What primary physical feature of a viper head accommodates its large venom glands?
Answer
The broad, triangular or spade-shaped head structure
Vipers are distinguished by a broad, triangular, or spade-shaped head that appears distinct from the neck region. This specific cranial architecture is functionally essential because it provides the necessary space to house large venom glands situated directly behind the eyes. This head shape is a consistent identifying characteristic for most members of the Viperidae family, even among species that rely on camouflage.
