The term "venom" stems from the early 13th century Anglo-French and Old French venim, which derives from the Vulgar Latin venimen" and the Latin "venenum," meaning poison. It earlier (pre-classical) referred to "drug or potion," and probably originated from "love potion" and is thus connected to "Venus" (erotic love). The figurative sense of "bitter, virulent feeling or language" was also recorded as far back as the 13th century.
The terms venom/poison and the associated adjectives venomous/poisonous are often used interchangeably, but incorrectly. Both venomous and poisonous animals produce a toxin that is injurious or even lethal to another organism. The real difference between the two terms involves how the toxin is delivered.
Venomous organisms deliver or inject venom into other organisms, using a specialized apparatus of some kind (usually fangs or a stinger). Venomous animals include snakes, fish and various insects. Some of the most deadly include the stone fish, the blue-ringed octopus, the inland taipan snake, the Brazilian wandering spider and the box jellyfish.
Poisonous organisms, on the other hand, do not deliver their toxins directly. The entire body, or large parts of it, may contain the poisonous substance. These organisms may be harmful when eaten or touched. Various species of frogs are poisonous for instance. Outside of the animal world, substances that are toxic are referred to as poisonous, not venomous.
