snakes are reptiles belonging to the Suborder Serpentes. They have no legs and are thought to have evolved from burrowing lizards. Snakes are also known for their "unhingable" jaw, which allows them to swallow prey much larger than their heads, like small mammals, birds, reptiles, eggs, and insects. Many snake species are also able to inject venom through their fangs, which can fold down in the mouth when not in use. Venom is actually modified saliva used in hunting and in defense. The potency of venom varies greatly between species from a minor irritant to deadly to humans. Sea snakes have the most deadly venom in the world.
There is no current function for the snake in DreamWorks Dragons universe.
In reality, snakes can be eaten by humans, used for their skins, and even kept as pets, such as the Ball Python and Corn Snake. Snake venom is used in medical research, as well as formulating antivenom treatment to counteract a poisonous snake bite.

In a communication with the Entertainment News Site, Empire Online, DreamWorks Animation character designer Simon Otto, describes Barf and Belch (and by extension, the Hideous Zippleback species) as being "influenced by cobras in the way their head and tail movements are fluid and mesmerising, but they walk more like horned lizards or komodo dragons."
Simon Otto states that "Nightmares also have snake-like attributes in their behavior."
According to Simon Otto, Toothless (and perhaps the Night Fury species, was inspired by multiple animals, including snakes: "His [Toothless'] personality, appearance and behavior is a mix between a horse, wombat, kangaroo, bat, snake, dog, cat, panther and a bird of prey."
This Mystery Class dragon is based off some species of venomous snakes.
|“||Giant winged snakes with venomous scales and fangs, Slitherwings are truly the stuff of nightmares! Like regular snakes, a Slitherwing’s bright coloration indicates its venom level.||”|
