Dogs do it. Millipedes do it. Dinosaurs did it. You do it. I do it. Octopuses don't (and nor do octopi). Spiders might do it: more research is needed. Birds don't do it, but they could if they wanted to. Herrings do it to communicate with each other.

Dozens of noted experts began weighing in on which animals do and don't fart, and if they do, how much, how often, what it's made of, what it smells like, and why.
