Rattlesnakes are well-known poisonous snakes. They are highly toxic and cause the most damage in America. Although they are not fast, they are good hunters. They also use their tails to make sounds to attract small animals to kill! Rattlesnakes also have buccal nests of Agkistrodon halys. This is a thermal detection system that can detect subtle changes in the surrounding temperature. Animals will be found after passing, and then attack. They don’t rely on their eyes to capture their prey.
At the tip of the rattlesnake’s tail, there is a horny chain ring, which surrounds a cavity, and the horny membrane separates the cavity into two annular cavities, like two air oscillators. When the rattlesnake wags its tail constantly, a stream of air forms in the bubble, which oscillates back and forth in and out, and the bubble makes a “claclacla” sound.
