The warmer a rattlesnake, the faster it vibrates its tail. [6] Rattlesnakes tail-vibrate faster than other snakes, with some individuals nearing or exceeding 90 rattles per second. [7] [8] This makes rattlesnake tail vibration one of the fastest sustained vertebrate movements—faster than the wingbeat of a hummingbird. The movement is possible ...
Like other rattlesnakes, its tail has a rattle, which is composed of keratin. Each time the snake sheds its skin, a new segment is added to the rattle. However, the rattle is fragile and may break off, and the frequency of shedding can vary. So, the snake's age cannot be determined by the number of segments or length of the rattle.

The tail has two to eight (usually four to six) black bands separated by white or gray interspaces; this led to the nickname of "coontail", though other species (e.g., Mojave rattlesnake) have similarly banded tails. Its postocular stripe is gray or umber and extends diagonally from the lower edge of the eye across the side of the head.
Rattlesnakes receive their name from the rattle located at the end of their tails, which makes a loud rattling noise when vibrated that deters predators. [2] Rattlesnakes are the leading contributor to snakebite injuries in North America, but rarely bite unless provoked or threatened; if treated promptly, the bites are seldom fatal.
