What action is generally required by an opisthoglyphous snake like the Parrot Snake to effectively deliver venom during a defensive bite?

Answer

Chewing

This anatomical setup generally requires the snake to chew rather than execute a quick, forward-striking injection, making envenomation less likely during a defensive bite.
