  • Experts warn that the highly venomous cone snail poses a significant danger to swimmers and divers.
  • The snail's sharp, harpoon-like tooth can inject a potent neurotoxin, potentially causing death within minutes.
  • Divers are advised not to touch cone snails and to handle them only from the rear if absolutely necessary, ensuring the venomous tooth is retracted.

The ocean harbors many creatures beyond human comprehension, with some posing deadly threats. Among the most dangerous is the cone snail, a marine mollusk whose venom can be lethal. Marine volunteer captain Chen Jinchuan emphasizes the extreme danger, urging people to avoid touching these creatures.

The cone snail possesses a sharp, harpoon-like tooth that can be fired with venom. Accidental contact can lead to severe injury or even death, particularly from the highly toxic "geographus" cone snail, also known as the "killer cone snail." This species' venom can be fatal within minutes.

If you want to catch a cone snail, you must not grab it from the pointed end. That is the position of its mouthpart (venomous tooth). You should grab it from behind and make sure its mouthpart has already retracted.

— Chen JinchuanExplaining the safe way to handle a cone snail to avoid envenomation.

Chen advises that if one must handle a cone snail, it should never be approached from the front where the tooth is located. Instead, it should be grasped from the rear, and only after confirming the tooth has been retracted. He notes that many first-time divers, driven by curiosity, reach out to touch them, leading to injuries from the suddenly deployed venomous tooth.

For first-time divers who see a cone snail, curiosity might make them want to reach out and touch it. If they grab it from the front, they will be injured by the suddenly fired venomous tooth.

— Chen JinchuanDescribing the common cause of injury when encountering cone snails.

Cone snails, found in tropical and subtropical waters, are predatory. Despite their colorful and attractive appearance, they harbor a deadly neurotoxin, making them one of the most venomous invertebrates. Their venom, composed of various conotoxins, is delivered through a specialized radular tooth that can pierce diving suits. With over 800 species and varying toxicity, there is no specific antivenom. Medical treatment relies on supportive care, such as artificial respiration.

Experts recommend observing cone snails from a distance and refraining from touching them. Even dead or retracted snails can retain venom and their dangerous structures. While their venom is potent, scientists have successfully isolated specific conotoxins to develop targeted painkillers for chronic pain treatment.

The 'geographus cone snail' (killer cone snail) is extremely toxic, and can cause death within minutes.
