Fun Facts
The Southeastern Pygmy Rattlesnake is extremely small and hard to spot. They are the
smallest venomous snake in the United States. These snakes are so small in fact that they can
only be heard from a few feet away.
Currently there are approximately 3,000 snakes in the United States, only about 375 species
are venomous. This makes the Sistrurus miliarius one of the few venomous snakes in the nation.
In fact, the Southeastern Pygmy Rattlesnake is one of the most abundant venomous snakes in
Florida. Even though they are small and relatively harmless they are still in danger like many
species because of deforestation, urbanization, pollution, and being killed out of fear.
Although these are small snakes they are still considered "rattlesnakes" which means that will
inevitably be hunted. Some of the more popular
hunts are "annual rattlesnake roundups" where
people go out and hunt any type of rattlesnakes no
matter the size. Once these events are done the
proceeds usually end up going to some type
charity. Even though these snakes are feared by
many people, they are essential to keeping down
the rodent population.
The Sistrurus miliarius is classified as a "Pit Viper" because of the facial pits found below and
between the eye and nostril on both sides of the head. The pit is very sensitive to body heat and
serve as a guide to locating warm-blooded prey or predators.
The Southeastern Pygmy Rattlesnake is unique because they release their prey after striking.
Their venom takes about 15 to 20 minutes to
immobilize small animals like Frogs and lizards.
On the other hand when the Sistrurus miliarius
strikes smaller mammals like rabbits or mice it
takes about 30 to 45 seconds to immobilize
them.
The Sistrurus miliarius tend to live about 15-20 years of age and grow to be about 12 to 24
inches in length. Although these snakes have a rattle on the end of the tail, it is rarely kept
because it tends to fall off every couple of years.
