Venom vs. Poison: Nature's Toxic Delivery Systems
When people spot a slithering snake or a brightly colored frog in the wild, a common question often arises: "Is it poisonous?" While the intent behind the question is clear, a biologist might gently correct the terminology. In the natural world, both poison and venom are biological toxins—substances produced by living organisms that cause harm or death in relatively small doses. However, the distinction between venomous and poisonous creatures does not lie in how deadly their toxins are, but rather in how those toxins are delivered to a target. Understanding this difference reveals fascinating evolutionary strategies that animals and plants use to survive, hunt, and defend themselves.
