Grizzly bears, dogs, and even cockroaches fart. Do sea anemones? Nope. As for spiders, no one knows.

Daniella Rabaiotti and Nick Caruso’s new book, Does It Fart?, is illustrated by Ethan Kocak and debuts tomorrow in the United States. The book lists a number of animals, answers the titular question, and offers some insight into animal digestion. Like many silly ideas, it all started with a tweet—but it’s all real science, we promise!

“There’s a lot we don’t know about animal farts, and that means a lot we don’t know about animal digestion,” Rabaiotti, a Ph.D student at University College London and the Zoological Society of London, said. “It’s hopefully a lighthearted way to learn a lot of cool stuff you might not have known about animals.”
