Basically they look like a small rattlesnake. They are usually around 2 feet long in adulthood. (The record wild caught one was 63.8 cm (about two and a half feet.)
I'm aware of two subspecies. The Eastern and Western. The Eastern Pygmy rattlesnake is called Sistrus miliarius barberi
The main clue to identification is their small size and distribution. Are you where they're found?
This is their range....the Atlantic and Gulf coastal plains...from South Carolina to Eastern Louisiana. If you're not here, it's probably a young Eastern rattlesnake. I never caught or saw one in Louisiana, Most of the ones I saw were in the panhandle of Florida.

The western one is called Sistrus miliarius streckeri. I couldn't tell them apart in the field other than by location. This one is more inland and is found in Louisiana and Texas ranging up to the central Mississippi River valley.

All rattlesnakes are venomous, and therefore potentially dangerous if approached or handled. Rattlesnakes are not generally aggressive and will most likely flee if given a chance to retreat. Because it is such a small snake, prey includes various insects and arthropods, as well as small mice and lizards.
Sistrurus miliarius
is nocturnal, feeding and moving almost entirely at night, spending the days under logs, rocks, or within piles of leaves. In certain parts of their range, such as areas in Florida,
S. miliarius
can be the most common snake species found.
