This is a photo of a wild Pacific Coast Rattlesnake I found while hiking Mt Diablo over the weekend. Rattlesnakes, copperheads and cottonmouths are all pit vipers. Pit Vipers are snakes with two pits under their nostrils which detect heat and enable the rattlesnake to hunt warm-blooded prey. The pits are so sensitive that the snake can determine the size of the warm-blooded animal and can even detect prey in complete darkness. Rattlesnakes have a forked tongue that they flick up and down. The tongue picks microscopic airborne particles and gases from the air and uses the sent to identify food, enemy (humans), mate, or other object or substance. We saw a lot of wildlife on this trip to Mount Diablo: two snakes, two tarantulas, two quail, two turkeys. Seemed that everything came in pairs that day!
