A recent meme provides a compelling clarification of the terms “poisonous” and “venomous” that is quite effective. By its logic, when an organism bites you and you succumb, it’s venomous. If you ingest the organism and suffer the consequences, it’s poisonous. If this explanation makes sense, you’ve grasped the concept. Still, there are curious scenarios to ponder: What happens if you’re bitten and the creature dies? Then you’re the poisonous one. What if the creature bites itself and you perish? That’s just supernatural. What if its bite kills somebody else? That’s sheer coincidence. If both parties bite one another and find it pleasurable? Best to keep that private.
People commonly mix up venom and poison because both are harmful substances produced by living things. Venom is an actively deployed toxin; it needs to be deliberately introduced into a victim through actions such as biting or stinging. Poison, on the other hand, is a passive toxin. The affected individual must either touch or consume the poisonous organism.
These concepts may be clear when explained but trickier to recall. When struggling to differentiate between venomous and poisonous, remind yourself of poison ivy. This plant cannot attack or inject toxins, but it can cause harm upon contact. This should help cement the idea that poison is passively transmitted. Additionally, the similar starting sounds of “poison” and “passive” can serve as a mnemonic device.
In Australia, which boasts numerous deadly creatures, one can find the perfect example: the Inland Taipan snake. Its venom is potent enough to claim the lives of 100 grown humans with just one drop, but it is not poisonous; theoretically, one could safely consume it, avoiding the venom-producing glands. Nonetheless, this is not advisable. There are creatures that are dual threats, possessing both venom and poison, so don’t hastily assume safety in consumption.
Some animals acquire their poisonous traits by consuming other toxic organisms. Poison Dart Frogs, for instance, become poisonous by eating small insects. These vividly colored amphibians carry enough poison to be lethal to ten people—certainly not a snack choice. Some snakes, such as the Keelback, are both venomous and poisonous. They are toxic because their prey consists of poisonous toads.
The natural world is wondrous and demands our respect. Encountering these remarkable animals warrants caution and knowledge.
