Raz K：Tarantula （Poison vs. Venom）

查了下poison和venom的區(qū)別，主要在毒素傳播途徑上的區(qū)別：

The terms poison and venom are often used interchangeably, but they actually have very different meanings. It is the delivery method that distinguishes one from the other. 

Poison is absorbed or ingested; a poisonous animal can only deliver toxic chemicals if another animal touches or eats it. Poison has to be inhaled, ingested, or absorbed. 通過呼吸、進(jìn)食或接觸感染。

Venom, on the other hand, is always injected. Every venomous animal has a mechanism (e.g., stingers, fangs, etc.) to inject toxics directly into another animal. 通過傷口感染。

So a snake bite is venomous; a poison dart frog is poisonous. Venom is stored in specific organs, unlike poison, which is located through an animal's body tissue. It is for these reasons that frog can be poisonous to touch or eat, while snakes are venomous when they use their fangs to bite. 

poison：我咬你（也包括接觸、呼吸），我中毒；

venom：你咬我，我中毒。
