| This is the rattlsnake most common in the municipality (and I say common because that is those that but sees, because are not many). It is a snake with a length of 90 cm and clear gray color until dark gray. It has circular spots in the back and a thin rattle. It is dangerous by to be common so that the antivenim does not exist in this region |
