(via Great moments in pedantry: Poisonous vs. Venomous – Boing Boing)

When that snake bites you, is it poison or venom seeping through your blood stream? What about when you snack on that poison dart frog? Poisonous and venomous may seem interchangeable, but they have very distinct definitions. And if you’re the Seussian looking loris (pictured), then you are both! 

The accepted rule is: if it bit you, it’s probably venomous (delivered through injection). If you rubbed up on it, it’s poisonous. The more you know!
