Answer

Possessing long, hinged fangs used to inject complex venom

The classification within the Family Viperidae is critically linked to the snake's morphology, specifically regarding venom delivery. Members of Viperidae are renowned globally for possessing long, hinged fangs, which are adapted mechanisms specifically used to inject their complex venom deep into a victim. This feature is a fundamental distinguishing characteristic at the family level, contrasting sharply with other venomous snake families, such as the Elapidae, which are characterized by having fixed fangs that do not hinge.
