Which term describes the specialized dentition of vipers involving hinged fangs?
Answer
Solenoglyphous
Vipers possess solenoglyphous dentition, a system where long, hollow fangs are attached to a hinge mechanism in the upper jaw. When the mouth is closed, these fangs fold backward against the roof of the mouth, protecting them from physical damage. During a strike, the maxilla rotates forward to erect the fangs, allowing for a deep and efficient venom injection that is significantly more effective at reaching target tissues compared to the fixed fangs found in other venomous snake families.
