The rattlesnake is a tube-toothed venomous snake that varies in size from species to species, but with small scales on the top of its head. Rattlesnakes are generally about 1.5 to 2 meters long. The body is yellow-green, with a diamond-shaped dark brown spot on the back. The end of the tail has a series of horny rings, which are the remnants of multiple molts.

Rattlesnakes eat rodents and other small animals (such as rabbits), they will Quickly suppress prey with toxins, rather than squeezing. These toxins can paralyze or kill the prey immediately. When encountering an enemy or moving rapidly, swing the tail ring of the tail quickly, it can swing 40~60 times per second, and it can make a loud noise for a long time, causing the enemy to dare not approach or be scared away, so it is called a rattlesnake .
