This is the fangs of a rattlesnake, an authentic biological needle designed to inject venom. Its hollow structure allows it to act as a natural syringe: when the snake bites, the muscles press the venom glands and it flows down the internal channel to the tip, entering directly into the prey. These fangs can measure up to 3 centimeters and fold back when the mouth is closed.
The most surprising thing is that the snake can replace them several times throughout its lifetime, always ensuring its most accurate defense mechanism.
