Poison vs. Venom: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 23, 2023
Poison is a harmful substance absorbed, ingested, or inhaled, while venom is a toxic secretion injected by animals through stings or bites.
Key Differences
Both poison and venom are substances that can cause harm or death to organisms. The major distinction between the two lies in their modes of delivery and how they interact with their target.
Poison refers to any substance that, when introduced to an organism, can cause harm. It might be ingested, inhaled, or simply come into contact with the skin. Plants, animals, and various chemicals can all be sources of poison. In contrast, venom is a specialized substance produced by certain animals, specifically to incapacitate or harm their prey or as a defense mechanism.
Venomous creatures, such as snakes, spiders, and certain fish, have evolved specialized structures like fangs, stingers, or spines to inject venom into their victims. On the other hand, poisonous creatures don’t typically deliver their poison actively. Instead, harm occurs when a predator eats or touches them.
It's essential to recognize this difference in the event of a harmful encounter. For venom, quick medical attention might involve neutralizing the venom or treating a bite or sting. For poison, treatment could entail eliminating the poison from the system or neutralizing its effects.
In cultural contexts, poison often carries connotations of intentional harm, such as in cases of poisoning. Venom, meanwhile, is usually associated with specific animals and their natural behavior, often not directed intentionally at humans.
