Dusky pygmy rattlesnakes are found throughout the southeastern quarter of the United States (states include: North and South Carolina, Georgia, Florida, Alabama, Texas, Oklahoma, and Missouri).
Unlike other rattlesnakes who use their tail as a warning, pygmy rattlesnakes uses their rattle to lure prey. The sound is similar to a bug buzzing around.
They are classified as pit vipers due to having facial pits below and between the eyes and nostrils. These pits are highly sensitive to infrared radiation (heat) and serves as a direction finder in locating warm-blooded prey/predators.
A bite from a dusky pygmy rattlesnake is typically not life threatening and can be painful.
