Snake

Snakes are typically level 1 critters, but can also be  beasts found in many areas of Azeroth. They are small, legless, slithering reptiles.

Snakes are usually not aggressive, fleeing when confronted.

They are also available as Small pets. Xan'tish, the snake vendor, wanders between the side-entrance of Orgrimmar and the Valley of Spirits.

Snakes should not be confused with serpents. Serpents are (since patch 2.0.1) a family of tameable beasts. Serpents tend to be larger, and hold their heads upright.

Species
Constrictor snakes hunt for food, but do not attempt to make a meal out of any creature that seems too large to constrict. Constrictor snakes hunt by grabbing prey with their mouths and then squeezing it with their powerful bodies. Some druids choose them as their an animal companion.
