Snake (Franchise)

Snakes are legless reptiles that are only mentioned in How to Train Your Dragon (Franchise).

Description
Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws.

Most species are nonvenomous and those that have venom use it primarily to kill and subdue prey rather than for self-defense. Some possess venom potent enough to cause painful injury or death to humans. Nonvenomous snakes either swallow prey alive or kill by constriction.

Function
There is no current function for the snake in How to Train Your Dragon universe.

In reality, snake venom is used in many ways in medicine. The Ball Python and Corn Snake can be even kept as pets in some countries.
