The timber rattlesnake is a venomous snake from North America. This snake has a rattle made of horny rings at the end of its tail, which makes a sound when shaken to warn of danger.
The timber rattlesnake differs from other rattlesnakes in its calm behavior and chevron pattern on its body. It is important for nature because it regulates the population of rodents in forests and serves as prey for large animals.
Immature form that undergoes metamorphosis before adulthood.
