Fangs are long, pointed teeth found in some animals, primarily used for grasping and holding prey. They are most commonly associated with snakes, vampires, and certain mammals like cats and dogs. Fangs can vary in size and shape depending on the species and their specific feeding habits. In snakes, fangs are often hollow and can inject venom into their prey, aiding in digestion and immobilization. In carnivorous mammals, fangs help in tearing flesh. While fangs are typically associated with predatory animals, some herbivores, like hippos, also have large teeth that can resemble fangs, used for defense rather than hunting.
