How does the *Naja sumatrana* propel venom during its defensive spray?

Answer

Specialized muscles contract the venom gland, forcing contents out through holes in the fangs.

The act commonly referred to as 'spitting' is a highly specialized biological process involving precise musculature control. The venom gland of the Equatorial Spitting Cobra is surrounded by specialized muscles. When the snake needs to defend itself, these muscles contract forcefully around the gland. This action generates significant internal pressure, which drives the venom out. Critically, the venom is channeled through specific holes located in the fangs, allowing for a directed, forceful projection rather than just a passive drip or spray.
