Fangs are long, pointed teeth found in various animals, including snakes, vampires, and some mammals. They serve different purposes, such as capturing prey, defense, or displaying dominance. In snakes, fangs can be venomous, injecting toxins into their prey, while in carnivorous mammals like lions or wolves, they help tear flesh. In popular culture, fangs are often associated with vampires, who are depicted as having elongated canines used to draw blood from their victims. This imagery has been popularized in literature and films, contributing to the mystique surrounding these mythical creatures.
