How can a dead rattlesnake strike accurately a reaching hand?
Rattlesnakes possess highly poisonous venom.The threat of envenomation, advertised by the loud shaking of the titular noisemaker at the end of their tails, deters many predators.Rattlesnake bites are the leading cause of snakebite injuries in North America.Large numbers of rattlesnakes are killed by humans in residential areas.Although rattlesnake may have been dead for as long as 30 minutes,it can still strike a person.Rattlesnakes have two organs that can sense thermal radiation.Heat-sensing pits on their faces serve as sensors of thermal radiation.When a mouse comes near to a rattlesnake ,the sensors of the snake are triggered by thermal radiation causing a reflex action in which the snake strikes the mouse.In the same way,the thermal radiation from a reaching hand can cause the same reflex action even if the snake has been dead for a while because the snake's nervous system continues to function. Older snakes possess more potent venom, and larger snakes are frequently capable of storing larger volumes of it.
