Dani Rabaiotti did n’t expect to become something of an expert on animal flatus . It all started on a family vacation when the animal scientist ’s comrade ask her if snake farted . She realized she had no thought . But through a close community of animal researchers on Twitter , she know someone who did .
When she asked David Steen , a wildlife ecologist and snake expert at Auburn University in Alabama , his tweeted response was a beleaguered " < sigh > , yes . " It turns out , Steen gets this question quite a spate — and he ’s not the only one . Usingthe hashtag # doesitfart , scientists who analyze everything from parrots to elephants weighed in with their own answers on which of Earth ’s immense array of animals does and does n’t claxon .

From that snowballing Twitter conversation , Rabaiotti and her co - author Nick Caruso , an ecologist at the University of Alabama , have produced a delightful and informatory book called — what else ? — " Does It Fart ? " ( Hachette Books , 2018 ) . The book chronicles flatulence behaviors of species across the animal kingdom , from insects to top - floor predator ( include a couple nonextant ones , such as dinosaur ) .

For Rabaiotti , writing the rule book ( which will bereleased in the U.S.on April 3 , 2018 ) is a prime example of " the weird places that studying zoological science can take you , " she told Live Science .
How frequently an animal breaks wind — and how biting its emission are — depends on several factor , including wellness , dieting , gut microbes and the length of the animal ’s digestive tract . Cows , goats and other members of the family Bovidae have four stomach packed with lots of methane - producing bacteria , for example , that release gas that exits the animals ' bodies mostly through the sass but also through the back ending , Rabaiotti said . Foods gamey in fiber can make for more - frequent flatus , while meat can produce H sulfide as it is digested , give flatus that paint - peeling rotten - orchis smell , according to Rabaiotti .
Perhaps the most surprising fact Rabaiotti learned while researching the book , she pronounce , was the way the larva of one mintage of beaded lacewing — a character of winged dirt ball — farts on the head of termites to incapacitate and at last kill the prey for food . It ’s the " best example of earnestly deadly fart , " she said .
She said her favourite bit of enquiry , though , was a newspaper that describe herring farting , which were discovered unwittingly . Herrings gulp air at the piss ’s open and salt away it in special swimming bladders , then release it from their anal retentive ducts , scientist think , as a shape of chemical group communication as they shoal ( or float together in a large group ) . " The best bit is that it ’s too high - pitched for predatory Pisces to learn , " Rabaiotti said . [ Does It Fart ? 10 Fascinating fact About Animal Toots ]
But the nastiest farts are the suspect stinker of seals , she said . " This is from personal experience . Seal farting are the grossest . They ’re perfectly foul . "
But the book is n’t circumscribe to giggle- and gag - induce fart facts , though there are plenty of those . Rabaiotti and Caruso use the topic as a jump - off point to explore the similarities and differences among animals , what their digestive habits can give away about them , and how scientists can use farts to locate animals .
" Farts can be kind of useful , " Rabaiotti say .
The book also touches on the exposure of certain species . The generator note , for object lesson , that the formerly frequent sound of brassy farts from rhinoceros have dwindle as populations have been extinguish by trophy search and habitat destruction .
Rabaiotti tell she has had a love for animals since she was a child see nature documentaries with her granny . She ultimately followed her dream of exploit toward a Ph.D. in zoology at the Zoological Society of London , where she is study how climate change is pretend African wild dogs ( yes , they ’re in the leger , and yes , they unquestionably fart ) .
Each of the 80 creature in the book gets a Sir Frederick Handley Page that answers the titulary question with a " yes , " " no , " " maybe " or " unknown , " along with a unretentive indorsement . The array of farting species , humorously drawn by artist Ethan Kocak , is labored on mammals , peculiarly hierarch , but that ’s partially due to the available research , Rabaiotti said .
And when it comes to sure beast , such as spider or bats , scientists do n’t in reality cognize if the tool pop off gas .
" I recall there ’s actually a surprising amount of animate being that do n’t fart or we do n’t cognize if they do , " Rabaiotti said . " I consider a lot of species have understudieddigestive systems . "
Spiders , for example , do much of their digesting before they actually scarf down their prey , injecting them with venom that help break down the meals . But the arachnoid in all probability take in air when they do dine and have the bacterium in the sacs that serve them brook , so it ’s possible they fart , Rabaiotti said . " The accuracy remains a mystery until urgently needed inquiry funding is apportion , " Rabaiotti and Caruso wrote ( with an implied wink ) .
Birds are perhaps the most prominent and surprising creature that does n’t seem to fart . This could be because birds lack the gas - producing bacterium that other animals have and because quick avian digestion signify there ’s not a stack of fourth dimension to progress up any wind , so to speak , the authors wrote .
It wo n’t surprise any reader that the last entry in the book — humans — do fart , but Rabaiotti and Caruso includedHomo sapiensbecause " there is so much to say abouthuman flatulence , " she say . " It was hard picking out which facts we imagine were the most interesting . "
An example : On average , humanity break wind about 10 to 20 time per day .
As for what comes next , Rabaiotti jest that if the book sells as well as the " Harry Potter " serial publication , the researchers could open a science laboratory to take off answering some of those capable fart questions . If it even does pretty well , she and Caruso would be game for a subsequence , she say . They already have a few answers for another press beast somatic function query : Does it disgorge ?
