How are humans typically exposed to Conotoxin?

• A. Stung by a cone snail (predatory marine mollusk)
• B. Ingested from spoiled seafood
• C. Inhaling contaminated air
• D. Skin contact

Answer: (A)

Conotoxins are venom produced by cone snails and are delivered to prey (or would‑be threats) by a specialized harpoon-like tooth that injects the toxin. Humans are typically exposed through a sting from a live cone snail, usually when a person handles or disturbs the snail. The venom is injected, not ingested, inhaled, or absorbed through skin contact, so those other routes are not the usual exposure pathways for conotoxin. This is why handling a live cone snail is the recognized exposure route, and why rescue and medical care are focused on the envenomation event rather than food or airborne exposure. If stung, seek prompt medical attention for supportive care.
