Did you ever think about it?
An article from MSNBC about how insects breathe startled me on a couple points. First was this picture:

Man, is that more than a bit scary looking or what? And kind of disgusting, too. It's a spiracle, one of the many breathing holes that insects use instead of noses.
Then I realized I had never before thought about how insects breathed. Yeah, I've seen the pictures and films of those spiders that blow bubbles of air around them to breathe while they are underwater feeding, breeding, or whatever. I've been through lots of biology textbooks. And I really enjoyed A Bug's Life. But it never struck me that insects don't have noses. Come to think of it, none of the characters in that movie had noses. How'd I miss that?
