Western Diamondback Rattlesnake wakes me up!
Western diamondbacks are pit vipers. This means that they have a heat sensing pit (loreal pit) located behind each nostril that can detect differences in temperature, sometimes differences that are only a fraction of a degree apart. The heat given off by an animal is detected by the snake helping it to determine predator from prey. Western diamondbacks are poor climbers. When threatened, they usually coil and rattle to warn aggressors. They are one of the more aggressive rattlesnake species in the US in the way that they stand their ground when confronted by a foe. If rattling does not work, then the snake will strike in defense.These snakes can move their rattle back and forth 60 times per second.
